Dewatering Systems

Sludge & Solids Handling

The Right Dewatering System

It is important to select the correct DeWater® System for your application. Solids dewatering is accomplished at various stages of the solid’s life cycle. An industrial solid’s life cycle typically starts with the receiving of raw materials and it goes through a process to maximize solids recovery.  It does so through sedimentation of solid waste present in the water. These materials may be organic or inorganic, minute insoluble specs to large gross solids. They range from a highly liquified fluid to a near non-leachable cake.

Dewatering is  necessary for a number of reasons: It reduces disposal costs, improves self-life stability, minimizes odors, and can prevent a valuable resource from going to waste. The poor disposal of wastewater pollutes various water sources leading to scarcity of this precious commodity. The only solution here is to reuse or recycle wastewater through a viable treatment process. PEWE is proud provide our clients with innovative process and wastewater treatment solutions with the full array of DeWater® Systems covering the varying needs of the market today.

  • Reuse Wash Systems
  • Heavy Duty Stainless Steel
  • Ease of Maintenance

 DeWater® DBP Systems

The technologies included within each PEWE DeWater® DBP Belt Filter Press maximize solids recovery while minimizing chemistry usage during sludge dewatering. Each belt filter press has a wide solids loading range and can accommodate future plant process changes as well as higher throughput or cake dryness requirements. Selecting the appropriate belt press system is determined by evaluating the characteristics of the sludge solids that are encountered. These industrial dewatering systems are available in many different configurations. Options such as pre-dewatering table belts, bearings, adjustable sludge plows, bearing lubrication and a belt cleaning and reuse/recovery systems.

 DeWater® TRU Systems

The PEWE DeWater® TRU Truck Receiving Unit is a rugged septage dump unit. The system receives influent from septage, vacuum or porta-potty trucks through an easy connect influent flange located on the front end of the tank. The liquid stream will be directed through a bar trap which collects objects larger than several inches in width. The influent then flows into a screen basket where the solids (which exceed the screen perforation size)  will be retained and transported up the transport tube. The free water flows through the screen to a wet well before the liquid is allowed to pass out a flanged effluent fitting for further processing. The solids transported up the tube undergo further dewatering until reaching the compression zone. At the compression zone solids pack, are rinsed, and then shed to the discharge chute and removed for disposal.

DeWater® AC Systems

The core of PEWE’s screw technology behind the DeWater® AugerConveyor AC is its unique spiral design. Engineered after physical principals, our design creates prime conditions for conveying semi or solid material ranging from 10% to 65% total solids. These materials easily rise up the slick stainless steel and UHMW wear surface. The DeWater® AugerConveyer AC may be angled at a maximum of 25 degrees to assure complete solids discharge out the top mounted chute. These systems are sized generously to allow for 10, 20 and 30 cubic yard roll off dumpster to readily clear the discharge chute. Guard covers protect the auger.
