Subject: Living technologies for waste water treatment Date: Wed, 13 May 1998 15:29:05 +0200 Encoding: 42 TEXT Sender: owner-infoterra@cedar.univie.ac.at Reply-To: Jacky FooStatus: R Announcement of an Internet paper discussion On 11 May to 5 June 1998, the discussion on a paper entitled "The design of living technologies for waste treatment" and information available at Living Technologies home page (http//:www.livingmachines.com) with John Todd & Beth Josephson of Ocean Arks International (Falmouth, USA) will be conducted via a LISTSERV mailing list. The paper has been published in Ecological Engineering, 6:109-136 and available at http://home2.swipnet.se/~w-25860/icibs/toddl.html.dex.htmlh.cfmenbul-e.HTM . This article elucidates the emerging principles required for the design of task-oriented mesocosms. Twelve key factors are discussed including mineral diversity, nutrient reservoirs, steep gradients, high exchange rates, periodic and ramdom pulses, cellular design and mesocosm structure, subecosystems, microbial communities, photosynthetic bases, animal diversity, biological exhanges beyond the mesocosm, and msocosm/macrocosm relationships. The fields of ecological design and engineering are developing efficient living technologies for environmental repair, waste treatment, food production and infra-structure integration. A living machine for the treatment of sewage and the production of fish and horticultural products, operational since 1989, produces high quality water irrespective of season or input variation. BOD5, COD, TSS, nitrification, phospohorus uptake, metals sequestering and coliform reduction data depict a robust, self-organizing technology capable of handling the mixed waste stream of a New England industrial city. This paper discussion is arranged by the Inst of Advanced Studies of the United Nations University (Tokyo) and UNESCO Microbial Resources Center (Stockhokm) for the Internet Conference on Integrated Biosystems (ICIBS) (http://home2.swipnet.se/~w-25860/icibs/prog-reg.htmex.htmlh.cfmenbul-e.HTM).
