process and installation for grit removal and effluent water treatment chemical

摘要

gross flow water is normally introduced into a processing dessableur (2) for connection to separate grit removal, flow dessable and sand.at other times, such as rain or high water demand, we introduced a clotting agent, sand, ballast and a flocculant.the flow is passed through a coagulating area (14) of maturation and with substantially all the sand and the colloid particles agreges or, in the dessableur.or would such as decante effluent and sludge that is evacuated with colloid particles and sand extraction and agreges and evacuated by the extraction means (22).the way out of sand (51) of the dessableur; collecting sludge, we separated (54.63), the sand ballast for recycling in the injection zone of sble and pull the excess sludge and sand
