2008 EWP Technical Presentation

  1. 1. Cleaning our Waters www.AquaEWP.com
  2. 2. Capacitive Deionization (CDI) • Hybrid of CDI and (patent pending) EDX Flow Out – 3 more ways to Purify – 3 more ways to Flush • In refinement for 10 years Conducto - r 1 Flow In Spacer VDC + • Benefits of EWP X3 Electrode – More water produced daily – Faster regeneration time – 25% less power consumed
  3. 3. General Features of EWP • Less pretreatment than Ion Exchange or RO • No chemicals • Purification varies with flow • One pass process - 80% purify • Cells in series for higher feed salinity to maintain purification • Recoveries of 80% to 96% (with waste recovery) • Cells never replaced, citric acid PM cleaning • Voltage or flow of cell can be varied to dial in taste
  4. 4. Sample Cell and Power Supply • Power supply 1.5 VDC Flow in/out • Cell ½ gpm net flow • 80% purification at 1,000 ppm TDS • Recovery at 80% • Power consumption 2 watt-hr per gallon per 1,000 ppm TDS
  5. 5. City Water Supply warehouse drinking water system 94% purification-6+ years in service System long term testing EWP in water cooler application -- San Antonio City Water (525 us) 55 50 conductivity us 45 40 updated with new power supply and EPROM board design 35 30 0 500 1000 1500 2000 days in service

  17. 17. Value Proposition • EWP has – Better taste • due to dial for taste feature and no salt in your water – Healthier • due to removing more primary pollutants than any other technology—softener doesn’t remove any – Lower cost (OPEX and CAPEX) • Features such as 80% recovery, Citric Acid Cleaning, small power use, no hassle warranty and service program – Easier to operate • due to solid state design, on-board TDS monitor – Peace of Mind • for removing all of the primary pollutants, having a salt-less softened water and no hasslbe warranty and service program – Green Technology • Due to no salt discharge
  18. 18. Water Genie Specifications 2 models 1000 ppm, 2500 ppm TDS Capacity 50 GPD Purification 80%+ of minerals and contaminants % Removal Waste 20% to 30% Feed Pressure 20 psig EWP size 6” W x 10” H x 6 “ d Electrical @110 1/2 amp VAC

  21. 21. Value Proposition POU • EWP has – Better taste • due to dial for taste feature – Healthier • due to removing more primary pollutants than any other technology – Lower cost (OPEX and CAPEX) • Features such as 70% recovery, Citric Acid Cleaning, small power use, no hassle warranty and service program – Easier to operate • due to low pressure, solid state design, on-board TDS monitor – Peace of Mind • for removing all of the primary pollutants, having a salt-less softened water and no hasslbe warranty and service program
  22. 22. Major System Components Mini-EWP creates the purified water Bladder Tank-stores the purified water Spigot (not shown)- delivers the purified water from the sink Install under your kitchen counter
  23. 23. Water Dispenser or Water Cooler • 2 gallon capacity, 50 GPD • Counter top appliance • EWP electronics on the inside • Sink hookup or permanantly to plumbing
  24. 24. Benefits of Using EWP • saltless water softener + more • 1/3 smaller size than RO • configured into countertop appliance, water dispenser, water cooler • designs at 2,500 ppm for POU/POE • scales small or large • 80%+ recovery • lower maintenance--cleaned with citric acid • no membrane replacement • One technology for contaminant removal such as with As, FL, Nitrates, Perchlorate • better tasting water--purification better with no TDS creep as with RO
