Esmil Multi-Disc Screw Press MDQ

TYPE OF INDUSTRY Food and beverage industry


In this plant sludge from DAF-unit and MBBR reactor was stored on-site in tanks and its utilization was outsourced to an external company. Due to expensiveness of such service, it was decided to build a local dewatering facility to reduce sludge volume and its disposal cost.


Esmil company offered a sludge dewatering solution based on one multi-disc screw press dehydrator MDQ-353 C. Other auxiliary equipment including a polymer solution preparation unit and pumps as well as piping was supplied by our local partners, assembled by the customer and commissioned by Esmil representatives to meet the highest dewatering process efficiency.

End User’s Comment

Since the comissioning, the performance of the dewatering equipment has been stable, highly efficient and with no issues. High dewatering efficiency resulted in significant sludge volume reduction, so the construction of the local dewatering facility has paid off very quickly.
