Case Study: Municipal WWTP (Webster, TX)

Model of Multi-Disk Screw Press – MDQ-354C

Start of operation – 2018 August


The customer had an interest in reducing sludge disposal costs in their municipal wastewater treatment plant by obtaining lower maintenance costs and lower energy consumption. The plant treats wastewater from nearby residential areas and numerous local restaurants and generates about 120 gallons of aerobically digested sludge from their digesters per minute.


On-site pilot tests were carried out, using mobile dewatering unit MDQ-201, to find the best dewatering technology. According to the test results Esmil offered sludge dewatering complex based on Multi-Disk Screw Press MDQ-354 C. The complex includes macerator, polymer feeder and service platform.
