Unused useful matter sewage treatment plant

Sewagewater contains many nutrients that are not or not optimally used.

Waste water consists phosphate, which is a raw material for several applications. For example, phosphate can be used as a fertilizer for agriculture. Besides that, phosphate can accumulate at inconvenient spots in the waste water treatment plant.

The Airprex technology is a process to recover phosphate in the form of struvite. The struvite installation is capable to produce 2.500 kilogram per day maximum. This causes a cost reduction of €400.000 per year.

• The recovery of phosphate is a positive influence to the environment because less phosphate ore has to be produced. Phosphate is a finite raw material and essential for food production.
• By recovering struvite it can not accumulate at inconvenient spots in the waste water treatment plant which causes a reduction in operational costs.
