The Toilet Board Coalition brings together some of the most forward-thinking organisations in the sanitation space: Firmenich, Kimberly-Clark, LIXIL Corporation and Unilever represent the business sector; Dr Val Curtis of the London School of Hygiene & Tropical Medicine and Barbara Evans of the University of Leeds bring academic rigour to the table; and a number of development sector and governmental bodies bring their one-of-a-kind resources and specialist knowledge: Agence Française De Développement; the Asian Development Bank; the UK’s Department for International Development; Stone Family Foundation; WaterAid; Water and Sanitation for the Urban Poor (WSUP); Water Supply & Sanitation Collaborative Council (WSSCC); the World Bank’s Water and Sanitation Programme; the World Toilet Organization; Water and Sanitation for Africa; and UNICEF.
- Re: Nice and quick overview about constructed wetland's historical developments, by David AUSTIN, USA - by: F H Mughal December 21, 2014That is a nice brief publication on wetlands' history. I think, USEPA has been instrumental in the use of wetlands. The attached publication, a joint publication of National Oceanic and Atmospheric Administration, Environmental Protection Agency,Army Corps of Engineers, Fish and Wildlife Service, and Natural Resources Conservation Service, is a guide on […]
- Re: Pathogen concentration in untreated fecal sludge - by: SusannahSoilet December 21, 2014I wonder if we need to take a step back from 'counting pathogens' and look at the 'overall transmissibility and outcome of exposure' to these biological entities. For a pathogen/parasite to successfully infect a new host through fecal sludge, it must surmount several steps: 1: gain contact 2: retain infectivity - i.e. have enough vitality […]
- Re: Closed loop recycling of flush water through ABR and Constructed Wetland? - by: canaday December 21, 2014Dear Dennis and Detlef, Dennis, the idea would be to treat this blackwater just as well as if we were dumping it into the environment, only never dump it into the environment, so maybe somewhere between 0 and 200 fecal coliform bacteria per 100 ml. It would be key to eliminate any smell or color, so users do not enough notice the difference. Detlef, thanks f […]
- Re: Pathogen destruction in biogas plant vs ABR (Anaerobic Baffled Reactor) - by: KeithBell December 20, 2014Other than clostridium botulinum, another pathogenic clostridia of concern in biogas is clostridium perfringens. High concentration of Clostridium perfringens found at 45 days reveals a risk to use the digested slurry on the arable land. Some Clostridium spp. may cause infection in animals e.g. blackleg (Clostridium chauveoi), malignant (Clostridium septicum […]
- Re: Pathogen destruction in biogas plant vs ABR (Anaerobic Baffled Reactor) - by: muench December 20, 2014Keith, I was actually going to post the same thing as Christoph, but he was faster. The suggestion I would make to you is this: If you want to bring up the botulism issue again in a new thread, please be so kind to include in your post a link to the earlier discussion (you are right, Dan-Eric might have missed it, which is why you should have pointed it out; […]
