"We've dissolved the partnership with our Germany-based partner to build on the strength of our U.S.-based initiatives and learnings. Changing our nutrient recovery technology's name to MagPrex (previously AirPrex) signifies our commitment to continued innovation and ensures the best efficacy and the best value for all of our North American customers." – Gerhard Forstner, president of CNP
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:
