Biological Phosphorus Removal for Wastewater

MagPrex Optimizes the Sludge Treatment Process Like No Other System

The Affordable Option Giving All Plant Sizes the Ability to Control Struvite and Recover Phosphorus

MagPrex turns struvite into an opportunity for resource recovery. In wastewater reclamation plants with Biological Phosphorus Removal (BPR), phosphorus accumulates in sludge and releases soluble phosphorus (PO4-P) in an anaerobic condition. Elevated soluble phosphorus levels in sludge causes operational challenges.

Form struvite by stripping out CO2, elevates the pH and adds MgCl2 to augment Mg2+

Install between the anaerobic digester and the dewatering equipment

Convert the orthophosphate into struvite crystals with two recovery options:

• Harvesting: struvite crystals are removed from the digested sludge and used as a beneficial fertilizer
• Sequestration: leave the struvite crystals in the sludge
