AirPrex® Macro, besides struvite harvesting, includes further P release into the second mixing tank where further struvite growth and sedimentation occurs, enabling microcrystals recovery.
The same benefits as AirPrex® Micro and additionally:
- Increase of cake dryness by up to 4%
- Less polymer consumption (15-25%)
- Reduction of ortho-P by 95 % in the filtrate (internal recycling)
- Prevention of crystallization in the sludge- and centrate area
