JWC Environmental unveiled new wastewater technologies to help fight the disposable wipes crisis. The patent-pending innovations to its Muffin Monster® family of grinders and Monster Separation Systems® fine screens were highlighted at WEFTEC 2014 in New Orleans.
JWC identified that waste treatment plant operators were increasingly facing downtime, high maintenance costs and additional risk for workers due to disposable wipes being flushed into the sewers. Once in the sewers, the wipes are clogging pumps, fouling plant systems and causing overflows. In addition, a 2013 report done by the Association of the Nonwoven Fabrics Industry (INDA) shows that the wipes market is slated to increase 16% year over year. This growing issue will only compound problems for operators if attention is not given to finding solutions. JWC focused its research efforts on better ways to capture the wipes, cut them to a size that will not clog pumps and finally remove them from the waste stream.
JWC has introduced its new Delta-P side rails and perforated drums to its Muffin Monster® and Channel Monster® family of grinders. These two advancements ensure the capture of all items in the waste stream, including wipes, and drive debris into the cutter stack. These technologies prevent the bypass of full wipes or build-up on the grinders while maintaining the required high flow rate.
Improved cutting is achieved through new wipes-ready cutters, as well as tailoring the speed of cutter rotation with optimized cut control. These improvements achieve the desired 2-D cutting capabilities to control both the width and length of output, preventing materials from forming long strips and reweaving in the waste stream.
Finally, the new StapleGuard™ UHMW panels and brushless cleaning system are being introduced on the Finescreen Monster® to remove wipes at the headworks. The advancements in fine-screening technology mean high capture efficiency with little carryover, as well as more effective perforated panel cleaning without the use of a high maintenance brush system.
