Mono muncher minimises ragging

To increase process efficiency at its Warrington North (Gatewarth) wastewater treatment works (WwTW) by preventing pump blockages and minimising down time, United Utilities has specified a TR Muncher from NOV Mono. The TR Muncher macerates heavy solids and rags to a small particle size.

To ensure the two Mono grinders could be incorporated into existing pipework at the base of the well,Mono engineers took the decision to move forwards two existing Flygt pumps and fabricate new discharge pipework for the installation. They also replaced old gate valves with new, slimmer, knife valves in order to isolate the sludge flow for pump maintenance.

The TR Muncher, which has a capacity range of 0- 500m3/h raw sewage, features the latest generation of twin shaft grinders and is designed specifically for the efficient treatment of abrasive sludges.
