HWE High Rate Solid Contact Clarifiers
A high-rate treatment plant in a single basin that employs the principle of internal slurry recirculation provides effective clarification in municipal or industrial water and wastewater applications.
- Constructed in either a steel tank or a concrete basin.
- A unique rotor-impeller combination has made it possible to control mixing and slurry recirculation to accommodate changes in water characteristics.
- Sludge scrapers and bottom sumps accommodate unusually heavy amounts of sludge.
High-rate solids contact clarifier combines optimized flocculation, internal and external sludge recirculation, to achieve very high hydraulic loading and treatment efficiencies. It is effective for lime softening of ground or surface waters, tertiary treatment of wastewater, and precipitation of metal hydroxides from waste streams. It can accommodate a wide range of flow rates and solids variations. •The space requirement is usually 50% the size of a comparable clarifier.
- The unit produces a very dense sludge that minimizes sludge handling.
- Rapid sludge settling and thickening.
- Minimum Operator attention.
