Emprego da filtração simples como meio de melhoria das características físico-químicas da água de poços em Campina Grande - PB.

Abstract

The situation of water scarcity experienced in recent years in the city of Campina Grande - PB, motivated the use of alternative sources to meet the demands, and the abstraction of groundwater is one of the sources used. The present study analyzed the physical and chemical properties of water from three wells in the Catolé and Jardim Quarenta, neighborhoods in Campina Grande. The objective of this research is to verify the behavior of pH, turbidity, electrical conductivity, total hardness, calcium - related hardness, total solids and total coliforms of the water of these wells from the treatment by chlorination and filtration. The filter used in the research was handcrafted for this purpose. The results showed significant improvements in the quality of such parameters with the use of the filter. In well 1 there was a turbidity reduction of 19.32%. In well 2 there was an increase of ph in 25.68%. In well 3, the turbidity reduction was 98.46%. Therefore, it can be said that such improvements in the parameters allow the use of groundwater for several other less demanding purposes, such as agricultural use and industrial use.
