The DOF System

1) Brief Introduction of the DOF Technology - The DOF system is a Combined Technology of the DAF system with Ozone. The DAF system has the excellent flotation performance of the suspended material and Ozone has the highest Oxidation Potential. So that the DOF system is the excellent flotation system with strong oxidation power. - Pressurized water (4~8kgf/?) containing ozone is released through a micro- bubble producing system at the flotation basin to removal turbidity, organics, color, phosphorus, and microbial agents. - Certified Environmental New Technology from the Korean Environmental Ministry, Authorization No. 143, and Verification No. 85. 2) Advantages of the DOF technology - Excellent removal performance of THMFP, algae, color, taste and odor in drinking waster treatment. - Excellent performance in removing COD, color, microbial agents, and phosphorus in wastewater treatment. - High removal rate of non-biodegradable organics in leachate produced from the landfill site, and livestock wastewater. - Broader Application than Filtration, Membrane, and UV disinfection technologies - By over 96% ozone utilization rate, ozone facility cost is reduced. - Off-gas of the DOF system may be utilized in removing odor produced in the system process 3) Application Area of the DOF System - Advanced Treatment of Drinking Water for removing THMFP, color, taste and odor. - Advanced Treatment and Disinfection of effluent of the wastewater treatment plant. - Water Reuse - Color and COD Removal in the Dye and Pigment Wastewater. - COD and color removal in livestock wastewater. - Advanced Treatment of a small scale wastewater treatment plant.
