1. Abrasion- And Corrosion-Resistant Metal Cutters For Harsh Sewage Grinder Environments 9/8/2021

   Wastewater is tough on grinder cutters. Damaging abrasion wear and metal corrosion are caused by daily gritty material and acidic conditions in sewage. The combination of an abrasive and corrosive environment accelerates the loss of cutter material, resulting in the loss of cutter thickness and tooth edges.

2. What Is Monster Stack? 9/7/2021

   A JWC Monster Stack is a customized cutter stack that matches the right cutters to the expected challenges in the operational environment. As JWC uses individual cutters for its grinders, it is possible to mix different cutter types in the stack, and those changes can happen anywhere along the stack.

3. How Cutter Choice And Placement Impact Wastewater Grinder Performance 8/18/2021

   Not all tools have the flexibility to be configured to optimize performance. It pays to evaluate the wastewater flow approaching the grinder, as well as the cutter configuration.

4. Prefabricated Space-Saving Solutions To Sewage System Pump Clogging 8/4/2021

   Adapting to changes in sewage system demands over time is never easy due to the cost and complexities of modifying buried infrastructure.

5. Reducing Emergency Sewer Repairs 5/6/2021

   Wastewater treatment plant operators have dealt with clogging problems at their plants and pump stations for decades, but the meteoric rise in the use of disposable wipes and other non-dispersible products has accelerated the problem to epidemic proportions.

6. Wastewater Is Changing: Are You Protected? 6/22/2020

   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.

7. The Importance Of Grinder Design In Pump Protection 6/21/2020

   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.

8. Get It Out: Effective Removal Of Inorganics 6/20/2020

   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.

9. A Simple, Effective Strategy For Preventing Clogs 6/19/2020

   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.

10. Combining Biosolids Waste Streams? Not So Fast… 7/12/2019

    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.
