Reliable sludge measurement after dryer machine

Jun 19, 2023

Shanghai Zhuyan Sludge Incineration Plant, is one of the biggest incineration plants in China. They have invested in Valmet High Solids Measurement (Valmet HS) to monitor the high solid level before sludge incineration. Valmet HS uses advanced microwave measurement to continuously measure total solids over 30% and optimize the drying process so that the moisture level is just right, helping the plant stabilize their process.
