Benefits of ECONITY Membrane ECONITY Hollow Fiber Membrane Technical Benefits Economical Benefits Porosity: High (above 77%) Pore Shape: Slit Type Permeability ↑, Screen Effect ↑ Manufacturing Process Stretching Method Manufacturing Cost ↓ Material HDPE(Hydrophilic Coating) Traditional Stability & Safety Chemical Resistance: Strong Life-time: Long Construction Cost ↓ Nominal Pore Size 0.4 μm (Micro Filtration) Complete Separation of Solids & Bacteria High Packing Density Footprint: Small Energy Consumption: Low OD/ID/Wall Thickness 0.65/0.41/0.12 mm Membrane Replacement Cost ↓ Operation Flux 0.3~0.5 m3/m2/d 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 for Air Distribution Uniformly
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 )

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 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 Advantages of e-MBR

24 A2O, SBR and Other Conventional Type
High Quality Effluent (Unit : mg/L, Nr/mL) Effluent Parameter A2O, SBR and Other Conventional Type +Tertiary Treatment +Disinfection e-MBR Typical Level (without chemical)  Achievable Level (with chemical) BOD5 5 ~ 10 < 2 SS < 1 T-N 5 ~ 15 < 15 < 10 T-P 0.5 ~ 1.5 < 1.5 < 0.5 Coliforms < 200 < 30 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 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%.
