Company /United utilities / Drainage Consultant Envirocare Northwest had an enquiry from a local Fruit & Veg company to provide a treatment plant to reduce the solids generated from a potato rumbler which was producing an effluent which exceeded the companies trade effluent suspended solids discharge consent limit
Following an on-site meeting UU requested that the discharge should be reduced in solids content by installing a balance tank system prior to discharge to the public sewer, Four silt traps were installed with a settlement volume capacity of 6 m3 equivalent to three days production which would be desludged and the starch/potato water collected by a local pig farmer to be sterilised /blended for animal feed
1. Excavation, transfer off site of spoil and positioning of silt tanks
