High Rate Solids Contact Clarifiers (HRSCC) are next generation technologies that achieve higher throughput in a smaller footprint than conventional clarifiers - resulting in cost savings and improved performance. The design features of the solids contact type clarifier provide the three zones necessary for proper clarification: Rapid mix zone, where raw water, recirculated precipitates and fresh reagents are rapidly mixed together. Slow mix zone, where gentle mixing permits floc formation and brings the floc into intimate contact with the suspended impurities. Clarification or settling cone, where the upward flow (rise rate) is reduced to a low value to permit the precipitation to settle out. This ensures a higher clarified water quality and greater tolerance to variations in inlet conditions. Our company is involved in producing HRSCC, which is very reliable and cost-effective.
