FERTIRRIGAÇÃO COM ESGOTOS TRATADOS POR PROCESSOS ANAERÓBIOS E PÓS -TRATAMENTO Ciências Agrárias
Santos, Roberto Jose dos; Fortes Neto, Paulo; Batista, Getulio Teixeira.
Citação: SANTOS, R. J. dos; FORTES NETO, P.; BATISTA, G. T. Fertirrigação com esgotos tratados por processos anaeróbios e pós –tratamento. Repositório Eletrônico Ciências Agrárias, Coleção Ciências Ambientais, <http://www.agro.unitau.br/dspace>. p. 1-10, 2011. Resumo. Este trabalho foi desenvolvido a partir de pesquisas de artigos científicos de experimentos efetuados na cidade de Campina Grande, com esgotos domésticos, tratados inicialmente por reatores anaeróbios do tipo UASB e posteriormente submetidos a diversos tipos de pós- tratamentos, em todas as experiências avaliou-se a eficiência de cada sistema, buscando-se verificar basicamente, alguns indicadores tais como: remoção de nutrientes, organismos patogênicos, eficiência de DBO, DQO, sólidos...

Urban wastewater: A valuable resource for agriculture - A case study from Haroonabad, Pakistan AgEcon
van der Hoek, Wim; Ul Hassan, Mehmood; Ensink, Jeroen H.J.; Feenstra, Sabiena; Raschid-Sally, Liqa; Munir, Sarfraz; Aslam, Rizwan; Ali, Nazim; Hussain, Raheela; Matsuno, Yutaka.
Farming communities in water-scarce regions increasingly practice the use of urban wastewater in agriculture. Untreated urban wastewater is generally considered unacceptable for direct use because of potential health risks. However, in many parts of the world, poor farmers in peri-urban areas use untreated wastewater. This situation is considered likely to continue even in the foreseeable future due to the high investment cost associated with the installation of treatment facilities.

Utilisation des chaînes alimentaires naturelles et du recyclage des eaux usées dans la production à grande échelle de juvéniles pour l'aquaculture ArchiMer
Barbabé, G..
The production of Juveniles, key of aquaculture, needs for the alimen­tation of the larvae, to dispose plankton preys, which cannot be supplied by rea­ring. The collections realised with adapted implements, have led to very po­sitive results In both types of media, situated in the surroundings of Séte : mar shes and oxydation ponds (used for waste water purifying). The most abundant plankton in these two kinds of media are uni-cellular algae, Rotlfera, Copepoda, Daphne (oxydation pont) and Aetemia (marshes). These populations constitute a complete alimentation sequence without an equivalent for the necessities of larvae and juveniles. Our qualitative collections (from 0,2 to 20 kg/h) plankton, dependent on the species) have allowed to rear, without any...
