Polishing Treatment
Final-Stage Clarification for Stringent Limits
Plate settlers act as an effective polishing stage, removing residual solids and turbidity to meet the tightest discharge and reuse standards.
Polishing Treatment
Polishing treatment is the final clarification step that removes residual suspended solids, turbidity, and associated nutrients after primary and secondary processes. It is essential where discharge permits or reuse standards are strict.
Plate settlers make an excellent polishing stage because they capture the light, low-concentration flocs typical of tertiary streams at high throughput, often combined with a small coagulant dose.
Used ahead of filtration or disinfection, a polishing plate settler stabilizes effluent quality and reduces load and fouling on downstream equipment.
Key Benefits
Tight Compliance
Meets stringent tertiary discharge and reuse standards.
Stabilizes Effluent
Buffers residual solids from upstream process upsets.
Protects Downstream
