Optimizing Re-use of High Load Wastewater
Pineland Farms Dairy
Pineland Farms was building a new cheese processing plant in Maine and needed to ensure that the cheese whey and wash water effluent being discharged met the municipality BOD discharge limit of 350 mg/L. They were interested in evaluating a small footprint treatment solution that could meet the discharge limit, and could also increase water re-use in the future.
To meet both the discharge limit as well as maximize water recovery, Cerahelix worked with technology partner, Howell Laboratories to combine our picofiltration technology with their electrocoagulation (EC) equipment. Together we installed a pilot unit composed of an EC equipped with aluminum electrodes and a cross flow filtration system containing our ceramic PicoHelix membranes.
The process synergy is that the ceramic PicoHelix membranes resist fouling from the EC effluent, while the recycled membrane retentate increases both the EC and overall process efficiency.
