Caracterização de resíduo de ETA visando sua disposição na saída de lagoas de estabilização. Revista Monografias Ambientais, Santa Maria, v. 14,n. 2, p. 3154-3263, mar. 2014.e- 2236-1308http://repositorio.bc.ufg.br/handle/ri/14546The WTP are responsible for the production of drinking water to be consumed by the population, which generates social benefits, however, as in any manufacturing industry, waste is generated and there is the need to dispose them properly without harming the environment. The solid waste management included waste destination and for this stage is necessary to know the waste characteristics in order to define the best treatment and disposal. This study aimed to characterize the WTPS produced by a WTP in the state of Goiás, Brazil, that employs in their treatment the coagulant aluminum sulfate. Physico-chemical analyses and structural properties were verified, showing that the residue consists of clay (mainly the mineral kaolinite and halloysite), silt and sand. The residue was determined as not plastic. The EDS analysis detected the presence of aluminum, which is related to the phosphorus removal in water and sediment, which facilitates their reuse in the wastewater treatmentporAcesso AbertoDescarga de decantadorEstação de tratamento de águaLamaLodoResíduoDischarge of decanterWater treatment plantMudSludgeResidueArtigo10.5902/2236130812399
