The Problem

How AirPrex Optimizes the Sludge Treatment Process Like No Other System

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

  • Costly, recurring chemical treatments
  • 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 dewatering. The boundary conditions for struvite precipitation are set by air stripping in the AirPrex reactor and the addition of a magnesium chemical product. This combination of biological phosphate elimination and the AirPrex system achieves unrivaled effectiveness in terms of wastewater dewatering efficiency and cost savings.

Benefits

AirPrex Removes Struvite while Significantly Improving Efficiency

The AirPrex process has been designed to produce maximum return on investment and make a significant impact on your treatment plant’s cost of operations. The elimination of struvite through this unique process leads to a 90 to 95 percent phosphate reduction in the returned liquor (up to 15 percent related to the incoming P-load).
