Physical and chemical control of fresh water for consumption and industrial use: system of treatment, analysis methods and legal parameters

Abstract

The aim of this study was a literature on the physical-chemical analysis of water supply and sewage, highlighting the importance of water and its quality of life for the maintenance of the supply system for drinking water and its treatment until the actual performance of physical-chemical analyzes of interest to government agencies. The execution of laboratory tests for the control and surveillance provide an indication of its quality, assisting in the verification and monitoring of standards by the federal government, state and municipal-based legislation. When selecting technology and treatment system is vital that all information about the source of water is collected. This is important to know how the water behaves before attempting to establish the system of treatment. Similarly, it is essential to implement a program for monitoring the Water Treatment Station, in order to evaluate each stage of treatment with regard to their effectiveness and efficiency. The characteristics of drinking water vary, being of great importance to the analytical methodology for determination of physico-chemical parameters that assess these properties and specifications must meet national standards. Therefore, before choosing the method, one must know the nature of water and set what you want to analyze in order to have satisfactory results.
