  1. UF solutions for Urban InfrastructureTechnology & Applications

  2. Contents • Introduction • Ultrafiltration Technology • Potable water treatment • Sewage recycling systems • MBR Technology • Conclusion

  3. Ultrafiltration Applications WWTP UF RO Potable water production Surface water Ground water Seawater Effluent reuse

  4. Urban sector applications Ultrafiltration adds value for : • Potable water • Process water • Waste Water (re-use) • Seawater pre-treatment

  5. Filtration technologies Media Filtration 10 – 100 micron Micro Filtration 0.1 – 10 micron Ultra Filtration 0.01 – 0.1 micron Reverse Osmosis < 1 nm colour hardness Pesticides salts Suspended Solids bacteria colloids Viruses Large organics Settleable Solids 10 times smaller 10 times smaller Suspended Solids microbiology hardness pesticides salts water colloids viruses Large organics hardness pesticides salts water colour hardness pesticides salts water water

  6. Nominal pore size 20 nm Ultrafiltration membrane ~14.600 fibers 0.8 mm PES 8” module 0.8 mm (55 m2) 6 corrugated plates: optimal hydrodynamics

  7. Ultrafiltration membrane 8” X-Flow UF insert (40 m2) 0,8 mm fiber diametermax. pore size: 25 nm Corrugated plates:optimal hydrodynamics Bypass tubes:minimal pressure loss in housing

  8. Ultrafiltration membrane types • Hollow Fibre • Capillary • Tubular

  9. Potable water requirements Water Free from : • Silt • Colour • Odur • Taste • Hardness • Microbial contamination • Heavy metals Potable water should have salts and minerals to desired levels

  10. How effective is UF ? UFC Xiga & Aquaflex

  11. Complete removal of suspended solids TSS < 0.1 mg/lTurbidity < 0.1 NTU Removal of micro-organisms >Log 6 removal of bacteria>Log 4 removal of viruses Superb pre-treatment for SWRO SDI15 << 3 Partial removal organic matter (COD, TOC, colour) by limited feed water coagulation: 0.1 – 3 mg/l coagulant (as Fe/Al) 10 – 50% COD/TOC removalup to 95% colour removal Low energy consumption < 0.015 kWh/m3 permeate (based on TMP) Membrane Efficiency Pentair X-Flow UF

  12. XIGA™ dead-end UF

  13. Aquaflex™ UF

  14. Potable water plant Common wealth village – 1 MGD Commissioned : June 2010

  15. Potable water plants Surface water Potable water Inverness (1400 m3/h) Surface water Minneapolis (11.600 m3/h)

  16. Potable water plants Surface water Surface water Annemasse(300 m3/h) Potable water Sigey(1800 m3/h)

  17. Potable water plants Ground water PWN Heemskerk, The Netherlands2900 m3/h Keldgate, United Kingdom3700 m3/h Clay Lane, United Kingdom (6700 m3/h)

  18. Conventional Sewage treatment

  19. Water Reuse Applications Treated waste water finds wide applications in: • Industrial Process water • Fire fighting • Air conditioning & Ventilation • Green belt Irrigation • Cleaning • Flushing

  20. Process Flow Diagram of Sewage Reclamation Plant – 2 at M/s CPCL, Manali, Chennai . Sewage (FeCl3 + Poly) 2.5 MGR Sequence Batch Reactor Flash Mixer Clarifier Break Point Chlorination Reverse Osmosis Unit Stage 2 Reverse Osmosis Unit Stage 1 UltraFiltration Unit Multi Grade Filter Pressure Sand Filter Final Reject to Sea Degasser Tower Final Product to DM Plant Sewage Recycle scheme

  21. CPCL Case Study

  22. Waste water recycle plant CPCL 450 m3/hr UF plant IOCL Panipet 1050 m3/hr UF plant

  23. Waste water re cycle Plants Effluent reuse Sulaibiya, Kuwait (1500 m3/h) Melbourne, Australia (1250 m3/h)

  24. Waste water re cycle Plants Effluent reuse Beijing Olympics China Petro China

  25. MBR Technology

  26. Typical MBR applications • Thickly populated Urban areas • Capacity up gradation • Industrial complex • Shopping Malls • IT parks • Hotels and Resorts

  27. MBR Concept Pre-Treatment Bioreactor UF 1.Anearobic 2.Anoxic 3.Aerobic Permeate UF Raw Waste water • Biological removal of P • 2. De-nitrification (NO3  N2) • 3. Nitrification (NH4NO3) & removal of BOD/COD

  28. Advantages of External MBR Pentair Airlift MBR • Higher Flux • Low Energy consumption • Permeate Quality • Construction phase • Operators environment

  29. Quality of MBR product water • Pentair AirliftTM MBR has the tightest membrane pore size • (MWH title 22 report, 2006) • Permeate Quality • Turbidity of permeate: < 0.1 NTU • TSS levels: < 0.5 mg/l • BOD: < 5 mg/l • COD: < 20 mg/l • Microbial reduction - log 4 bacteria & log 6 Virus • SDI: < 3 • Highest effluent quality is an important factor for re-use purposes and future regulations

  30. Quality of MBR product water

  31. Quality of MBR product water

  32. MBR Installation Nokia 750 KLD plant March 2008

  33. Sea Water Desalination • Abundance of sea water • Reliable Source • Sustainable solution • Product Water to Potable standards

  34. Desalination Scheme

  35. Desalination Reference Palm Is lands Dubai (7700 m3/h)

  36. Desalination Reference Thames Gateway (189 MLD)

  37. Desalination Reference Nemmili : 222 MLD UF (Under construction)

  38. Conclusions • Conservation • Re use • Desalination • Resources are limited

  39. No Doubts. Pentair . Just Proof
