Tertiary Treatment
Advanced Polishing for Stringent Limits
Plate settlers polish secondary effluent, removing residual solids and phosphorus to meet stringent discharge and water reuse standards.
Tertiary Treatment
Tertiary treatment removes residual suspended solids, turbidity, and nutrients that remain after secondary treatment. It is required where discharge permits are strict or where effluent is reused.
Plate settlers, often combined with coagulant and polymer dosing, capture the light residual and chemically precipitated flocs typical of tertiary streams at high throughput.
Used ahead of filtration and disinfection, tertiary plate settlers stabilize effluent quality and reduce downstream fouling, supporting reliable compliance and reuse.
