Feasibility Study for Management of Waste Activated Sludge, Manitoba, Canada

Secondary Clarifiers
A food processor was experiencing low hydraulic residence times at one of their anaerobic digesters during the discharge of waste activated sludge. a feasibility study identified that the most cost-effective option was to thicken and anaerobically treat thickened waste activated sludge (TWAS) in a new digester designed specifically for that purpose.

Advanced Oxidation using Ultraviolet Light and Hydrogen Peroxide

Advanced oxidation systems using hydrogen peroxide (peroxide) and ultraviolet (UV) light are designed to inject hydrogen peroxide in controlled ratios to the water, then mixing the peroxide, and exposing the water and peroxide solution to UV radiation to form hydroxyl radicals (•OH). Peroxide and hydroxyl radicals are strong oxidizing agents capable of oxidizing 1,4-dioxane and several volatile organic compounds (VOCs). The advanced oxidation process is suitable for groundwater remediation with pump-and-treat, water treatment, and industrial wastewater treatment. Treatment with UV/Peroxide may offer technical advantages over ozone based treatment systems.
