Thermopile Anaerobic Baffled Reactor (ABR)? For ready deployable Biogas-SPEEDKITS for refugee camps
FP7 - Research Theme: Security, 2012-2016

Dear Jan,

With great interest I informed my self about your ongoing biogas project, SPEEDKITS for refugee camps.

May I draw your attention to an already existing much simpler (low-tech) bio-gas plant design, called Anaerobic Baffled Reactor (ABR), it do not need much pumps or some stirring devices. An ABR can cope with shock loads and do not need expert O&M-staff, or any external power supply and pump, if at least a small gravity of 20-30 cm is available. The "Honey-Suckers" of the refugee camp could pump their contents direct in to the 20-30 cm raised inlet-camber of the ABR. The same "Honey-Suckers" could take from the lower outlet of the ABR the sludge to drying fields...

The ABR was initially developed by Prof. McCarty and co-workers at Stanford University, USA (McCarty, 1981).

BORDAs Practical Guidebook (detailed manual) by Engineer SASSE: [http://www.borda-net.org/fileadmin/borda-net/ne..._Guidebook_small.pdf] (with detailed equations)

Maybe you go for an ready made (insulated + heated for the thermopile temperature range) very simple Anaerobic Baffled Reactor (ABR) within a used 12' or 6'Container.

Or better you make your own ABR by stacking two fibreglass body's of ready made prefab ABRs from BORDA e.V., Bremen in an used and insulated sea-container. An additional heating and insulation between the two fibreglass body's could do it to the thermopile temperature range. Maybe add on top of your self-made thermopile ABR insulated airtight fabrics for simple gas storage above the ABR it self, or store gas in a separate used sea-container (with airtight fabrics) nearby.

Prof. McCarty's original ABR-Design is "Open-Source" and do not has a user restricting Patent attached. Even if it is by other developers and companies (like Conviotec GmbH and Consentis GmbH) now called "new + innovative" and "multi-chamber fermenter" M-ABR or CON2-Fermenter + CHP 45-75kWel. (costs 5,000EUR/kWel.). Despite they attached a Patent, it is still common practise = state of the art (Stand der Technik).

I hope my hands-on view as an "biogas-outsider" is helpfull to you and your project/research outcome.

Good Luck & Best Regards,

MIT's Center for Collective Intelligence is putting out a call for innovative approaches to climate change, including adaptation.

The call is part of Climate CoLab, an online community of researchers and practitioners that is using crowdsourcing to develop climate change response strategies.

Climate CoLab is sponsoring thirteen contests that seek creative and practical solutions, innovations and business models to address climate change. Contest winners will be awarded $10,000 and have the opportunity to present at a conference at MIT.

Attached is a short flier on the adaptation contests.

I wouldn't say that quality is unimportant. The point is that at the moment we have no methods for treating large quantities of sludge in emergencies. We don't want to make the perfect the enemy of the good. Any improvement in quality is a step forward. Over time, I expect that effluent quality will increase, but we have to start somewhere and we can't reject any ideas now.

Thanks, that is a very interesting idea - I hope you get lots of entries and it generates some new thinking in emergency sanitation.

I have to record that I'm sad that in Emergency Sanitation it appears sludge treatment quality is of a minor importance in disposal. Whilst I can understand that, it seems to me to be a major flaw in the paradigm.

The Emergency Sanitation Project aims to increase the global understanding of current and future emergency sanitation. It is to propose new concepts and modular technologies for safe excreta disposal in emergency settings that are applicable in a variety of situations. A menu of options will be available through the development of specialised emergency sanitation modules, which are rapid to deploy and are cost-effective when compared with traditional solutions. ESP is looking at a wide range of issues and invites you to visit its website

Today the Emergency Sanitation Project has published two interesting contests: one on wastewater treatment and one on public urinal systems.

Re: Building Resiliency in Sanitation in the Wake of Climate Change in Developing Countries - by: JKMakowka

As much as it seems lately, climate-change is not strictly related to floods and droughts. There are some models and recent experience that suggests the likeliness of them will increase with changes in global climate, however extreme weather events are nothing new at all.

Climate change is rather related to longer term effects like salination or depletion of ground-water aquifers, shifting cultivation and pathogen patterns, shrinking of surface water bodies and such.

Thus I would suggest not to mix up issues of climate change too much with general disaster risk reduction and preparedness as it just "muddies the water".

As far as I know, there is quite extensive literature and training material on flood-proving sanitation infrastructure (the easiest is to raise above ground components and fortify the ones below) and any solution that does not use water should be pretty drought proof.

Building Resiliency in Sanitation in the Wake of Climate Change in Developing Countries - by: F H Mughal

Could somebody please provide links to the publications on building resiliency in sanitation (and water supply) systems, in the wake of climate change, in developing countries.

It would be very helpful, if SuSanA develops, down-to-earth, step-by-step guidance manual, on the top, for the developing countries. In addition, organizations like SKAT, are well-placed to conduct trainings and workshops for participants from the developing countries, on building resilency in sanitation and water supply systems.

The recent floods in Pakistan made the sanitation system completely non-functional, in the rural areas of Sindh province. Floods in Bangkok floated the drums, containing the chemicals for water treatment, at the Sam Sen Waterworks, Bangkok.

Hi,

Constructed Wetlands, like Vegetated Sand Filters, work via gravity (and solar energy collected by the plants). I can imagine setting one up quickly for an emergency, even though efficiency will improve as the plants grow.

But I would more suggest UDDTs with interchangeable containers that get changed before they get too heavy for a person to easily carry. One very accessible option is the woven polypropylene sack, which would come to the emergency bearing food. More info in my paper on Simple UDDTs in www.ecosan.at/ssp/issue-06-toilets/issue-06-toilets

Thanks for posting these.

Overall it seem like quite a lot of thought has gone into these, however I see one point where the guideline seems to be a bit lacking:

In the document about the sludge treatment part D10 & 11 deal with the power-input. As it is generally understood that efficient waste-water treatment systems are most of the time quite energy intensive, the requirements given there seem both quite steep (gasoline for 3 months of generator operation has to be included?) and yet also very non-descript as by referring only to the potential including of a generator.
Given the importance of the energy input of this component, I think this needs to be given more thought.

For example, one could easily think of the system that could be operated without *electrical* power (thus no generator requirement) to increase reliability and exchangeability of integral parts just to name an example.

As the new coordinator emergency sanitation at WASTE (see introduction below), I am proud to present the results of the emergency workshop in Delft (see link below) that has resulted in three separate documents on the 'specs', the requirements, that can be used to guide/challenge/invite the suppliers to come forward with solutions for: (1) raised latrines for emergency situations, (2) desludging equipment and (3) treatment and disposal of faecal sludge. Please have a thorough look at them and provide your feedback to This e-mail address is being protected from spambots. You need JavaScript enabled to view it .

It is obvious that these specs are not 'cast in stone' but meant as targets. If all goes according to plan, the Netherlands Ministry of Foreign Affairs might use them for a Call for proposals for Public Private Partnerships to design, prototype, field test and manufacture products to meet the challenges as part of one of the next rounds of the Sustainable Water Fund.

At the moment coordinating emergency sanitation projects at WASTE (Gouda, The Netherlands). Together with a.o. The Netherlands Red Cross Society and MSF, WASTE is participating in the S(p)eetkits project (www.speedkits.eu) where WASTE takes the lead in the WASH activities. WASTE (www.waste.nl) is an organization promoting the improvement of the living conditions in cities in developing countries. WASTE mobilizes and provides meaningful and effective support to transform waste into opportunity by mobilizing networks, ideas, knowledge and money. As a self-employed consultant a.o. for UNICEF in occupied Palestine territory, for the Dutch WASH Alliance in The Netherlands. In Indonesia for SHAW/Simavi project and for the Indonesian Infrastructure Initiative (AusAid). Previously for MWH (Indonesia, Surinam, India), Syncera, AgentschapNL (Egypt), Brabant Water (Hungary, Indonesia), IWACO (India, Indonesia) and UNCHS-HABITAT (Tanzania, Comoros).

Specific to SuSanA forum, I plan to contribute to the exchange of ideas and experiences in the field of emergency sanitation. At the moment focusing on effective ways in responding to sanitation in emergencies e.g. development of prototypes for raised latrines, superstructures, slabs, desludging and faecal sludge treatment and disposal. The SuSanA forum is also a great opportunity to investigate opportunities for the WASTE Sanitation Window (SaWi) where WASTE matches demands, interests, knowledge and funding with business solutions: from idea to market.

Dear Analiza and all,

Congratulations!
Please keep us updated on the implementation of the elaborated concepts and the evolution of Ecoville!

If you wish to read more on Ecoville, see also tabangsendong.xu.edu.ph/index.php/home)

I felt that the experiences after Sendong and in Ecoville have contributed to the change of mind-sets in the Philippines regarding sanitation, health and the opportunities of ecological sanitation and water management. Planners as well as the University are showing now a high commitment.
Indeed the training was very successful and I hope you will be able to carry out this as part of the XU and SEARSOLIN program as planned!

Here are some pictures - you may have more? We could upload them on Flickr.

Best regards Dorothee

The Xavier University Sustainable Sanitation (SuSan) Center together with the seecon international gmbh and SEARSOLIN is pleased to announce for the successful Sustainable Sanitation and Water Management: for emergency Preparedness and Response (SSWM:EP&R)workshop, held on August 13-18, 2012, in Cagayan de Oro, Philippines.

For further detail, kindly see attached file.

Sincerely,
Analiza Miso

The Xavier Sustainable Sanitation Center together with the seecon International gmbh and SEARSOLIN, conducted a 6-day workshop on Sustainable Sanitation and Water Management (SSWM) and its role in emergency preparedness and response (EP&R) cylce on August 13-18, 2012 at Southeast Asia Rural Leadership Institute (SEARSOLIN), Cagayan de Oro, Philippines.
The training course was participated by 15 groups of people coming from government, NGOs, and university. The first part of the workshop was about the concept of SSWM; followed by a second part focussing on the Emergency Preparedness and Response (EP&R) cycle and the role of SSWM throught this cylce, with a particular focus on the reconstructing phase and for resilience building after the disaster.
Field exposures were conducted in order to provide venue for the participants to have a first-hand experience on how SSWM can be applied in EP&R. The field visits were done at Xavier Ecoville temporary and prospected permanent resettlement site and at Calaanan permanent resettlement site.
Xavier Ecoville allowed the participants to get familiarized with understanding, defining and optimising the system. The outputs of a group work conducted through the whole course will be integrated in the work of SuSan Centre, in charge of all WASH components in Ecoville temporary and permanent resettlement. The permament Ecoville, currently built is designed as a model community in the Philippines and around the globe, where SSWM planning and implementation approaches are applied from the beginning. Xavier Ecoville is a being constructed on a approx 5 hectare land donated by Xavier University (XU) and intended for 550 households which participate in the process of designing and constructing the settlement. Thereby, the Xavier Ecoville Community is assisted in becoming cohesive and self-reliant; capable of initiating and sustaining projects or activities which respond to family and community needs through effective mobilisation and utilisation of resources. To facilitate this process, two teams were formed: the Physical Development and the Community Building Team. The physical development team is in-charge of any plans related to physical layout, buildings and other physical set-up of both temporary and permanent sites. The community building team is responsible for values formation and software and hardware needs of the community according to seen and foreseen needs. It is composed of seven clusters/teams: WASH, Health, Education, Shelter, Governance, Environment, and Livelihood.
The SSWM for EP&R workshop enabled the participants to understand the importance of SSWM’s role and its significant correlation with the EP&R cycle in order to reduce risks during disasters or emergency situation. The very essential output of the participants was their group works, where in each group developed or drafted their concepts notes on how to optimise SSWM for Xavier Ecoville permanent site. The drafted concept titles are: Xavier EcoVille 2015 – Community Action Plan; Developing Community Self Reliance; XU EcoVille SSWM System Establishment; SSWM System for water (rainwater harvesting; greywater treatment).
The training not only catalised new ideas on how to optimise the system in the future permanent site being currently constructed, but also foster new partnership supporting the implementation of the drafted ideas in the close future.
