The patent pending Channel Monster FLEX consists of a FLEX Grinder and a Solids Diverter with perforated screen connected by a FLEX Frame. The Channel Monster FLEX continues the Channel Monster legacy of high flow capacity while capturing and shredding rags, rocks, wood, and other solids into small pieces to pass harmlessly through pumps, pipes, and process equipment.

JWC Environmental’s Monster Wash Press (MWP) cleans and compacts the discharge from headworks screens, separating water and organics from the solids.  It features a Muffin Monster® grinder to pre-condition screenings before entering the Monster Wash Press.  The grinder breaks open rags, plastics and trash to promote washing and removal of soft organics.  The patent-pending paddle rotor in the active wash zone agitates the material to enhance water penetration throughout the debris for even better removal of the organics from the solids.  Organics are washed back into the wastewater treatment process and the solids are compacted into a dry, less odorous solid plug.  The Monster Wash Press is designed for easy maintenance.  The rotor and field replaceable screen can be removed via the top of the unit, minimizing the clearance space needed around the unit during maintenance.  A grinderless version of the Monster Wash Press is also available.

All-In-One Headworks Solution – Grind, Screen And Compact
The Auger Monster® is a robust headworks solution which combines three of JWC’s finest technologies – a grinder, a fine screen and a compactor. It removes trash and unwanted solids so the treatment plant runs more efficiently. The Auger Monster is proven to result in cleaner, more compact discharge and lowered disposal costs, as less water and fecal material are sent to the landfill.

From waste to wealth
More and more wastewater treatment plants are trying to find ways to reuse their valuable sludge through anaerobic digestion as well as lower their overall carbon footprint. With our recent acquisition of IPEC we now have world class solutions to meet your sludge thickening needs.

Are you wipes ready?
Wipes and rags are clogging pumps and damaging wastewater treatment systems. NEW Wipes Ready technologies from JWC will keep your systems running efficiently.

The 10K Series Muffin Monster is a compact grinder, tough on solids in sludge and sewage applications. It fits into areas with limited space requirements while still providing the necessary power for downstream protection. This simplified design makes it a best cost solution to your sludge and sewage pumping problems.

JWC Environmental is proud to introduce the new 7 SHRED grinder, built to fulfill the demands of product reduction for industrial applications such as in petroleum, agriculture, food processing, municipal solid waste and more.

The Auger Monster model AGV safely and easily screens, cleans and conveys rags and debris straight up and out of the sewer system. This gives collection system managers an affordable new way to remove rags before they clog sewage pumps, eliminating the time and expense wasted on de-ragging pumps.

The Finescreen Monster is part of the Monster Separation Systems® line of screens.  The Monster Separation System is a complete, high-performance system of screens and screening processing equipment that provides high capture rate of wastewater solids and more efficient washing and compacting, resulting in a discharge that is remarkably clean and ready for disposal. The more unwanted solids removed at the headworks of your treatment plant, the better the whole facility will run.

In today's modern wastewater treatment plants, meeting high standards in effluent quality, cost efficiency and odor control is a must. To meet these higher standards, JWC introduces the Bandscreen Monster, a member of the Monster Separation System line of high performance screens.

  • Wastewater Is Changing: Are You Protected?

    Today’s wastewater stream is dramatically different than its content just a decade ago. Yet, many municipal wastewater treatment plants are functioning under older designs and are not optimized for the new reality. There are solutions to attack the problem without the significant expense of a major system or plant overhaul.

  • The Importance Of Grinder Design In Pump Protection

    By breaking down solids into a manageable size, grinders allow pumps to work efficiently while avoiding downtime for cleaning and repair. However, not all grinders are the same. Here is a list of design features that are important to consider when making a grinder investment.

  • Get It Out: Effective Removal Of Inorganics

    Modern wastewater treatment processes are not designed to operate with inorganic solids in the waste stream. While grinders are typically a cost-effective method for protecting the pumps at pump stations, there are other critical junctures within a treatment plant where operators have an opportunity to protect valuable assets with screening technology.

  • A Simple, Effective Strategy For Preventing Clogs

    Municipal wastewater treatment plant operators face significant challenges from a surge in clogs. Wipes that have been marketed as flushable, but don’t necessarily break down like toilet paper, are increasingly ending up in the waste stream. And with the heightened sense of cleanliness related to COVID-19, consumers are using more wipes than ever, as well as personal protective equipment which is not meant to be tossed in toilets. The proper mechanical solutions can help mitigate the problem and make operators’ lives easier.

  • Combining Biosolids Waste Streams? Not So Fast…

    The idea of combining two systems into one sounds like a common-sense solution to simplifying operations.  Wastewater treatment plant operators have been experimenting with this concept by combining waste activated sludge with primary and septage waste streams with the goal of lowering system complexity.  The reality of these efforts is proving, in many cases, to be problematic.

  • Sludge Thickeners: The Good, The Bad, And The Smelly

    Management of wastewater sludge is a core responsibility of treatment plant operators. With this responsibility comes common challenges that must be overcome.  These include controlling odors so as to have a minimal impact on the surrounding community and minimizing hauling costs for its disposal.  Getting a handle on both of these responsibilities and more can be much easier with the proper sludge-thickening equipment.
