Energy savings and lower polymer costs in sludge treatment are among the benefits gained with Valmet Total Solids Measurement (Valmet TS) at Kajaanin Vesi in Finland. Kajaanin Vesi is a municipal water utility owned by the town on Kajaani in the Kainuu region of Finland. The plant treats about 4 million cubic meters of wastewater annually. In 2012–2013, the plant modernized its sludge treatment facility and had four Valmet TS units installed in the process. This reliable total solids measurement solution, based on microwave technology, is suitable for all wastewater sludge treatment applications in the range of 0–40% total solids.

Energy savings and lower polymer costs in sludge treatment.
Better control of the process and excessive pumping avoided when the total solids content is too low after primary clarifiers. Valmet TS informs the sludge solids amount and indicates how long to pump. Lower need for pumping consequently results in lower energy consumption.
