Enhancing productivity in biogas application

A biogas facility in Catalonia, Spain, invested in a 30K in-line Muffin Monster™ to reduce downtime and maintenance costs.

Case studies of Monster Muffin

The challenge

  • Imported loads included many inorganic problem solids that caused big clogging problems for the in-line chopper pump    
  • The pump was replaced with a progressive cavity pump, but the problems remained
  • First stator had to be replaced after just six months of operation

The project

  • An in-line 30K Muffin Monster was installed
In a system where the feedstock can vary, the use of a grinder can help make a more homogenous waste stream providing operational and maintenance savings. Andy Bruckshaw, Director of Sales at JWC Europe
