Customer case:

Optimized control in different positions

May 29, 2020

Shanghai Taihe underground wastewater treatment plant processes 400.000 tons of sludge per day. The plant stabilizes sludge pumping process and optimizes polymer dosing with Valmet Total Solids Measurements (Valmet TS) and Valmet High Solids Measurements (Valmet HS).

We have seen the good performance of Valmet measurement in Bailonggang and Shidongkou Plant few years ago, this time we believe that the stable results can give us more space to improve the plant efficiency.
