Cake solids measurement elevates dewatering control

Mar 19, 2024

JEA’s Buckman Wastewater Treatment Plant, in Jacksonville, Florida, processes 28 million gallons of water every day. This is the largest regional sewer plant with advanced nutrient removal. JEA chose Valmet Dry Solids Measurement (Valmet DS), installed on the dewatering centrifuge, for accurate cake measurement. It’s been implemented for the plant wide mass balance control scheme. With Valmet’s solution the plant can now observe real-time cake solids output, allowing them for better control for their dewatering process.
