Customer case:

Optimized control in different positions

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.

Total Solids Measurement

Valmet Total Solids Measurement (Valmet TS) is a reliable and accurate microwave real time measurement used to control and optimize the solids treatment process, giving operators information on the total solids 24/7.

High Solids Measurement

Continuous accurate measurement of over 30% total solids for a wide range of industrial applications utilizes microwave technology to make a continuous and accurate solids measurement.
