The company is an award-winning dairy producer and has a dedicated and strong approach to being environmentally responsible. This, of course, includes managing their wastewater. Their Sustainability Report states:

Waste reduction continues to be challenged. Each site discharges wastewater to either an on-site treatment facility or direct to sewer. Wastewater is monitored and targeted to reduce Kg/COD per tonne of product.”

Alfa Laval UK partnered with Cap Technology in 2015 to deliver the best possible solution to the Chester dairy. Cap Technology with its strong experience in wastewater treatment chose Alfa Laval’s MBR membrane solution for its compact technology and the high quality of the treated effluent. The simplicity of the gravity-operated membranes combined with the very low amount of cleaning chemicals required, made the Alfa Laval MBR membranes a very attractive solution.

 

The operators control both the dairy processing plant and the MBR remotely. Since the plant was commissioned in 2015, the customer has mapped and clearly understood how the different process streams impact on the performance of the MBR. In the last five years, by optimizing the release and composition of the process streams to the MBR, they have reduced the amount of cleaning required by more than half compared to the initial operation, while increasing their production.

The MBR installation has given us confidence in the discharged waters to river, improving our discharge contaminants to low levels previously unseen. The simple operation of the plant now allows our focus to shift towards stopping waste going to drain as we have the confidence of the system. Operating costs have vastly reduced since the plant was installed and the MBR filters have been a pleasure to operate, with little involvement from any operators.”
