  13. Manufacturing Process Stretching Method Material HDPE(Hydrophilic Coating) Nominal Pore Size 0.4 μm (Micro Filtration) OD/ID/Wall Thickness 0.65/0.41/0.12 mm Operation Flux 0.3~0.5 m3/m2/d Benefits of ECONITY Membrane ECONITY Hollow Fiber Membrane Technical Benefits Economical Benefits Porosity: High (above 77%) Pore Shape: Slit Type Permeability ↑, Screen Effect ↑ Manufacturing Cost ↓ Traditional Stability & Safety Chemical Resistance: Strong Life-time: Long Construction Cost ↓ Complete Separation of Solids & Bacteria High Packing Density Footprint: Small Energy Consumption: Low Membrane Replacement Cost ↓ Tolerance of Fouling: Strong Term of Chemical Cleaning: Long Maintenance Cost ↓ Note : Membrane Life time is usually around 8~10 years and may vary subject to influent & operation conditions.

  14. ECONITY Membrane Manufacturing Plant Location : Yongin, Republic of Korea

  15. ECONITY Cartridge Module Permeate Handle ECONITY Hollow Fiber Membrane 320W×396H×490L, Weight 7kg

  16. ECONITY Frame Permeate Air “M” Type for Air Distribution Uniformly Sludge Discharge Aeration KMS-6007CF (1,326W×3,233H×2,948L, Q=600m3/day)

  17. Features of ECONITY Membrane System Energy Saving - Due to high packing density, improved air supply pipe & dual aeration(fine/coarse bubble) Easy to Clean & Maintain - Cartridge module is simple to insert/attach to/remove from frame -Light enough for one person to handle (cartridge module 7kg) - Cleaning in place (CIP) Maintenance cleaning : 1 time / 2 weeks Recovery cleaning : 1~2 times / year The Materials are Highly Resistant to Chemicals & Other Impacts

  18. Quality Certification of Membrane by Public Procurement Service, Republic of KOREA Note : The original company name was ‘KMS.” The company had its name changed to “Econity” in 2009

  19. e-MBR Process ( New Excellent Technology No.337 Certified by Ministry of Environment, Republic of KOREA )

  20. Features of MBR Process vs Conventional Type • High Quality & Stable Effluent • - Use of submerged hollow fiber membrane • - Not affected by sludge settling characteristics • Smaller Site (50% Reduction) & Lower Civil Work Cost • - Does not need sedimentation, clarifier, disinfection, etc. • Waste Disposal Cost Saving • - Due to substantial sludge reduction • Effluent Reuse • - Perfect removal of SS & coliforms

  21. Advantages of e-MBR vs other MBR Improved Nitrogen & Phosphorous Removal Efficiency - Pre & post denitrification with external carbon (optional) - Minimization of inhibition for nitrogen & phosphorous removal through DO control in Oxic 1 Energy Saving - DO recycle from oxic 2 to oxic 1 - Substantial energy saving during bio treatment in oxic 1 - Dual aeration(fine/coarse bubble) in membrane reactor realizes additional aeration saving (optional)

  22. Advantages of e-MBR

  23. High Quality Effluent (Unit : mg/L, Nr/mL) Note : Typical levels of N & P depend on influent characteristics such as C/N, C/P. Lower levels of N & P can be achieved by using additional chemicals.

  24. Required Installation Area Conventional Process (A2O+Tertiary) e-MBR Process Reducing around 1/2

  41. Attachment 1 e-MBR Energy Users Note : This is the result from pilot scale (60㎥/day) test and specific inlet loading condition, so it can be different according to plant scale and condition. In conventional MBR processes, aeration (bio aeration + membrane aeration) takes up over 70% of total energy used. E-MBR yields substantial energy saving, thanks to its efficient aeration process, from 70% to 50%.
