GHD was commissioned to design a new Biological Nutrient
Removal (BNR) and membrane treatment system for the Cleveland Bay
Wastewater Treatment Facility, with a capacity to cater for an
estimated population of 126,000 people.
State-of-the-art biological processes were introduced, by
combining an oxidation ditch (to achieve a high level of nutrient
removal) with membrane solids separation, to achieve a very high
effluent quality. This approach retains the simplicity and
flexibility of the oxidation ditch while adding the exceptional
solids separation capability of the membranes.
