"Angepasste Einzelfalllösungen unter wegweisenden politischen Rahmenbedingungen statt detaillierter administrativer Vorgaben- ein Plädoyer für die Ingenieur- und Rechtskunst"

Beginnend mit dem Schiller-Zitat "Das Gesetz hat zum Schneckengang verdorben, was Adlerflug geworden wäre",
fordern die Autoren ein Überdenken unserer deutschen Genehmigungsverfahren in Richtung angepasster, flexibler administrativer Vorgaben, u.a. damit sich innovative Infrastrukturformen (z.B. Hamburg Water Cycle) besser verbreiten können.

Kern der Forderung: Das Kreislaufwirtschaftsgesetz für Abwasser öffnen.


Eine Antwort:

Kreislaufwirtschaftsgesetz für Abwasser öffnen - u.a. mit "flexibleren Geschäftsmodellen" wie z.B. TURNTOO !?


Sehr geehrte Herren Londong und Hartmann,

Danke für Ihren mutigen Beitrag im Tagungsband: 47. Essener Tagung für Wasser- und Abfallwirtschaft. 19.3.-21.3.2014 in Essen. Aachen 2014. ISSN 0342-6068.

Nur kurz (weiter unten ein sehr langer Text), als Anregung zur notwendigen Evolution in der "Ab"-Wasserwirtschaft, bitte in die möglichen "temporären Ausnahmezustände", z.B. in den beiden Test-gebieten Thüringen's, auch "flexiblere Geschäftsmodelle" siehe Beispiel "TURNTOO" zur Kreislauf-Ökonomie (performance based Geschäftsmodelle: turntoo.com/en/about-turntoo/) aufnehmen, via "Versuch und Irrtum".

Eventuell ist Ihnen der erste Artikel in der "wwt" vom Oktober 2013, zur eher technisch gewollten Evolution auf ZKA's, via dem robusten "Ackergaul" ABR (Anaerober Schikane-Reaktor) + Stirling-KWK, zur "einfacheren" Nutzung des Kohlenstoff im häuslichen Abwasser schon bekannt?! PDF in: www.aqua-verde.de/dokumente/ Aber auch auf den ZKA's geht's nicht ohne "flexiblere Geschäftsmodelle", um via NASS wirkliche Rohstoff-Kreisläufe zu erzielen. Rein technische Lösungen, wie z.B. Trocken-Trenn-Systeme, Vakuum-Systeme aber auch o.g. ABR+Stirling-KWK, haben in herkömmlichen AZV-Administrationen und in ÖPP's, basierend auf Abwasser-Satzungs-Geschäftsmodellen mit politisch/ökonomisch limitierten Entsorgungs-Auftrag, wenig bis keine Erfolgsaussichten. Einige inovative Ausnahmen zum blossen "Satzungs-Denken", durch einige GF's initiiert, bestätigen diese "Regel".

Betreff: "TURNTOO" as a profitable business model for "Resource SECURING Sanitation Systems" (aka EcoSan=NASS)?

Sehr geehrter Herr Londong,

Ich komme noch mal auf den gestrigen NASS-Worshop zurück.

Sorry fürs Englische und die extreme Textlänge, um einen Diskurs zum Thema im forum.susanna.org anzuregen, musste ich das Thema in einer internationaleren Sprache formulieren. "Nur" Frau Lautenschläger (wifa) hat bisher einen wirklichen Diskurs aufgenommen.

Kurzfassung:
In meiner Arbeit als Wasser-Ingenieur auf meiner Suche nach "vernünftigerer Arbeit" bin ich mehr und mehr vom Consulting-Unwesen "abgedriftet". Von einem anderen Suchenden bekam ich beim "Abdrifteten" den informellen Hinweis zur "Solaren Kreislaufökonomie", dem C2C-Konzept. Doch anfangs (2-3 Jahre) missverstand ich dies auch nur als neue Amerikanische Verkaufsmasche/Hype/Verarsche und legte es in der Kopf-Schublade unter Blödsinn ab. Ja, auch ich bin ja selbst nur ein Ignorant, stellte ich im Nachhinein fest...

Doch noch immer sehe ich C2C mit bleibender Skepsis, in Bezug auf fehlende Systeme zur praktischen Umsetzung. Dennoch sehe ich darin schon eine “Strategie der Hoffnung”, eine Hoffnung, die ich für einige Jahre schon aufgegeben hatte. Aus dieser positiven Veränderungen heraus, kann ich das Wort "innovativ" nicht mehr mit den herrschenden Ver-& Entsorgungssystemen in Verbindung bringen, im Sinne des Begriffs der Entsorgung (Verbrennen, Verscharren, Umbenennung von Sondermüll in Wertstoff usw.?) oder nur Teile davon. Zum Verständnis, bestehende gute oder weniger gute Systeme (besonders in der bestehenden Entsorgung-Wirtschaft) nur noch etwas effizienter zu machen ist noch nicht innovative, wenn es effektive doch um was anders gehen müsste und muss, die Erhaltung von Ressourcen zum gegenwärtigen und zukünftigen Nutzen.

Die Solare Kreislaufökonomie wäre da ein Ansatz, Philosophie oder Konzept oder wie auch immer man das nun nennt. BRAUNGART predigt sehr viel bei den Herstellern über diese Philosophie und betonte dabei sinngemäß: 'dies bringe indirekt auch den Erhalt von Gewinnen und sei für sie auch Überlebensnotwendig um zukünftig im Geschäft zu bleiben' , m.e. mit der Hoffnung, dass deren Überlebensinstinkte schon selbst die notwendigen Systeme zur C2C-Umsetzung erzeugen werden. Aber das geht m.e. so nicht weiter. Thomas RAU (turntoo.com/en/about-turntoo/) sieht dies und kommt von der anderen Ecke nun rein, er sieht, dass dieses C2C nur durch beidseitigen Nutzen für Kunden und Unternehmer umzusetzen geht (nicht nur zum direkten Nutzen vom Unternehmern), auch kann sich nicht jedes Unternehmen sein eigenes "turntoo" System zwischen sich und den Kunden selbst schaffen. TURNTOO ist m.e. ein innovatives C2C-"Werkzeug", ein System oder auch Geschäftsmodell, die Kreislaufökonomie zwischen Herstellern und Kunden in der tägliche Praxis zum Arbeiten zubringen, zum finanziellen Nutzen der Hersteller und Kunden. Und es hat einen als selbstverständlich begriffenen By-Effekt, den "Schutz und Erhaltung der Umwelt + deren Menschen". Dieses Geschäftsmodell erzwingt dies nicht über Gesetze und Kostensteigerungen für Unternehmer und Kunden. Es ist m.e. kein indirektes Ökodiktatur-Modell der Grünen oder Linken.


Original:
I am cracking my small "MSc-head" on the "biological cycle" of business orientated “EcoSan=NASS” systems. Maybe you have a better thinking and more ideas on this with your bigger "PhD- head"?

May you have and maybe interested colleagues too a look at this business model:

On circular economy (C2C) a realistic linking between producer and customer is missing, which means an appropriate business model, is missing to bring it to real life. E.g. an economical viable system to transfer "used" raw-material from USER back to Producer. Producers are interested in circular economy for economic benefits only, but still have problems to make it work on large scale for their own and USERs benefits. Additional, peaceful international systems aren't in place & will not be put in place, to have raw-materials secured and equally distributed.

Thomas RAU is trying to make the philosophy of circular economy (C2C) work in reality, through a "performance based system" to secure raw-materials, with an environmentally friendly moneymaking business model, called "TURNTOO".

As far as I understand, the "SERVICE-Provider TURNTOO" starts to make it work on the "technical cycle", for the beginning circular economy (C2C). Basically in order to keep technical raw-materials "alive & available" for future users (future generations of producers & USERs), this will stop the accelerating paste of permanent wasting/destroying of more and more raw-materials.

This approach is acting as a kind of "SERVICE-Provider" between Customer & Producer. The former Customer is becoming a USER and only purchases from Producer the "performance of a product", but not the raw-material by itself, instead of the whole product (e.g. 10,000 hours washing, but not the whole washing machine). Therefore the product is cheaper for the USER too. After end of performance period with USER, the "SERVICE-Provider" is collecting as a service mainly for the Producer, the used product (raw-material) and returning it to its raw-material-bank (pool) and finally back to the owner.

Through this kind of SERVICE the Producer becomes an economic benefit of secured availability on raw-material and security on future price developments outside the speculative commodity market.

As far as I understand, the profit margin + costs + risks share involved for the "Raw-material- SERVICE-Provider" is paid by the Producer only & very direct. This amount is near equal to the amount the customer pays less for the product. To start production process and cycle, the SERVICE-Provider has to pre-purchase raw-material from the speculative commodity market (e.g. from steel providers). The Producer is purchasing from the "SERVICE-Provider`s" raw-material bank (pool). The ownership and return of raw-material is later secured by the paid service-provider. As a by effect, a system like that has many more them only economical benefits. Social, ecological and health: e.g. jobs through service providing; through less raw-material exploration and less energy intensive base-material converting.

www.turntoo.com/en/how-turntoo-functions/






What do you think and what would be your advice on "biological cycles" (consumed biological raw-materials) via a business orientated Service-Provider, like TURNTOO in SANITATION?


The business model on "technical cycle" to re-use technical raw-material, like alum and steel is easier to understand.

In my opinion, "consumed" biological raw-materials in a "biological cycle" have high complexity because of many players involved. On the other side many players are needed, in order to make them finally reusable raw-material, plus having an equal sound environmentally friendly moneymaking business model like TURNTOO.


E.g. Phosphate, Humus and Energy in food and in ("used") digested human and animal food (urine and faeces in human and animal sanitation). In near future Agricultural Producers would still like to keep payable price for this precious raw-material as fertiliser & humus back on their field for new food production. The Phosphates reserves are limited, the prices will climb up without re-use-systems.

How could a "SERVICE-Provider" like "TURNTOO" do this "job" between USER and Producer in a profitable way and with economic benefit for USER and Producer for the "biological cycle" of consumed biological raw-materials? In a "performance based system" also?

The old business model for "centralised sewage collection, -treatment and -discharge", with their own lobby organisation is often profitable for a very limited number of beneficiaries. It is still spilling fertiliser, humus and energy through treatment plants via rivers to the sea. "Certification-condoms", gild, shame and horror scenarios about our all future, will not change anything or at least the mindset of the current beneficiaries of thatch systems. In developed countries, centralised sanitation infrastructure without source separation (Urine & Faeces) are in places, after many years of "trial and error".

Therefore any costly and rough "Sustainability-Revolution" will not be successful, but an evolution through "trail and error" on new business models which have more beneficiaries involved, will be successful. Any new estate development might be the best option for a wanted “Sanitation-Revolution”, for centralised new business models on decentralised and semi-centralised services (e.g. Urine Diverting Dehydration Toilets, UDDTs), providing to offer to Agricultural Producer biological raw-material by "biological cycles" (re-use).

To start an evolution (Via trail and error?) on new business models like the inventive Service-Provider "TURNTOO", the existing Centralised Sanitation System has to be used for a “Resource Securing Sanitation” (maybe aka EcoSan). In a first business step to take out Humus & Energy for sale, via low-tech, e.g. by CHP, and in a future business step, taking out the Phosphate also for sale, via high-tech equipment.

First equation (with the help of a BORDA e.V.- spreadsheet) concludes, that a minimum of 10.000 p.e. would be required, to make an investment for a possible service provider viable (this is under typical German conditions, with CHP installation cost 5.000 EUR/kWel). The surplus sludge of existing sewage treatment plant would mainly be used. This calculation is based only on sale of renewable electrical power generated. But selling additional heat for warming up buildings, might lower the number to 5.000 p.e. (by my educated guessing). Having Phosphate in future included (via high-tech) would make smaller "re-use systems" viable too.

!!! E.g. already now, farmers in DK deliver their animal manure to a large bio-gas plant and get paid depending on nutrient and caloric value of manure. Through CHP the plant sales heat and power to a nearby small town and the grid. The same farmers purchase biological fertiliser & humus with a clear stated nutrient content from the plant.

Maybe I see this all too narrowed and too complicated?

Could you follow my German-English? Are the issues involve in a "biological cycle" too complex for a profit orientated Service-Provider in Resource SECURING Sanitation?



Eventuell ist dieses Thema eine Anregung für einen konstruktiven Diskurs.

Es ist schon seltsam, als ehemaliger Kommunist "predige" ich mittlerweile in Richtung innovative profitable business model

The second link below is a tour of the exhibits (the Durasan and Rammer) that SAAB displayed together with PATH and PSI



The technologies displayed addressed different levels of the sanitation value chain, and the experience interacting with different BMGF grantees will no doubt help SAAB to continue making technological improvements that offer better sanitation solutions to households and communities.

my appologies for the late reply! The project is just starting so some of your question cannot be answert by now.
Please find below the team's reply to your questions:


Will you work with a couple of selected urban areas as pilots?

We will work in one city in India with aim of later reaching to larger context.

Since you will have a strong focus on O&M, I wonder if the infrastructural part of the sanitation system to a great extent already is in place, or will you have to invest heavily in infrastructure development as well initially?
No, we do not aim to invest in infrastructure, large number system already exist that need O&M

It would be nice to understand what will be your strategies and methods to mobilize the governments and key stakeholders?
We will update on this few month later

Will you be facilitating and supporting possible businesses opportunities for different functions along the sanitation value chain? Lastly, do you also aim at making the sanitation systems more sustainable from a resource point of view, e.g. through recycling of water and nutrients in agricultural production?
Yes, we aim to engage private sector in O&M value chain. The project will facilitate the process.

Best wishes,

If you start thinking about the post title "Structuring of the fecal sludge market for the benefit of poor households..." I would understand this project is not mainly about technology like e.g. GIS-traking of the whereabouts of "honeysuckers" or de-watering of FS (Omni-Ingestor) at the spot...

If collection and treatment is 100% driven by private service providers as it is stated, should it not start with a clear and transparent line of financial interests involved? About possible profits to be made along the FS-line, from collection of FS to sale of surplus renewable energy produced. If no profits to be made with FS-business, who will cover the losses in future?

Possible way forward:
First the state want to improve FS-situation in Dakar (just a political statement), to do so the state is starting with an incentive (maybe financial supported by WB, EU or AfDB and others):

- Incentive, a clear commitment to purchase (via realistic price) in future ALL surplus renewable energy produced by the current (converted) three and future additional fecal sludge treatment plants (in future several biogas plants + CHP) = biogas-service providers.

- This biogas-service providers having through sale of energy reasonable profits and would have to PURCHASE by then collected fecal sludge from the owners of "honeysuckers", or they establish their own "honeysucker" fleets.

- Any sewage nearly without fecal sludge, as it is currently delivered by Dakar's "honey-suckers", would have no caloric/financial value for the biogas-service providers, therefore less payments. This means, in order to keep quality of delivered FS the "honeysuckers" are paid by the fecal sludge content (TS) delivered only.

Having an energy producing system with an open & transparent financial interests involved, will minimize illegal dumping, as the owner of "honeysuckers" would loos profit and additional it would avoid e.g. costly "gadget systems" of distrust like GIS-traking of the whereabouts of "honeysuckers" and avoid too high maintenance intensive de-watering of FS (Omni-Ingestor) at the spot. For the time being, not functional lance nozzle at nearly all Dakar's "honeysuckers", would be repaired by the owners (without "capacity building"), as functional lance nozzle would increase fecal sludge content during collection and would direct increase payments by biogas-service providers.

Is it too simple and too much "believe" in commercial thinking and interests?

Best Regards,
Detlef SCHWAGER

PS: My suggestion is not at all about any PPP (Public Private Partnership), as "open honesty & transparency on financial interests" are not part of any PPP-business strategies, as democratic controls are explicitly denied by secret treaties. see: en.wikipedia.org/wiki/Public%E2%80%93pri...tnership#Controversy and bankwatch.org/public-private-partnerships]]>

I have some further questions for you which arose when I listened to your presentation (link above):

(1)
You said that the institutional set-up in Senegal is very clear, and that ONAS is well placed because it is responsible for everything to do with sanitation. On the other hand, up until now, it was not concerned with emptying of septic tanks and pit latrines, as that's done by the private sector. Isn't that a contradiction? Does that mean ONAS was only responsible for piped sanitation until now, and not for non-piped sanitation?

(2)
You said ONAS wants to phase out the manual pit emptying. Which technical solutions do you have in mind to make very thick sludge (bottom layers of pit latrines) pumpable? I can only think of dilution with water. Or converting pit latrines to pour-flush latrines maybe (to reduce the amount of solid waste), like it was proposed by Dave Still in a WRC report in South Africa.

(3)
How well are the 3 faecal sludge treatment plants that are already operational actually working? Do you have photos? When were they built and by whom? Which processes do they use? Which effluent quality do they achieve on the liquid stream? What happens with the solid part (e.g. dried faecal sludge), what is done with that? Any reuse activities?

(4)
You mentioned 2-3 innovative toilet technologies suitable for areas that are prone to flooding. What technologies do you have in mind there? UDDTs perhaps (urine-diverting dry toilets)?

(5)
I didn't understand how this call centre works that you mentioned? Does that mean residents can call up a call centre when they want their septic tank emptied and then get quoted the best possible price for their location?

(6)
Can you tell us more about the proposed biogas plant for faecal sludge treatment (you mentioned co-treatment with other organic waste). Is this entirely funded by the BMGF? Is it a full-scale plant? Why would they fund such a plant for you, what is their reasoning behind it? What is the connection here with China?

(7)
And finally a question about the Omni-ingestor: how far progressed is the development by now? Do you have any photos? Is there a prototype yet?
I read the report by the company Synapse (www.synapse.com/home-page?destination=node/427) (link to the report: susana.org/lang-en/library/library?view=...p;type=2&id=1718). The report is pretty interesting (thanks to the BMGF for commissioning the report and sharing it). This could be a big business if such an omni-ingestor could be developed. Mind you, I fear the maintenance issue could be a real headache since already the conventional vacuum tankers are not well maintained usually...

I found this schematic for a possible Omni-Ingestor in the report (susana.org/lang-en/library/library?view=...p;type=2&id=1718), is this still the design that is being pursued?

Sorry for the slow response.

On the government side we are working with the Kenya Ministry of Health. Since this relates to on-site sanitation rather than sewerage systems they are the responsible body within the public sector.

On the manufacturing side, the advisory support under the project has been made available to all firms that have expressed an interest in developing new on-site sanitation solutions in Kenya. So far, the most interest we have seen has come from plastics manufacturers. to date we have formally signed partnership agreements with three firms, Kentainers, Silafrica and Polytanks.

On the micro-finance side, we are still exploring whether this is a viable distribution channel, given that the price points for the slabs are below the minimum threshold for micro-finance institutions (without some form of bundling). So we are not formally working with any micro-finance institutions to date.

Hope that answers the questions but please do get in touch if you would like any further information!

The recording of the presentation of Mbéguéré from our webinar number 5 on "Resource recovery and reuse" on 21 January 2014 is now available.

(All the videos from our webinars with BMGF sanitation grantees held so far are now available here under this one link which leads to a Youtube Playlist:
www.youtube.com/playlist?list=PL0gMdVBup...ymOPomtqL_XYT5YtLTSK )

Mbaye had to recorded his presentation a second time because the recording from the live event was unfortunately too choppy. We thank Mbaye for agreeing to record it a second time!

Presentation title:
Structuring of the fecal sludge market for the benefit of poor households in Dakar, Senegal
By Mbaye Mbéguéré, Senegal National Sanitation Utility, ONAS, Senegal

You can watch Mbaye's presentation here (sorry about the bright window behind his face which made it hard to make out his face properly; but his voice is very clear):



Powerpoint slides from his presentation are available in the attached file below:


For the benefit of those who can't watch youtube videos very well (according to Wikipedia, these four countries have standing national bans on YouTube: China, Iran, Pakistan, and Turkmenistan), I am highlighting below some main points from Mbaye's presentation which I found important:

  1. The current cost of pit desludging is about 130 USD per year per household. This is entirely done by private service providers.
  2. The amount of faecal sludge collected in Dakar is predicted to increase rapidly from currently 1500 m3/day to 2500 m3/day in 2030 (imagine all the additional traffic this generates as well!).
  3. The plan is that the management of the current three and future additional faecal sludge treatment plants will be by the private sector.
  4. ONAS wants to improve with this BMGF-funded project the operation of each component of the sanitation chain (i.e. collection, transport, treatment, reuse).
  5. For example in terms of collection: there are areas in Dakar that are prone to flooding. Here the project wants to develop 2-3 innovative toilet technologies for flood prone areas, which should be replicable to other areas (see also here the announcement by their partner Oxfam America: forum.susana.org/forum/categories/95-cal...ood-areas-in-senegal). (would this include UDDTs?)
  6. To optimise the transport, ONAS will introduce a licencing and certification process for the operators of the tankers but also for the manual pit emptiers.
  7. There is also a call centre for emptying services; more competition amongst the private companies and hence lower prices is expected. (I didn't fully understand who this call centre works).
  8. New trucks are being developed (called "Omni-ingestor") which should achieve separation of solids and liquids inside of the truck, whereby clean water would be produced and discharged at the premises, and only the thickened sludge would be transported.
  9. The costs of faecal sludge treatment could be reduced via resource recovery initiatives. To this end, a biogas plant for faecal sludge treatment will be built with funding by the BMGF (this is part of a project between China and Senegal). (note this was also mentioned in the discussion above in this thread)
  10. Due to this BMGF support: ONAS and pit emptiers are now sitting in the same room together discussing things... this is resulting in an improved relationship between ONAS (national authority) and non-pipe sanitation service providers.

Questions during the webinar and during the re-recording:

(1)
Chris Buckley asked how the team in Dakar tackles emptying of very thick faecal sludge?

Mbaye explained that the vast majority of households in Dakar rely on septic tanks which produce faecal sludge which are very low in total solids, thus, emptying is easier (in contrast to Durban where the majority relies on dry toilets or latrines which limited water use).

Nelson asked in the re-recording also how to empty very thick faecal sludge from pits?

Mbaye's answer:
"We have pumping trucks who collaborate with manual emptiers. The trucks pump the upper liquid part, and afterwards the manual emptiers empty the lower thickened sludge part."


(2)
Chris Buckley asked if a GIS-based tracking system could be used for the sludge trucks (new system in South Africa).

Mbaye explained that the system which will be implemented by ONAS will include a tracking system. Tracking of trucks is useful and relevant; a GIS tracking system is essential. Therefore, all trucks will be geo-localised in future. ONAS will know where the trucks go and could potentially identify illegal dumping of faecal sludge.

Already now they have quite a good system of tracking sludge tankers; they know where they are, illegal dumping is no longer happening in Dakar.

The first contract has been signed for the operation of 3 existing faecal sludge treatment plants (FSTPs) in Dakar. This is important because you cannot police illegal dumping of faecal sludge if the tanker operators have no legal place where the faecal sludge can be dumped and treated properly.


(3)
Jeremy Kohlitz asked about the regulatory framework and institutional set-up.

Mbaye explained that this is very clear in Dakar where everything in terms of sanitation is managed by ONAS (in contrast to other cities where we have overlapping institutional responsibilities). This includes faecal sludge management. ONAS is a strong organisation and working well. The framework in Senegal is very clear.

(4)
Nelson asked if there are health protection measures for manual pit emptiers like in South Africa?

Answer by Mbaye:
"Manual pit emptying is still wide spread. Our objective is to make manual emptying disapper (by 2015: reduced manual emptying, introduce a licencing system). We are not so much focussing on improving the manual pit emptying for this reason."

(5)
Nelson asked about the size of the Omni-Ingestor

Mbaye's answer:
The Omni-ingestor would be processing the faecal sludge on-site with the aim to separate clean water from it, so less water would have to be transported. Currently a vacuum truck can carry about 8 m3 of faecal sludge. This faecal sludge typically has a concentration of 4 g of dry solids per Litre (this means it is quite thin). The Omni-ingestor should thicken this up to 20 gTS/L inside of the tank (i.e. on-site), which means one Omni-ingestor would have the capacity of 5 ordinary trucks (or could empty 5 times as many pits or septic tanks before it is full).



Thanks very much to the presenter (Mbaye) and to the people asking questions during this webinar! Once again, a good presentation raises more questions - I have a few more which I will put in a separate posting later. If others have questions to Mbaye, feel free to ask here.

I know that you are just recently starting up your activities, but I hope you can answer some questions I have to get to know your project better.

Will you work with a couple of selected urban areas as pilots? What does the sanitation situation look like at the outset of the project? Since you will have a strong focus on O&M, I wonder if the infrastructural part of the sanitation system to a great extent already is in place, or will you have to invest heavily in infrastructure development as well initially? It would be nice to understand what will be your strategies and methods to mobilize the governments and key stakeholders? Will you be facilitating and supporting possible businesses opportunities for different functions along the sanitation value chain? Lastly, do you also aim at making the sanitation systems more sustainable from a resource point of view, e.g. through recycling of water and nutrients in agricultural production?

Looking forward to hear more about your project!
Thanks and best regards,
Kim]]>

Re: Modelling the next generation of sanitation systems - NewSan Simulator (University College London, UK) - by: dorothee.spuhler http://forum.susana.org/forum/categories/97-enabling-environment/4741-modelling-the-next-generation-of-sanitation-systems-newsan-simulator-university-college-london-uk?limit=12&start=12#7260 http://forum.susana.org/forum/categories/97-enabling-environment/4741-modelling-the-next-generation-of-sanitation-systems-newsan-simulator-university-college-london-uk?limit=12&start=12#7260
Nelson from SEI asked some questions at the end of the re-recording of Luiza's presentation. As volume is quite low, we thought it would be worth to complete the write-up also with a summary of this discussion.
So, here you go…

How do you acquire the input values in order to run your simulations?

The model is based on a simple Material Flow Analysis which needs for the simulation input data and process in order to calculate output flows
Currently all the data used was collected from the literature: input concentrations as well as what happens in the process: e.g. energy consumption or production, decay of nitrogen etc.
Currently only examples were simulated based on the data from literature (e.g. the one's you have see on the diagrams in the presentations).
In the future, the model needs to be validated and calibrated. For this, case studies are needed from places were systems with similar outputs as NewSan produced are implemented. The problem is that most of the technologies, NewSan is looking at only exist at pilot scale and even data from pilot scale does vary if you scale up.

What are the Phosphorus and Nitrogen flows through the system on the slide with the UDDT?

The slide is only showing CAPEX and OPEX. But the simulator can also calculate phosphorus and nitrogen flow or any other of the currently available options (e.g. coliforms, carbon, BOD). They are calculated based on the settlement data which determines the inflows and the transformation and transportations they undergo through the systems.

Are you aware of the washcost project IRC has in the Netherlands has been carrying out?

Yes, and washcosts data was used in the in the work so far. A future collaboration would be welcome but currently, the NewSan Prototyp needs funds.
To have financial resources would help the team to keep the development going more and to validated and calibrate it.
See e.g. here for more info on washcost:
forum.susana.org/forum/categories/55-wg-...f-project-evaluation
forum.susana.org/forum/categories/55-wg-...proach-to-sanitation
forum.susana.org/forum/categories/139-ge...imit=12&start=12
forum.susana.org/forum/categories/55-wg-...proach-to-sanitation

----

So if you have are working on the implementation of the “new generation of sanitation systems” and have a case study or data to offer to the team, especially on anaerobic digestion or biochar production, let them know...

Cheers, Dorothee]]>

If possible may you in-cooperate results and calculations by Mr. Sharma and colleagues in your project “NewSan” simulation tool? Is your coming system flexible enough to do so?

Although it is stated, all is based on typical Indian condition, in my educated guessing this conditions are very representative to too many places on earth.
