PROPOSAL FOR A LOW COST WATER TREATMENT SYSTEM BY MEANS OF CHLORINATOR WITH TABLET

Abstract

The supply of water by supply services is essential to promote the quality of life of the population, but the disorderly growth of cities has not accompanied the evolution of the infrastructure for adequate service. As a result, low attendance makes it possible to consume contaminated water and transmit diseases, which requires alternative treatment techniques. Thus, the objective of this work is to evaluate the performance of water treatment using a tablet chlorinator in order to achieve adequate potability standards. The work was developed by carrying out a performance study of water treatment with the adoption of a tablet chlorinator. To support the research, a device was assembled with low-cost materials and easy to obtain parts and then tested the hydraulic operation and the standard of treatment. The analyzes raised in question were chlorine, thermotolerant coliforms, pH, conductivity and dissolved oxygen. It was verified that the prototype presented a good performance regarding its functionality in relation to tightness, flow performance through the regulation of the system. It was verified that the opening of valves altered the concentration of effluent chlorine to the system, thus it was verified that the angle with an opening of about 30° improved the quality of the effluent water. This positively influenced the concentration of diluted chlorine in the water, keeping it microbiologically safe, pH within acceptable standards for potability and residual chlorine of 3.0 mg/l, confirming the effectiveness of the system.
