2 Agenda Effluent reuse for Power Plants MBR Technology Maximizing reuse potential Zero Liquid Discharge Next frontier GE Water 2

3 Wastewater Reuse opportunities exist within Problem/Source Solution/Technology Value Generation Cooling Tower Blow-Down True-Sense/GenGard UF + RO/EDR + EDI Reduce blow-down Cooling Tower Makeup/Boiler Feed Boiler Blow-Down Optisperse UF + RO/EDR + EDI Reduce blow-down Cooling Tower Makeup and/or Boiler Feed Demineralization Waste/RO Reject Ash Pond Wastewater UF + RO/EDR + EDI Seeded slurry evaporators One-Stage Filter + RO/EDR Reduce blow-down Cooling Tower Makeup and/or Boiler Feed Reduce blow-down Cooling Tower Makeup 3

4 and from outside Municipal Sewage OBJECTIVES Remove organic and ionic impurities Recover water/reduce inlet quantity Reduce waste volume Waste Treatment Tankage Pre-Treatment NF/RO/EDR Boiler Feed Service Water Cooling Tower Flushing/ Gardening Immense reuse potential for India s current municipal sewage generation of > 38,000 MLD! 4

5 Membrane Bio-Reactor: Sewage to Boiler feed! Conventional AS Process Primary Clarifier Activated Sludge Secondary Clarifier Sand Filter ZeeWeed MBR Process Activated Sludge Sludge Digestion To Sludge Dewatering To Sludge Dewatering Reinforced UF membrane: Absolute barrier for treatment/removal; Higher life Higher MLSS: Smaller footprint/layout ideal for retrofit Improved control: Improved degradation of complex organics & nutrients Proven Process: Minimal pre-treatment and fewer cleaning chemicals Modular: Easy to expand Automated: Operational simplicity with potential for remote monitoring 5

6 Significant Footprint Reduction Membrane bio-reactor plant Conventional plant 6

7 Municipal Wastewater Reuse for Power Plants Challenge: Solution: Insufficient fresh water for Power Plant consumption Municipal wastewater reuse using UF + RO E.C. Katowice, Poland Power plant using municipal WW secondary effluent as feed UF + RO treatment for cooling tower makeup water 5,600 m³/day. Commissioned Jan 1999 NTU < 0.05 mg/l, SDI <1 Redlands, California, USA Capacity: 22,700 m 3 /d (average daily flow) 25,000 m 3 /d (maximum daily flow) 7,600 15,100 m 3 /d MBR permeate used for Cooling Tower make up, boiler feed, etc. Commissioned: June
