How AirPrex™ Optimises the Sludge Treatment Process Like No Other System

Until now, the main methods of struvite removal have been:

    • Costly, recurring chemical treatment
    • Phosphorus removal after dewatering

Unlike these other systems, AirPrex™ is a complete sludge optimization and phosphorus recovery system that’s installed between anaerobic digestion and sludge dewatering step. The conditions for controlled struvite precipitation are set by air stripping in the AirPrex™ reactor with the addition of a magnesium chemical product. The combination of biological phosphate elimination and the AirPrex™system achieves unrivaled effectiveness in terms of wastewater dewatering efficiency and cost savings.
