Aplicabilidade do lodo da eta para o tratamento do efluente doméstico no Município de Palma Sola - SC

Abstract

The planet has limited resources, one of which is water, indispensable for life and used in different ways, some of which require that this resource pass through a treatment plant, an enterprise responsible for processing the water, delivering it to the consumer in the standards required by the legislation, being considered potable. The municipality of Palma Sola is located in the extreme west of Santa Catarina state, on the border with the state of Paraná, with approximately 7,500 inhabitants. Where a water treatment plant was created to combat the drought, in the Linha Brasil community, in the interior of the municipality, serving approximately 54 homes, after the process the removed dirt is sent to a stabilization pond, where the water evaporates and only the solid waste. This residue is known as sludge, having chemical products, thus requiring care for its destination. The objective of this study was to determine at different concentrations the feasibility of recycling the sludge generated by the water treatment, to use this sludge to assist in the treatment process of the effluent treatment plant in the Municipality of Palma Sola and to make comparisons between the generated compost and the commercial coagulant. The sludge was calcined and used in the jar test, the result of this process led to an increase in turbidity, a result that demonstrates that the methodology used was not effective for reduction, requiring further studies for its use.
