Phosphorus Removal
Chemical Phosphorus Precipitation & Plate Settler Clarification
Achieve phosphorus discharge limits below 0.5 mg/L with chemical precipitation followed by high-rate plate settler clarification.
Phosphorus Removal
Phosphorus removal from wastewater is increasingly regulated to protect receiving waters from eutrophication. Chemical phosphorus removal — using iron or aluminum salts to precipitate dissolved phosphate — is one of the most reliable methods for achieving low discharge limits.
The precipitated phosphorus forms fine floc particles that are efficiently captured by plate settler clarification. The high surface area provided by inclined plates ensures effective removal of even small precipitate particles, achieving total phosphorus levels below 0.5 mg/L.
R+F plate settler systems for phosphorus removal include integrated chemical dosing, flash mixing, flocculation, and high-rate clarification in a compact, pre-engineered package.
