David recently mentioned a costing toolkit here in this post:
forum.susana.org/forum/categories/53-fae...-concept-for-myanmar

He wrote:

We used the Septage Management Toolkit to check the numbers and they are presented in the attached Excel spreadsheet. This is a toolkit developed by USAID 9 years ago. Interestingly, we have used different versions of the toolkit in the Philippines, Bangladesh, Nepal and most recently in Indonesia for a 600 cubic meter per day project for a city of 2 million. Interesting now to try it on such a small project here at less than 2 cubic meters per day!

It is a simple tool with only 5 main tabs: i) the design flow calculator, ii) the number of collection vehicles, iii) the collections costs, iv) the treatment costs, and v) the balance sheet and tariff calculator.


Have you checked it out if it's any good?

Also there are these two FSM toolkits, do they contain what you're looking for?:

Please let us know what you find. And I agree with Reetu that it would be interesting to know more about the context of your question?

It is a great suggestion and I think it would be easy to test. Recommend setting up a simple jar testing bench scale treatability study. Easy and inexpensive, and will provide you with information on the required dosing of hydrated lime for this application. If you try it, please let me know what you find out.

thanks for the post,

Thanks for the reply.
I am providing consultancy for septage management for 6 cities in Rajasthan State in India, supported by ADB. I am providing unplanted or planted sand filter beds (depending on site condition) followed by treatment options for effluent. I am not recommending lime due to its recurring expenses and precautionary measures required during handling by semi-skilled workers at the sites. Moreover, in the State, atmospheric temperature goes up to 500 C, sufficient to kill pathogens on drying beds. If frequency of loading is decreased by increasing number of beds and maintaining the sludge height of 20 cm, dried solid mass of desired level can be obtained with least chance of survival of pathogens.
Effluent from filter beds has high BOD – around 500 mg/l. It’s challenging to treat it to the acceptable level of discharge or reuse. Lagoon is not suitable to meet the discharge norms. Moreover, it requires large space- not normally available in urban areas. Anaerobic system is also not suitable to meet the discharge norms. I will use aerobic system with bacterial growth media. Lime is also not suitable as in such case population density of bacteria in effluent will definitely reduce, resulting in lower efficiency of the treatment system.
One simple suggestion-- Is it possible to use lime with higher doze in the septage only during the last loading of the filter bed? In such case lime will kill pathogens in solids on filter bed. Earlier effluent will have normal population density of bacteria. Effluent of last day will have little volume, of course with higher level of lime concentration. But total concentration will be much lower with little or no change in pH.

Thanks for your questions. First it is important to know that lime stabilization will not eliminate all of the pathogens, but certainly most of them. Also, it is more accurate to say that the process limits regrowth of bacteria, and not that there will be no regrowth. We don't want to over-sell the technology.

It is a good question about the ABR function. From our experience, the use of the ABR after the lime stabilization process functions more as a mechanism for additional physical separation for whatever solids remain in the wastewater stream after the sand filtration, where the bulk of the suspended solids are removed. The ABR also provides detention time of between 1 and 3 days which allows the pH to drop to a level more suitable for subsequent treatment, such as the constructed wetlands.

As for the term "stabilization", it has actually been used for years. The US Environmental Protection Agency utilized it back in 1978 in their "Full Scale Demonstration of Lime Stabilization" document that looked at different application rates of hydrated lime for wastewater, return activated sludge, and septage. I would suspect that there actually is some degradation of the biosolids that occurs from the reaction of hydrated lime and sludge.

Thanks again for your comments. Please advise if you are planning any trials. I just returned from Myanmar where Oxfam has demonstrated a full scale system serving more than 50,000 people. We are also trying it on a much smaller scale using the in-pit lime stabilization process first trialed by iDE in Cambodia. Seems to have really good potential there.

The topic is much relevant for many countries. There are several papers/ guidelines in different countries, highlighting use of lime stabilization for sepatge management. I have a few queries:
i. Application of lime to increase pH to12 will definitely eliminate pathogens, other bacteria and helminths from septage. The Implementer's Guide of USAID also mentions that there is no chance of re-growth of bacteria when treated with Lime. It also mentions that after passing septage through sand filter bed, effluent should be treated through ABR technology.
ii. Now the simple query arises how a biological treatment system like ABR would function for the treatment of effluent having such high pH and without presence of bacteria in the system ( bacteria are already eliminated by using Lime).
iii. The Guide uses terminology— Lime stabilization. I think function of lime is only to eliminate bacterial and other pathogens. It never results in stabilization of organic matters. Stabilization is a completely different term from pathogen free environment.
I’ll be happy to have response from you and other members of the Forum.

Sorry for the slow reply.

Here an update from the SEEK project (www.sandec.ch). The SEEK project researches processing of faecal sludge into fuel pellets and electricity through gasification (in Kampala, Uganda). Data collection of this project is still ongoing, this is what we learned so far:
  • The Bioburn pelletizer is an appropriate technology for pelletizing of faecal sludge. It works well and is ready for full-scale implementation. Dewatered faecal sludge (for example from a drying bed ) can be pelletizer at a moisture content of 40-60%. Please contact me if you are interested in the technology. Our partner Bioburn is currently working on product brochure.
  • Faecal sludge can also be co-pelletized with other biomass to increase endproduct quantities and reduce the ash content of the fuel, for example, with coffee husks or sawdust. However, this may require a binder (depending on the ratio of dewatered faecal sludge and biowaste, and the type of biowaste).
  • The big advantage of faecal sludge in a pellet form is that it can be dried much faster compared to faecal sludge on a drying bed. Therefore, it is of benefit for energy recovery of dried faecal sludge, for example, in cement or clay industries. Pellets are also favorable for storage and transport.
  • This said, our market research did not identify (yet) a company with a demand for a fuel in a pellet form. Schools could use pellets to meet their energy need (e.g. for cooking), however, the commonly do not have appropriate control of emissions. Industries (e.g. clay and cement industries) require powdered/crushed fuels.
  • Gasification of the faecal sludge pellets with the All Power Labs gasifier (www.allpowerlabs.com) and Husk Power Systems gasifier (www.huskpowersystems.com ) available to the project was not successful. We think that this is due to the high ash content. Also faecal sludge pellets mixed with sawdust or coffee husks could not be gasified.
  • According to correspondence with All Power Labs, their new model will be able to use dried faecal sludge as a fuel. Apparently CARLA international is also working on gasification of faecal sludge but we could not establish a contact to exchange knowledge (yet).
  • In Europe and the US, large scale (> 1 MW) are available for waste gasification (for example of dewatered wastewater sludge). Companies include: Xylowatt (www.xylowatt.com/) or ProCone (www.procone.org) . Xylowatt analysis our faecal sludge pellets in their laboratory and their results suggest that gasification of faecal sludge with their technology is possible. However, the manufactures and the project agreed that the capital , operation and maintenance requirements are too high for sustainable operation in Sub-Saharan Africa.
  • Following the not so good results from gasification we are currently gearing our research more towards pyrolysis of faecal sludge. There were several articles and video on the magic of carbonization and how it will make us rich, have sustainable FSM and save our forest (see below). We would like to add a bit of evidence to this.
edition.cnn.com/videos/world/2016/02/24/...p-sanitation-spc.cnn

www.monitor.co.ug/artsculture/Reviews/Lu...fp3apuz/-/index.html


  • In the remaining project period we will also work on geotubes and geobags for faecal sludge dewatering. Geotubes have been tested for faecal sludge (for example in Malaysia) to reduce transport distances for vacuum trucks. However, recommendation of treatment operators are not really available. We would like to support this to work towards implementation of this technology.
We would be very happy to get feedback from you on our work.

For example: Do you think industries in your city/country require an industrial fuel in a pellet form?

Thanks.

Behaviour change materials and experiences related to FSM - by: GOALSierraLeone http://forum.susana.org/forum/categories/53-faecal-sludge-management/17625-behaviour-change-materials-and-experiences-related-to-fsm#17625 http://forum.susana.org/forum/categories/53-faecal-sludge-management/17625-behaviour-change-materials-and-experiences-related-to-fsm#17625 forum.susana.org/forum/categories/99-fae...rprises-phase-2-goal ) we are currently planning and designing for our social marketing and behaviour change interventions.

Issues to be tackled are around generally raising the awareness of the public on FSM issues, discouraging people from disposing solid waste in their pit latrine, discourage practices of illegally burying/disposing faecal sludge locally, increase acceptance of FS transfer stations, disseminate information about new services available and regulations to be enforced, etc.

When searching (on SuSanA and more broadly on the web) for existing material on behaviour change campaigns specifically related to FSM, we found only very limited information. On this discussion (forum.susana.org/forum/categories/71-beh...tion-bangladesh#7194), BCC materials for FSM in Bangladesh are mentioned, but no more detailed documents or links are made available.

It seems like most BCC materials available are more generally for WASH issues (or other topics), but very little specific for FSM.

Does anyone have any experiences, recommendations or documents to share on behaviour change & communication / social marketing issues related to FSM?

Thanks for showing interest in our SaniPlan - IFSM toolkit.

We are in discussions and working together with AIT for development of FSM toolbox and for integrating SaniPlan-IFSM toolkit in the overall IFSM Tolbox being developed. AIT team is reviewing the possibility of internalizing the tool as a part of the FSM toolbox.

The SaniPlan is a comprehensive model which was prepared based on our experience under the PAS Project. It is a tool for citywide WSS planning. SANIPLAN, has been used for preparation of several City Sanitation Plans in Maharashtra by the CEPT team. It has also been used by other agencies in India. (SaniPlan link : www.pas.org.in/Portal/document/Resources...s/Tool_SANIPLAN.xlsm )

SANIPLAN has been adapted for IFSM planning. For this purpose, CEPT has developed a web based toolkit (Toolkit link : sites.google.com/site/pasprojectifsmguide/ )

We are happy to have another version of our tool - now called SANITECH (open to better names:-)
The tool enables user to identify suitable systems for a city/ward/area, allow user to create scenarios through different interventions and compare scenarios.

The final version will allow the user to create their own systems, and will have indicators to assess the different scenarios. Please log in as a demo user and you can see the functionalities. The manual is at the upper right end of the interface.

Please send in your feedback. This will be one of the tools as part of the FSM Toolbox (developed by AIT, Bangkok). The main intent of the tool is to propose relevant technologies (considering the whole SVC), suited to the constraints of the city/ward/area. The tool also has a repository of sanitation systems. Please feel free to send us cost and performance numbers of the systems that you might be familiar with, along with any new tested technologies- so that we can modify our database accordingly.
