Experiments were performed  in two pilot plants. The first pilot plant was a  UASB reactor installed after a conventional full- scale sedimentation tank. The second pilot plant was  a two-stage UASB system with post-treatment in five  waste stabilization ponds (WSP) in series. Both  systems studied were highly robust and efficient.  They consistently delivered a final effluent in  compliance with discharge standards, and produced a  small amount of well-stabilized sludge. The  performance of the systems was not affected during  the coldest period of the year, which lasts about  three months. A single-stage UASB reactor followed  by a series of WSP could be a very efficient and  simple system for the treatment of raw sewage in  subtropical regions. More sustainable sanitation  requires not only appropriate technologies, but also  a fully democratic way of technology selection.  Political and economic motivations need to be  acknowledged but, at the same time, environmental  problems and social injustices must be solved.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838368665\"\u003e\u003ch3\u003eAnaerobic treatment of domestic wastewater in subtropical regions\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838368665","offer_id":39499040260189,"sku":"9783838368665","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/2163dce2-10e0-4160-98ed-284b8bb184ab.jpg?v=1759211112","url":"https:\/\/shop.autorenwelt.de\/products\/towards-more-sustainable-sanitation-systems-von-lucas-seghezzo-und-gatze-lettinga","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
