Drainage sewage treatment plant
Drainage treatment plants
they consist of two basic elements: Septic tank is the basic device occurring in all technological systems in which the first stage of purification is performed (ie the so-called anaerobic pretreatment). It is followed by preliminary treatment of sewage. Impurities heavier than water fall to the bottom (sediment) and decompose in anaerobic digestion, lighter they float to the surface and form a sheepskin (flotate). As a result of the processes occurring, mainly floating contaminants and suspensions are removed from the sewage, as well as organic compounds. Drainage drainage is a system of underground perforated drainage pipes (drains) introducing into the ground sewage pre-treated in a settling tank. Wastewater, flowing through successive filtration layers of gravel and sand (laid under drains), decomposes in biological oxidation processes, with the participation of microorganisms.
