A global ice-cream manufacturer completed a four year, £25M investment programme at its Leeming Bar factory in North Yorkshire which included an on-site effluent treatment system designed, built and commissioned by Axium Process.  The system was engineered to enable the capacity of the effluent treatment plant to be increased with minimal disruption from 600,000 litres to 1.5 million litres per day.

This 2.5 fold expansion scope of supply also incorporated fully automated additional processes which were designed, installed and commissioned by Axium to further enhance the quality and condition of the raw effluent entering the membrane system.  A  removable sump debris catcher, aeration and mixing of large effluent holding tanks, triplex liquid solid separator prefiltration, vertical shell  and tube pasteurizers system (powered using excess heat from an onsite CHP plant), temperature controlled air cooling system and a pH adjustment tank were all new additions to the plant and were located on the same size foot print as the old plant.

The superior quality conditioned raw effluent passes through  4 x UF skids, with the UF permeate passed through a pair of double stage, double pass RO’s to recycle 90% of the effluent received to clean water for reuse back in the factory.  The 10% concentrated waste from the UF/RO batch process is retained and transported to an anaerobic digester where it is used to produce bio-methane.
