🌊 Circular Clarifiers (HRT 2.0-4.0 Hours), Surface Overflow Rate SOR GPD/SqFt

Industrial Wastewater Clarifier HRT Calculator

Size industrial primary and secondary settling clarifiers under Ten States Standards: calculate Hydraulic Retention Time (HRT hours = Volume / Flow), Surface Overflow Rate (SOR 400-800 GPD/sq ft based on floc settling velocity), peripheral weir overflow loading rate (GPD/linear ft), and wastewater treatment EPC bidding.
