Resumo
The 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 treatment
