Mono Muncher sends biogas yields up in Spain

The installation of a Fluid Motion Solutions’ (part of NOV Inc) Mono Muncher at a biogas plant in Spain has helped increase gas yields by eight percent.

Designed for the homogenization of sludge in digestion, feeding and recirculation, the inline Mono Muncher’s tearing, shearing and crushing action has removed a bottleneck in the system that was causing blockages, downtime and significantly extra maintenance.

Supplied with a custom-designed control system, the 180 m3/hour flowrate shredder has a proven track record of protecting pumps from blocking by fine-grinding AD feedstocks such as municipal sludge and food waste. In the event of an object initially being too strong, the Mono Muncher’s overload protection technology reverses the cutters (to clear the cutter stack), with any solids falling into the trash trap.

The Mono Muncher can also be utilised in a wide variety of industrial applications where solids such as plastics, clothing and bones need to be reduced in size. These include mud-contaminated drill cuttings, aircraft sewage, abattoir waste, and wastewater from prisons.
