“Biffa were able to overcome a design challenge by utilising the custom built PPS range from Crest Pumps Group.”
Biffa PLC is one of the UK’s largest waste management firms, providing collections, landfill, recycling and specialist waste services.
Biffa were building a new anaerobic digestion plant in Cannock, Staffordshire. The site would accommodate over 120,000 tonnes of food waste per annum producing over 5 megawatts of electricity, enough to satisfy the demand of over 10,000 homes in the area.
Biffa enquired to Crest Pumps Group because of our ability to customise all process pumps at our UK manufacturing plant. Crest organised a site visit to the anaerobic digestion plant and worked closely with Biffa design engineers to fully understand their process difficulties.
As a result, Crest Pumps Group supplied two PPS 200 pumps with an extended column length of 4.5 meters to pump a chemical mix from a deep sump used to erode food waste into biogases. Due to the nature of the chemical mix, the PPS was built in polypropylene material to ensure long lasting corrosion resistance.
Biffa overcame design challenges by utilising the Crest pumps range of vertical pumps that are built to stand the test of time even when pumping harsh and acidic chemicals. Over the 5 years the pump has been installed, the PPS has needed little maintenance and continues to perform optimally.
