Abstract

Recent events related to the lack of water in Brazil demonstrated that the reuse of water is an issue that needs to be explored. In the present study, research was conducted to determine a source of domestic water that can be treated and reused with simple equipment, produced by national industry, or available in the domestic market. It was selected the treatment of the bathwater from the shower. The results of the parameters analyzed, pH, conductivity, color, turbidity, COD, phosphorus, total suspended solids, oil and grease, bacteria, total nitrogen, ammonia nitrogen, and total coliforms indicates that the model used needs adjustments, odor removal, and optimization of the effluent residence time in the treatment tank. Corrected these inconsistencies the system could be converted into a product for domestic use in regions where there is a shortage of water.
