Zero Effluent Discharge System


  • Amount of condensate returned to the boiler is increased from 40% to 80% of total steam consumption, thereby reducing energy costs for preheating the make-up water
  • Reduced chemical treatment costs for boiler make-up water
  • Essentially eliminates wastewater disposal fees
  • Simplifies plant permit application process due to the elimination of a major effluent source
  • Supplies 75–100% of the sparge steam needed for typical Desolventizer-Toaster operation
  • Superheated sparge steam supplied by the ZED System can potentially improve the meal drying, reduce solvent loss and increase the digestible protein in the product
  • Additional wastewater sources can be incorporated into the ZED System for recycling
