This paper presents information, data and conclusions based on two pilot studies investigating high-rate clarification on an industrial wastewater application and a drinking water application. Pilot Study 1 tested a secondary effluent wastewater source from an industrial paper mill for the treatment of phosphorus to less than 0.10 mg/L effluent. Pilot Study 2 was completed on a groundwater source with relatively high hardness (320 – 330 mg/L as CaCO3) under a caustic softening treatment process. Both pilot studies demonstrated the effectiveness of the high-rate clarification process for treatment of varying and challenging water quality conditions for common treatment applications in both water and wastewater areas.
