Automatic Polymer Preparation Unit

Flocculation is an essential stage in the treatment of sludge coming from municipal or industrial wastewater treatment plants. In these processes, polymeric flocculating agents are used to enhance the treatability of the sludge. Flocculants, with their very high molecular weights (long chains of monomers) and their different ionic charge, mixed with water and fix the destabilized particles on their chain. Therefore, the particle size in the aqueous phase will increase throughout the flocculation step with the formation of flocs. The structure of flocs induces a release of the water. This water will thus be easily eliminated during the thickening and dewatering step. Flocculants are also used for other industrial solid-liquid separation applications, such as in chemical industries, petrochemical plants, pulp and paw plants, food industries and others. With many years of successful experience in water and wastewater treatment industries, Hydro System Supply has developed polymer make-up and dosing plants which adapted to the above-mentioned processes. A combination of three tanks contributes to the continuous and automatic preparation process, easy operation, convenient maintenance, thus the significant reduction of labor cost.
