  • Milk Processing Wastewater Treatment

    A milk processing facility was using a 800 hp evaporator to dispose of their 0.75% solids concentrated milk waste stream. The staff was interested in evaluating the effect of using the Floccin products to capture the majority of the BOD and send this higher % solids/BOD sludge to the evaporator. The idea was to reduce the electric hp by reducing the volume of water going to the evaporator. Their ...
