  • 1. VERY INTERESTING, TOTALLY NEW PROCESS TO GET PURE WATER OUT OF SEAWATER This is a direct imitationof the natural process of producing pure rain water out of seawater. The present Reverse Osmosis is expensive, impractical, and here is the result, huge lands next to sea shores are left deserted. www.naturalseawaterdesalination.com mail@naturalseawaterdesalination.com 1 587 716 7564
  • 2. By making a simple imitationof what the Lord did for seawater desalinationwe will be able to get PURE WATER FROM SEAWATER CHEAPER THAN CITY WATER. Sooner or later this process will be the only acceptable process for the production of pure water as it does not consume any energy to complete the separation of pure water;the energy is extracted from the bulk of seawater cooling it. This is also an extra proof of the ultimate wisdom of The Creator. The NEEDED EQUIPMENT IS MUCH, MUCH SIMPLER THAN REVERSE OSMOSIS. The equipment is similarto a very simple industrial water cooler. Air dischargedby the large fan placed on top of the water cooler is carrying extra water vapors which can be condensedby the same water cooledat the bottom of the water cooler. Our Natural Seawater Desalination units are less than half the price of comparable reverse osmosis units. www.naturalseawaterdesalination.com mail@naturalseawaterdesalination.com
  • 3. Our expensive today setup for seawater desalinationhave imposedthat vast lands next to sea shores are left behind deserted, while our Natural Seawater Desalinationunits can allowus to cultivate all our deserted sea shores. To all dealers of reverse osmosis:Come and see for yourself how simple it is. The core equipment needed is a centrifugal, or axial air blower, we are availing it at a very, very low price. Surely the concept presented here is very simple and is a powerful tool to help this human race make use out of all these deserted sea shores. www.naturalseawaterdesalination.com mail@naturalseawaterdesalination.com
  • 4. In a water cooler, air is flowing through water sprays. Air gets saturated with water vapors, and water gets coolerby vaporization. Next we take these two streams to exchange heat in a heat exchanger. We will get pure condensedwater at the bottom of heat exchanger.
  • 5. COMPARISON WITH REVERSE OSMOSIS. No expensive equipment: No excessive high pressure pumps, no expensive membrane elements. No increase in pressure drop: After using membranes elements for a short while, pressure requirements start to increase. No decrease in product flow rate: Still after using membranes for a short while the product output flow rate starts to decrease.
  • 6. No dangerous chemicals added: Reverse osmosis consumesconstantlysulfuric acid as anti-scaling agent. On the contrary: Very simple design, at very mildconditions allowing very cheap materials to be used. Heat exchanger operates at a temperature lower than 50 C allowing the use of plastic piping. Water cooler packing can be very simple Rashig rings which are simplya plastic pipe cut into small equal segments. www.naturalseawaterdesalination.com mail@naturalseawaterdesalination.com
  • 7. Energy requirements for different desalination processes are given for your reference: Energy needed to separate pure water from sea water for room temperature evaporation (Natural Seawater Desalination) is ZERO, howeverfor: 1- By Multi FlashEvaporation, or Multiple Effect Evaporation: By considering the energy needed for evaporation, and initial seawater at 50 degrees centigrade: = (50 kCal/kg + 540 kCal/kg) X 4.18 kJ/kCal = 2466 kJ/kg = 2466 MJ/m3.
  • 8. 2- By Reverse Osmosis: Van’t Hoff Equation defines the osmotic pressure (π) to be equal to (i) Van’t Hoff Constant (which is practically the number of ions of the salt, for dilute solutions) X the molarsolute concentration per liter(c) X the universal gas constant X the temperature in Kelvin(similarto the universal gas equation). Π = i c R T. A rough estimate for sea water osmotic pressure (considering the salt to be only NaCl) at 42,000 ppm: π = 2 X 42/58.5 X 0.082 X 293 = 34.5 atm, this is the theoretical osmotic pressure, without considering membrane fouling, or any pretreatment and after-treatment equipment. To bring 1 m3 to a pressure of 34.5 atm P kW = Q h ρ g = 1 m3/hr X 34.5 atm X 10.33 m of water X 9.81 m/s2 X 1000 kg/ m3 / 3.6 X1,000,000 = = 0.97 kW Work needed for 1 m3/hr = 970 W X 3600 sec = 3500 kJ/m3 This is the minimum theoretical energy consumption, actual consumptionis not less than twice this value to account for membrane fouling.
  • 9. Energy consumption: our process consumes less than 3 kWh/ m3, compared to 5.6 kWh/ m3 for reverse osmosis. We are unable to build small units for single familyconsumption(1500lit/day), as the unit occupies a large volume of more than 3 m3 which represents an obstacle in shipping. Shipping cost becomes more expensive than the unit itself. Consequently we are limitedto units not less than 20,000 lit/day (20 m3 /day). The equipment comes with an inlet filter. In case of surface brackishwater containing calcium salts (hard water), then we will provide a water softener for very low extra charges. We would like to clarify that our seawater desalinationunit is practicallymaintenance free, with practically no renewable items. www.naturalseawaterdesalination.com mail@naturalseawaterdesalination.com 1 587 716 7564
