High Water Recovery and Reduction of Chemical Oxygen Demand (COD) in Industrial Waste Water.
A major US consumer goods producer generates high COD wastewater from which they want to achieve high recovery and <2,000 mg/L COD in the treated water. Water from rinsing activities at the plant contains surfactants, making it difficult to increase recovery to the goal of 90%. The desired treatment process would treat 105,000 gallons per day, minimize retentate, and reduce downstream chemical costs required to mitigate elevated COD.
Optimizing Reuse of High Load Wastewater
An aquaculture company was seeking to treat high nutrient wastewater from their fish processing operations. They needed to meet a discharge limit as well as create a value added waste prod-uct from the concentrate. The critical parameters were to reduce the COD below 500 mg/L and to achieve a >5X concentration of phosphorus in the waste. This concentrate was evaluated by prospective customers in the fertilizer market.
Reduction of Total Biological Oxygen Demand (BOD) in Industrial Waste Water using a Single Stage Solution
A major US meat producer located in the Midwest generates high nutrient waste water from one of their production facilities. Water from rinsing activities contains soaps, oil/grease, and sugars making it difficult to remove soluble compounds that contribute to high BOD. The plant needed a wastewater treatment process that would treat 10,000 gallons per day to less than 300 mg/L BOD.
Optimizing Re-use of High Load Wastewater
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.
