Esmil | Blog | News | Multi-Disc Screw Press Dehydrator commissioned in Canada

This year at the end of November an MDQ-102 C Multi-disc Screw Press Dehydrator was commissioned on the Avalon Peninsula in Newfoundland and Labrador, Canada (the most eastern part of Northern America). This is a first sludge dewatering co-project completed with our Canadian partners MABAREX. Since that time, the Multi-disk screw press dehydrator is operated as a main dewatering unit in a container wastewater treatment plant produced and commissioned by MABAREX. The WWTP is designed for processing of household sewage wastewater from a base camp of offshore drilling platform.

The nominal capacity of WWTP is 200 m3/day, and the screw dehydrator dewater 10-20 m3/day of excess activated sludge from MBR reactor with initial DS concentration of 0.5-1%DS. Cake dry solids concentration after the screw dehydrator is 15-17% that is enough for land disposal according to project requirements. A very clean filtrate (20-100 ppm of TSS) received after the dewatering process allows to reach a high capture rate – more than 97.5%.
