Cleveland Bay wastewater treatment facility

Print This Article

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.

This solution offered the flexibility of effluent from the plant being treated in a water reclamation facility, which includes reverse osmosis, to produce high quality reuse water suitable for industrial and irrigation applications.

As a direct result of the design team’s innovation, the Alliance successfully completed one of world’s first retrofits of existing clarifiers to house the BNR and membrane treatment process trains.

Because all wastewaters are different, it is necessary to work with a team that can combine comprehensive knowledge with practical experience in the fields of chemistry, biology, hydraulics, mechanical processes/equipment, instrumentation and control, materials handling and plant layout.

GHD can deliver on all the process components that make up a wastewater treatment plant. We have designed and project managed more than 300 wastewater treatment plants (including major municipal facilities processing 500Ml a day and industrial projects).
