Reliable solids measurements for centrifuge control
Vaasa Water’s Pått wastewater treatment plant wanted their new centrifuge to operate fully automatically, which requires several continuous measurements. With a Valmet TS and Valmet DS the plant can control the polymer dosing and measure the dry content. The whole project paid for itself in about 1.5 years through the considerable savings in the reprocessing costs of the dried sludge.

Successful I/O migration at Borealis Porvoo
The Borealis Polymers Porvoo plant in Finland, a fully integrated petrochemical complex, has been controlled with automation from Valmet since 1993. As a result, several generations of automation have been periodically extended and upgraded until ultimately replaced as components reach end of life and new technological solutions are introduced. As part of a modernization project to the Olefin Cracker in 2017, Valmet undertook the major task of replacing over 3000 centralized input/output (CIO) cards in 31 I/O cabinets.
