Biological Phosphorus Elimination

Biological phosphorus elimination is getting more and more important in the recovery of phosphorus as a limited resource and for compliance with statutory limit values. With VIT®, the Bio-P process can be monitored with ease.

The Bio-P process

In contrast to chemical phosphate precipitation, the Bio-P process is an elegant, environmentally sustainable and cost-effective method for reduction of the phosphate concentration in the effluent. In addition, biological phosphate elimination generally allows for recovery of phosphorus, which is a limited resource.

Control with VIT®

The ratio of PAO to GAO is essential for the stability of the Bio-P process and has to be montitored constantly. This can be done with the help of VIT® gene probe technology. VIT® gene probes enable you to visualize both of these important organism groups and to examine the current relation of both groups.
