Dairy processor WWTP view Berghof Membranes

A dairy processor based in Richland County, Wisconsin, challenged Berghof Membranes:

• to find an efficient process to generate electricity and heat from whey and other high strength liquid waste, left over from the manufacturing of cheese and yogurt from cow’s milk, and
• to further treat anaerobic industrial wastewater discharge with high levels of solids before discharging to a nearby river.

The stream being treated is the segregated and diverted high-strength wastewater from multiple milk processing factories. The volume and strength of this combined wastewater vary considerably from day to day. Total flow to the industrial wastewater treatment facility is expected to average up to 2,160 m³/day.

Berghof Membranes, with its experience in treating industrial effluent using PVDF tubular membranes, developed a compact AnMBR system for the Wisconsin-based dairy processor. The Berghof system ensures complete retention of the biomass within the anaerobic digester and brings a significant improvement in the digestion process, making it more robust, reducing the footprint, increasing biogas production and delivering superior effluent quality.
