Sludge transfer solution

09 July 2013

An EZstrip TR Muncher from NOV Mono has helped solve a maintenance problem for a German wastewater treatment plant, reducing the number of pipeline blockages occurring at the Käranlage Jagersfreude plant.

 

 The Mono Muncher is designed to provide efficient maceration of abrasive sludges in this type of application. Its layback cutter shafts are set at an angle to the incoming sludge flow, making it effective in capturing and macerating solids held in the flow. For the Käranlage Jagersfreude plant this helped to increase protection for pumps and other equipment further along the process line by minimising wear and reducing the needs for spares to be held.

 

If a rejection cycle is necessary, the Muncher can drop the object into the built-in trap which is set below the cutter stacks to prevent damage occurring. The waste trap has a large-diameter access port which allows for easy removal of debris, cleaning and flushing. The complete drive, gearbox and cutter assembly can be removed from the Muncher’s casing, without disturbing the pipework.
