The Monster Wash Press from JWC Environmental cleans and compacts the discharge from screens, separating water and organics from the solids. Its Muffin Monster grinder preconditions screenings before entering the press. The grinder breaks open rags, plastics and trash to promote washing and removal of soft organics. The rotor paddle in the wash zone agitates the material to enhance water penetration throughout the debris for better removal of organics from the solids. Organics are washed back into the wastewater treatment process, while the solids are compacted into a dry, less-odorous solid plug. The compact design allows it to fit into tight installations and makes it ideal for upgrading existing systems. It is also available without a Muffin Monster, but it allows for a grinder addition in the future. 800-331-2277; www.jwce.com
