PHOSPAQ

PHOSPAQ technology is a cost-effective and sustainable way to meet discharge requirements ánd recovery of resources from wastewater. LCA studies show that recovery from phosphate by formation of struvite has significant environmental benefits.

Advantages of PHOSPAQ™

PHOSPAQ combines the removal of COD with the removal and recovery of nutrients like ammonium and phosphate. PHOSPAQ removes up to 95% of the phosphate in wastewater. PHOSPAQ as been applied or treatment of municipal sidestream reject waters as well as in industrial wastewaters increased.

Feasability of PHOSPAQ

PHOSPAQ is feasible from approximately:

  • Load: > 100 kg P/d.
  • > 50 mg/l PO4-P
  • > 200 mg/l NH4-N

PHOSPAQ for removal and recovery phosphate

The PHOSPAQ process removes biologically degradable COD, phosphate (PO43-) and ammonium (NH4+) from wastewater. PHOSPAQ is often implemented to increase the phosphorous removal to meet stringent discharge limits. It also prevents downstream struvite scaling of piping and equipment saving maintenance cost.

As phosphate is a finite resource essentially for all life, phosphorus recovery from wastewater has become paramount. PHOSPAQ allows facilities to harvest phosphate in the form of magnesium ammonium phosphate (struvite) which can be turned into a slow release fertilizer or used as feedstock for other products like fire retardants. PHOSPAQ is a cost-effective and environmentally friendly technology for phosphorus recovery.

How PHOSPAQ works

The PHOSPAQ process takes place in an aerated reactor. Aeration provides optimal mixing of the struvite particles, simultaneously supplying oxygen for the biological conversion of COD. Stripping of carbon dioxide increases the pH and promoting struvite precipitation.

Magnesium oxide is added to remove phosphate that is recovered by precipitation as magnesium-ammonium-phosphate (struvite). The PHOSPAQ reactor is equipped with separators that retain the struvite and discharges the purified effluent.

The struvite is harvested from the bottom of the reactor and can, depending on the outlet requirements, be further processed, purified and dewatered.
