Flow & Load Equalization Before the Settler
Buffering Peaks for Stable Clarification
Plate settlers perform best at a steady hydraulic and solids load. An upstream equalization tank absorbs peaks and protects effluent quality.
Industrial and municipal flows are rarely constant — batch discharges, shift patterns, and storm events create surges in both flow rate and solids concentration. Because a plate settler is sized around a design surface loading rate, sudden hydraulic peaks can push solids over the plates and into the effluent.
An equalization basin upstream buffers these swings, delivering a near-constant flow and concentration to the coagulation and settling stages. This stabilizes chemical dosing, improves floc formation, and produces consistent effluent quality.
Where space or budget rules out a large basin, R+F can specify a settler with sufficient hydraulic margin or a modular configuration that tolerates variable loading.
Engineering Considerations
Peak Attenuation
Sizing the basin to the diurnal or batch profile smooths both flow and solids load.
Dosing Stability
Constant flow lets coagulant dose track load accurately, improving floc quality.
Mixing
Gentle mixing keeps solids in suspension and homogenizes the stream without shearing pre-formed floc.
