Industrial wastewater reuse_Anil Sharma_2013

  1. 1. Industrial Wastewater Reuse December 13, 2013 Anil Sharma, P.Eng Regional Leader – Process, APAC
  2. 2. Presentation Outline • General • ZeeWeed MBR Technology • Industrial Wastewater Reuse Case Studies • Automotive • Refinery/Petrochemical • Food & Beverages • Conclusions • Q&A
  3. 3. Global water challenges Availability • Deteriorating water quality • Increased industrial pollution Quality Environmental Energy • Growing population and industry • Climate change and draught • Stricter regulation on discharge/withdrawal • Water reuse incentives and mandates • Energy to increase ~30% by 2030 • Demand for water to increase ~40% Growing water scarcity and impairment
  4. 4. Types of Reuse Urban Reuse • Irrigation of parks, highway medians, golf courses, etc. • Commercial uses such as vehicle washing, window washing, etc. • Fire protection • Dust control and concrete production • Toilet and urinal flushing • Construction water Groundwater recharge • Aquifer reinjection • Subsurface infiltration • Surface infiltration Industrial Reuse • Cooling water • Boiler make-up water • Industrial process water Agricultural reuse Environmental and recreational • To create, restore, and/or enhance wetlands • Recreational and aesthetic impoundments eg. Ornamental ponds Reclaimed wastewater is an increasingly important source of supply 4
  5. 5. GE Water’s UF/MBR Membrane Technology Applications Core Membrane Technology Drinking Water • Municipal Water • Marine & Defence • Consumer (Retail) Sewage • Municipal Sewage • Water Reuse • Land Development • Marine & Defence Industrial UF Pretreatment Make-up water for: • Boiler feed • Cooling towers • Process water Industrial WasteWater • Membrane Bioreactor • Tertiary filtration • Water reuse
  6. 6. ZeeWeed Technology
  7. 7. MBR (Membrane Bio Reactor) & Tertiary Treatment ZeeWeed® MBR Simplified Treatment Process Wastewater ZeeWeed® Tertiary Filtration Process High Quality Effluent for RO Feed
  8. 8. ZeeWeed® MBR Influent Filtrate (Effluent) 10,000 to 15,000 mg/l Bioreactor Membrane (liquid/solids separation) Hi-Rate Biological Treatment • large capacity throughput • compact footprint • advanced treatment • simpler, more reliable process Absolute / Positive Filter • high degree of biomass/solids control • consistently high effluent quality • lower operator attention - less components 8
  9. 9. ZeeWeed® MBR Technology • Immersed • Hollow fiber • Outside-in • Ultrafiltration (UF) • PVDF (chlorine and oxidant-resistant) polymer 0.04 µm 9
  10. 10. ZeeWeed = Consistent High Quality Effluent Achievable ZeeWeed Treatment Results BOD5 < 5 mg/L TSS < 1 mg/L NH3-N < 0.05 mg/L TN < 3 mg/L* TP < 0.05 mg/L* Turbidity < 0.1 NTU SDI <3 * With appropriate biological design ** After disinfection 10
  11. 11. Industrial Wastewater Reuse
  12. 12. Specifics of Industrial Wastewater Reuse Treatment General Considerations! • Treatability of Wastewater or achievability of effluent requirements is always questionable! • Wastewater characteristics can be completely different from one application to next within same industrial segment
  13. 13. Specifics of Industrial Wastewater Reuse Treatment • • • • • • • • • • Extreme pH variations Non (readily) biodegradable fractions (COD, organic N) Nutrient deficiencies (N, P, ions) Extremely high influent concentration (COD, N, P, etc.) High solids concentrations (TSS, VSS)/ inert material high temperatures high/ low TDS inhibitory compounds or toxic compounds other compounds to be considered for design, e.g. sulphides Foulants/ Scalants (colloidal material, free oil, scalants) Piloting is an essential tool for accurate design
