The treatment of water by physicochemical (primary) means the mixing of the water and its aeration, but also its clarification (settling). The most common physicochemical water treatment process is the flocculation-coagulation technique, which consists of mixing coagulant products with water, the property of which is to collect in solid clusters the materials in suspension in the water, which makes it easier to collect them. The techniques for separating the flakes or clusters thus coagulated or flocculated are most often filtration, settling down the basin (by gravity), or aero-flotation (sending jets of air which collect the particles at the bottom. surface of the water).
ETE offers you a complete range to successfully complete this treatment step (Coagulants, flocculants, settling tank, dissolved air flotation device (DAF), aero-flotation device, etc.)
