Sludge transfer problem solved in Germany

NOV Mono has helped solve an ongoing maintenance problem for a major German wastewater treatment plant with the installation of an EZstrip™ TR Muncher. The Mono Muncher® has dramatically reduced the number of pipeline blockages occurring at the Käranlage Jagersfreude plant – the largest facility of its kind in the Saarbrücken area.

The customer's previous macerator had been experiencing increasingly frequent blockages – often one each day - due to the 8-12% dried solids and fibre content of the raw sludge it was handling. The process of repeated de-ragging was both time consuming and expensive, so an alternative solution was sought.

The Muncher was designed specifically to provide efficient maceration of abrasive sludges in this type of application. The Muncher's layback cutter shafts are set at an angle to the incoming sludge flow, making it extremely 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 so reducing the needs for spares to be held. www.mono-pumps.com
