Types of septic tanks

Cleaning household water can be carried out by several types of treatment facilities. The first of them is a simple septic tank. At the initial stage, water cleaning occurs, it is carried out in a special tank — septic tank. Cleansing occurs as follows: all particles that are contained in water are settled in the form of sediment, part from it dissolves in water over time, and some settles at the bottom of the septic tank in the form of solid mineral particles. A fat film is formed on the surface of the water at this time. That is, during preliminary cleansing, the fluid from solid particles occurs. Water is cleaned by about 65-70%.
