The SWM-XE Screenings Washer Monster from JWC Environmental includes a Smart Controller, low-profile stainless steel tank, and triple zone washing. The system can be directly fed from the screening device or through a conveyor or a sluice, and is designed to grind, wash, compact and dewater debris. It is available as part of the Monster Separation System fine screens or for cleaning solids from an existing screen installation.

The Smart Controller automatically monitors power demand on the compaction screw and selects the optimum run cycle via three programmable stages to provide the proper level of washing for a clean, dry discharge.

“It’s like having an engineer on site,” says Rob Sabol, director of research and development. “One thing we have learned is that each facility has many variables that require adjustments to run times and wash water duration. The controller takes the knowledge we’ve acquired and allows each site to draw upon and use it.”

An initial wash zone in the hopper sprays incoming solids, providing better processing through the grinder. A second zone, just beneath the grinder and above the auger screw, provides thorough washing. Shredding of the solids with the grinder exposes more surface area, making washing more effective.

“It makes it much easier for the washing and compacting of the solids,” Sabol says. It also results in a safer, more compacted discharge. “Syringes that may contain liquids that can be dangerous to plant personnel are now destroyed or broken, and the shredded material compacts easier than whole solids,” Sabol says.

The third wash zone under the screen ensures that the liquid discharge from the tank remains clear and clean, maintaining the capacity of the system. Solids content can be up to 50 percent dry. “At most sites where we put the systems in, you’re looking at 85 percent or higher volume reduction,” Sabol says. “This means fewer trips to the landfill.”

The system can process 150 cubic feet per hour and has a wash water capacity of 330 gpm. Options include discharge bagger, roller base, custom hoppers and custom discharge lengths. 800/331-2277; www.jwce.com.
