Valmet to supply 22 microwave solids measurements to the Greater Paris Sanitation Authority in France

Valmet Oyj’s trade press release on March 22, 2022 at 11:00 a.m. EET

Valmet will supply 22 Valmet Total Solids Measurements to the Greater Paris Sanitation Authority’s (SIAAP) Seine Aval wastewater treatment plant in France. The measurements were purchased by the technology provider: the temporary joint-venture between OTV and STEREAU, OTV being the mandatary. The measurements will be installed in the plant’s new primary decantation to accurately measure the total solids of the sludge, produced by lamellar settlers.

The order was included in Valmet’s orders received of the fourth quarter 2021. The measurements will be delivered during the second quarter 2022.

The SIAAP plant is about to undergo a transformation. The existing static settlers are replaced by lamellar settlers, including a new pumping station and an additional pretreatment stage. The goal of the new unit is to increase process performance and to reduce nuisance for the neighborhood. The measurements will help the customer in daily process control to ensure the right sludge concentration for downstream process. In addition, they will bring energy savings and further environmental benefits.

"We were confident about the choice of Valmet’s sensor. We made a two-month trial last summer by installing a Valmet Total Solids Measurement on an existing customer process together with the Valmet team, which fully convinced our client. The results were better than expected, especially considering the short time we had to commission the sensor," says Jerome Caubit, Project Director, OTV.

"Valmet Total Solids Measurement utilizes the latest microwave technology and is already recognized as a reliable and accurate sensor in several wastewater applications. We see that the demands for this kind of measurement are constantly growing," says Christian Guerry, Sales Manager, Automation, Valmet.
