10 10 ECONITY Membrane

11 11 Principle of Hollow Fiber Membrane

12 12 Surface of ECONITY Membrane Outer Inner

13 13 Technical BenefitsEconomical Benefits Manufacturing Process Stretching Method Porosity: High (above 77%) Pore Shape: Slit Type Permeability, Screen Effect Manufacturing Cost 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 m 3 /m 2 /d ECONITY Hollow Fiber Membrane Traditional Stability & Safety Chemical Resistance: Strong Life-time: Long Membrane Replacement Cost Complete Separation of Solids & Bacteria High Packing Density Footprint: Small Energy Consumption: Low Tolerance of Fouling: Strong Term of Chemical Cleaning : Long Construction Cost Maintenance Cost Benefits of ECONITY Membrane Note : Membrane Life time is usually around 8~10 years and may vary subject to influent & operation conditions.

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

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

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

17 17 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 Features of ECONITY Membrane System

18 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 19 e-MBR Process ( New Excellent Technology No.337 Certified by Ministry of Environment, Republic of KOREA )

21 21 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

22 22 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)

23 23 Advantages of e-MBR

24 24 High Quality Effluent Effluent Parameter A 2 O, SBR and Other Conventional Type +Tertiary Treatment +Disinfection e-MBR Typical Level (without chemical) Achievable Level (with chemical) BOD 5 5 ~ 10< 2 SS5 ~ 10< 1 T-N5 ~ 15< 15< 10 T-P0.5 ~ 1.5< 1.5< 0.5 Coliforms< 200< 30 (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.

42 42 e-MBR Energy Users 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%. 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. Attachment 1
