WATER TREATMENT STATION
An Water Treatment and wastewater has the function of removing impurities and contaminants present in it, so that it can be reused for other purposes, such as cooling towers, floor cleaning, among others.
The reuse of industrial water is a very beneficial process in several senses, because the effluents will be discarded by the company according to the required by state and federal laws. In addition, the reuse of water that passes through an Water Treatment and wastewater will make the company save water resources, contributing to both the preservation of the environment and an economy for the company.
PROCESSES OF WATER TREATMENT STATION
In this stage, the Water Treatment Station groups in coagulant action the impurities present in the water, in larger particles, that when they go through the decanting process can be removed. These used reagents – which are usually Aluminum Sulphate and Ferric Chloride – can be called coagulants.
The flakes formed are separated from the water by Water Treatment and that occurs from the action of gravity in the tanks.
The decanted water on Water treatment station is forwarded to the filtering units. At that moment, a filter developed in a granular porous medium, installed on a drainage system, retains and removes impurities remaining in the water.
The disinfection of waters held in Water Treatment occurs through a physical or chemical agent. So, it turns out the destruction of pathogenic microorganisms. The disinfectant agents used are usually chlorine, ozone, ultraviolet light and silver ions.
Water fluoridation held in Water treatment station, is made from fluoride-based compounds. Applied in water, This compound reduces the incidence of dental caries by up to 60%.
