SANITARY STANDARDS AND REAL-WORLD ANALYSIS OF DRINKING WATER HYGIENE

Аннотация

Water is one of the most important factors necessary for human life. 60-70% of the human body is water, and its purity, safety and hygienic condition are of direct importance for health. Therefore, the hygiene of drinking water, its compliance with sanitary standards, the degreeof purification and the current real state are considered an important socio-hygienicissue. Water purification is a set of technological processes designed to bring the quality of water entering the water supply network from water supply sources such as rivers, lakes, ponds, reservoirs, etc. to the established standards. It also includes the treatment of wastewater from industrial enterprises and household enterprises. It is carried out using water supply and sewage treatment plants, as well as using biological and chemical engineering structures at enterprises, and usingbiological and chemical methods.
