Grey Water Treatment - Waste Water Treatment Plants
Grey water is collected separately in an underground tank. A screen of 10 mm opening is provided at the inlet of the tank to remove the large suspended particles / debris from the waste stream. Aeration is given to ensure that septic conditions do not occur. The grey water is then pumped to the aeration tank by using a submersible pump having cutter mechanism. This will reduce large sized particles to less than 2mm size. In the aeration tank, chlorine is added to ensure chemical treatment of the waste water. Aeration of the waste stream not only ensures aerobic conditions, but continuous mixing of the effluent.
