Avoid unnecessary process upsets. Increase the process stability. Improve the overall performance.

In many cases process upsets in activated sludge process may compose 5-20 % of COD and 20-60 % of phosphorous annual load to waterways. With PAULA-WWTP® injurious process upsets can be observed  and corrective acrions implemented before effluent quality is compromised.



Test PAULA-WWTP® at your mill.

The easiest way to discover benefits of PAULA-WWTP® is to organize a test period at your mill. Test period begins with mill database analysis for identifying the process data needed for predictive analytics.
