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 weeksRecovery cleaning : 1~2 times / yearThe Materials are Highly Resistant to Chemicals & Other Impacts
18 Quality Certification of Membrane by Public Procurement Service, Republic of KOREANote : The original company name was ‘KMS.” The company had its namechanged 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 characteristicsSmaller Site (50% Reduction) & Lower Civil Work Cost- Does not need sedimentation, clarifier, disinfection, etc.Waste Disposal Cost Saving- Due to substantial sludge reductionEffluent 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 removalthrough DO control in Oxic 1Energy 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 realizesadditional aeration saving (optional)

42 Attachment 1 e-MBR Energy Users Note : This is the result from pilot scale (60㎥/day) testand specific inlet loading condition, so it can be differentaccording 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%.
