Two ADPL systems were installed on residential plots with 17 and 35 residents in a peri-urban area outside of Eldoret, Kenya. Each system comprised three toilets built above a floating dome digester and one heat pasteurization system to sanitize the digested effluent. ADPLs are simple systems, with no moving parts and relying on gravity-induced flows. Adoption at the two sites was successful, and residents reported that the systems had little to no odor or flies. ADPLs were monitored for biogas production and temperatures in the pasteurization system. ADPLs serving 17 and 35 residents produced on average 16 and 11\u2009L\n                    <jats:sub>biogas<\/jats:sub>\n                    \/person\/day (maximum of 20 and 15\u2009L\n                    <jats:sub>biogas<\/jats:sub>\n                    \/p\/d), respectively. The temperature in the sterilization system was greater than 65\u00b0C on 58% and 87% of sampling days during the most stable period of operation. Treated effluent was analyzed periodically for chemical oxygen demand (COD), biochemical oxygen demand (BOD), total ammonia nitrogen (TAN), pH, and fecal coliform (FC). On average, the effluent at the two locations contained 4,540 and 6,450\u2009mg COD\/L (an 85% or 89% reduction of the estimated input), 2,050 and 3,970\u2009mg BOD\/L, and 2,420 and 4,760\u2009mg NH\n                    <jats:sub>3<\/jats:sub>\n                    -N, respectively, and greater than 5\u2009log reductions of FC (nondetectable) in the sterilization tank. Results from this field study show that anaerobic digestion of minimally diluted fecal sludge can provide enough energy to pasteurize digester effluent and that the ADPL may be a suitable option for on-site fecal sludge treatment.\n                  <\/jats:p>","DOI":"10.1089\/ees.2016.0148","type":"journal-article","created":{"date-parts":[[2016,8,11]],"date-time":"2016-08-11T15:41:43Z","timestamp":1470930103000},"page":"898-906","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":41,"title":["On-Site Fecal Sludge Treatment with the Anaerobic Digestion Pasteurization Latrine"],"prefix":"10.1177","volume":"33","author":[{"given":"Aaron A.","family":"Forbis-Stokes","sequence":"first","affiliation":[{"name":"Duke University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick F.","family":"O'Meara","sequence":"additional","affiliation":[{"name":"Wataalamu Repair & Maintenance","place":["Kenya"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wangare","family":"Mugo","sequence":"additional","affiliation":[{"name":"University of Eldoret","place":["Kenya"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gelas M.","family":"Simiyu","sequence":"additional","affiliation":[{"name":"University of Eldoret","place":["Kenya"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc A.","family":"Deshusses","sequence":"additional","affiliation":[{"name":"Duke University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2016,8,11]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"publisher","DOI":"10.1021\/es304284f"},{"key":"e_1_3_3_3_1","unstructured":"Bill and Melinda Gates Foundation (BMGF).
