Finland-headed forest industry and energy technology major Valmet has announced that it will deliver total solids (TS) online measurements to Shanghai Shidongkou wastewater treatment plant (WWTP) in China. The measurement solutions will enable the plant to reduce laboratory sampling as well as gain polymer, energy, and other cost savings. Built in 2001, Shanghai Shidongkou is located north of Shanghai and has a capacity to treat 400 000 tonnes per day.

The order consists of five Valmet Total Solids Measurement (Valmet TS) units. One of the units will be installed before sludge dewatering machines for polymer dosage control and four units will be installed after them for dry cake measurement.

– Valmet’s measurement is a reliable online solution. Devices will be installed in Shanghai Shidongkou wastewater treatment plant’s feeding and outlet pipe of the dewatering machine. They will enable the wastewater treatment plant to save on polymer dosing and monitor dryness of the dry cake, said Gu Jianhua, Design Manager at Valmet’s local distributor Zexi Environmental Protection Co., in a statement.

The Valmet TS is based on microwave technology and, according to Valmet, is a reliable and accurate meter for all wastewater sludge treatment applications (0-40 percent total solids), providing savings in energy, polymer dosing, and transportation.

– Based on several successful references in China, we are confident that this innovative technology will offer reliability to the end customer in optimizing wastewater treatment plant operation, said Kevin Li, Channel Manager, Automation, Valmet.
