In pre-treatment plants, water is required for the proper cleaning of pollutants and the removal of suspended solids and colloidal substances before the wastewater reaches the sewage treatment plants. The right amount of water and its quality are important to ensure the effectiveness of the pre-treatment process and prevent damage to plant components.
To ensure the highest quality of the influent water, the use of gravity alone is insufficient, especially in the case of non-sedimentable material, often of a colloidal nature. Conventional clarification is therefore used - an effective technique that combines coagulation, flocculation and sedimentation to quickly remove suspended substances (turbidity).
