Removal of phosphorus from wastewater

On this page, you’ll discover how and why removal of phosphorus from wastewater and phosphorus recovery is preferred worldwide.

Phosphate removal

Phosphorus removal is required to prevent eutrophication (like algae bloom) of surface water bodies. The PHOSPAQ post-treatment process removes biologically degradable COD, phosphate (PO43-) and ammonium (NH4+) from wastewater. It takes place in an aerated reactor, which provides optimal conditions for biological conversion of COD and promotes struvite formation.

PHOSPAQ combines COD removal, ammonia removal, phosphate removal and phosphorus recovery in one reactor. This removal of phosphorus from wastewater deletes up to 95% of the phosphate in wastewater.

Sustainable phosphorus recovery with PHOSPAQ

As phosphorus is a scarce nutrient essential to all life, phosphorus recovery from wastewater is of importance. Recover of phosphorous from wastewater will contribute to a more circular society as it converts a waste product into a resource. PHOSPAQ allows facilities to harvest commercial phosphate from wastewater. By adding magnesium oxide, phosphate and ammonium will precipitate and form magnesium-ammonium-phosphate (so called struvite).The nutrient rich struvite is an excellent slow-release circular fertilizer.

Effluent polishing with ASTRASAND

To raise the effluent quality of (municipal) wastewater treatment plants, a treatment stage can be added to reduce concentrations of nitrogen, BOD, phosphate and TSS. ASTRASAND® is not only effective in removal phosphorus from wastewater, but also for the final removal of ammonia, nitrate, TSS and BOD. The ASTRASAND® filtration process removes phosphate to levels below 0.15 mg/l respectively.

With more than 40 years of experience and over 3,500 installations worldwide in sand filtration, Paques can provide every industrial or public facility with a tailor-made sand filter system that meets all requirements.
