  • 12. Plimmer® Operation Company Confidential 12 • The Technology used is called Capacitive Deionization (CDI) • This is a non Membrane technology where the ions are attracted to a pair of electrodes as water flows. – Requires very low pressure – results in low power consumption – Reduces water wastage since water is not pushed into a membrane under high pressure • Technology has 12 patents in terms of number of electrodes, coating on electrodes and electronics required to handle the process. • No chemicals required for treating water • Electrodes require just 1.6 V charge to operate – providing an option to run on Alternate energy sources

The water void of these salts and metals come out of the system Water is then flushed between the electrodes and the wasted ions are flushed to drain. The Polarity is reversed back and the Ion removal process (Step 1) starts again With more and more ions sticking to the electrodes, they become saturated – when this happens, the system automatically changes the polarity. The ions sticking to the electrodes fall off. Step 1 Ion removal Step 2 Regeneration Step 3 Flush

  • 21. Post Treatment – Citric Acid Cleaning Company Confidential 21 • Patented process for cleaning cells • This is a patented process for pro-actively cleaning cells to avoid excess calcium build up in cells • This is done automatically at end of every production cycle • We can set production cycles to 5 / 10 / 20 hours with rest period of 1 / 2/ 4 hours • At start of rest period, Plimmer® automatically takes in small quantity of CA solution to clean cells. This will be flushed out at start of production • CA is environmentally friendly – Organic Acid with no discharge hazards • This process ensures long life of electrodes • Solution can be prepared locally at the regional support centre

Post Treatment – Citric Acid Cleaning Company Confidential 22 Tests were performed on the long-term efficiency making daily “self-maintenance” with the special maintenance solution finalized by Idropan In normal work WITHOUT the use of citric acid the pressure drop (fouling index) increases rapidly during the work period From tests carried out there is a precise relationship between the Temporary Hardness and the effect of fouling of the cell. 0,1 0,15 0,2 0,25 0,3 0,35 0,4 0,45 0 5 10 15 20 Pressure(kgf/cm2) time (Hr) Fouling Index Test conditions recommended by European legislation : Inlet water: Hardness300 ~ 340 ppm, TDS 450 ~ 500 ppm, IEC60734 Days before cell cleaning WITHOUT Self maintenance

  • 24. Plimmer® saltless Cdi softener concept
  • 25. System Recirculation Pump Drain Conductivity SensorSolenoid Valve Solenoid Valve Plimmer® Storage Tank Beginning of the day
  • 26. Water is beginning to be used
  • 27. Water demand stops in the home but the Plimmer® continues to treat water in the tank
  • 28. Plimmer® regenerates as needed
  • 29. Tank is almost filled…
  • 30. Tanks is full and Plimmer® shuts off automatically
  • 31. Plimmer® goes into maintenance mode and initiates self cleaning (set time off peak)
  • 32. Plimmer® high salinity concept
  • 33. Our idea – high salinity conductivity reduction system
  • 34. Two phases – Production and regeneration • Cells work in twin mode: while one is producing water, the other is regenerating. • The interval is very short: about every minute cells switch. • Until good water is not at the desired conductivity, it continues flow in the plug flow and in the cells. • If waste water has not reached the desired minimum conductivity, it stays in the regeneration plug flow. • System design helps energy recovery and lower waste water volume
  • 35. Production phase (1) When water coming out from the cell reaches good conductivity, it is delivered to the outlet. Same amount of new untreated water is added to the plug flow
  • 36. Production phase (2) Water still goes to the outlet until it goes over the specified conductivity.
  • 37. Production phase (3) When the conductivity is exceeded, water starts to recirculate. In some stages the quality will go down to the desired value.
  • 38. Production phase (4) The cell continues to treat water. The water will not mix and inside the tank you will have different conductivity areas.
  • 39. Production phase (5) The cell continues to treat water. The water will not mix and inside the tank you will have different conductivity areas.
  • 40. Production phase (6) When the water out of the cell is not treated, it means that the cell is exausthed and regeneration need to be started.
  • 41. Regeneration phase (1) At the beginning circulation will move high salinity water in cell
  • 42. Regeneration phase (2) At this time ions begins to be removed from cell electrodes
  • 43. Regeneration phase (3) Removal of ions give raise to a voltage over cell terminal this energy will be forwarded to other cell by electronics
  • 44. Regeneration phase (4) When all ions are discharged from electrodes conductivity increase will lead to some waste
  • 45. Regeneration phase (5) As soon as conductivity will be lower than set point circulation will begin and cell will be washed from PF tank liquid
  • 46. Regeneration phase (6) When water is at the same conductivity of income water, cell is clean and production can begin again.
  • 47. Twin operation • The above explanation relates to a single cell but actually while Cell 1 is in operation Cell 2 undergoes a regeneration so continuous operation and energy recovery are possible
  • 48. Overview of results
  • 49. Goals achieved • System will do energy recovery • System will waste a desirable amount of water (based on specified conductivity) • Treated water with a specific quality that can be set from user
  • 50. Key Aspects of Plimmer® technology
  • 51. Understanding of What CDI can handle and what it cannot Company Confidential 51 • What it cannot handle • Any particles that cannot be charged • Silica & Clay • How we handle this: • We first assess water condition with an SDI kit to see levels of Silica and clay • Have a pre-treatment process before the inlet tank to coagulate this and filter it • May not be required at all centres – only base on water conditions • What Can go wrong • Calcium fouling of the Electrodes • This happens when the electrodes are not cleaned properly with CA solution regularly • If dosage is less or if the CA solution is not properly managed • How we handle this: • Automated CA cleaning at end of every production cycle • Facility to set the dosage timing depending of water quality • Extra Acid Wash button for regular routine maintenance • We will control and supply the CA solution through our regional centres • Cleaning cells in labs (Done only when Proactive treatment described above fails for any reason)
  • 52. Understanding of What Plimmer® can handle and what it cannot Company Confidential 52 • What Can go wrong • Bio-fouling of the cells • Bio-fouling is common problem in all technologies – unless treated proactively • How we handle this: • Ozonating the inlet tank • Using media that are not prone to bacterial contamination • Treating cells in labs (Done only when Proactive treatment described above fails for any reason)
  • 53. Conclusion & Summary Company Confidential 53 • We have developed a system with a lot of thought for managing drinking water in villages • Plimmer® is the only proven solution available with such high levels of automation and consistency • Plimmer® is the only system that can take care of all known contaminants in water • A single system will ensure consistency of maintenance and reduce costs of management • Clever automation ensures pro-active management of technology – reduced stoppage time of plants • Proven technology backed by global patents
