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.
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.
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.
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.
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.
