Problem: The Barberton (Ohio) Wastewater Treatment Plant had enhanced its biosolids management system with an Esmil MDQ-404CL multidisk screw press, improving dewatering and reducing operating costs. However, during a renovation of the dewatering building, the new press could not be used, and no backup solution was available.
Solution: Esmil deployed its Module D containerized dewatering unit. The plug-and-play system includes a high-performance MDQ-503CS multidisk screw press, polymer feeder, macerator, control system and screw conveyor, all in a climate-controlled 40-foot container. With just three connection points — solids, power and water — the system was installed quickly. Esmil technicians configured the system and trained the operators.
Result: The unit operated at 60 to 70 gpm, processing sludge at 3.5% solids and delivering a 26% solids cake. Its reliability, energy efficiency, low maintenance and zero downtime made it an effective temporary solution. 646-286-5512; www.esmil.us
