Status of World Water Shortage Because of the increase of the world's population, especially countries like Indonesia, Vietnam, India, and etc. under rapid economic growth, significant reduction of water use per capita is happening. The deepening of uneven distribution of global water resources, is occurring significant water shortages in specified countries. (1/5 countries around the world, 3 billion people) Large amounts of sewage and waste water generated by the rapid industrialization are contaminating the ground and the underground water. The reduced amount of drinkable clean water causes various waterborn diseases. (each year, 5 million people killed) Now, we have to recognize the need for high efficient distiller equipment P_2

RO Conversion Method Reverse Osmosis (RO) Filter System and Actual Operating Environment in Korea : - Need for clean sea water : Serious sea water contamination issue in the island regions in the west and south seas ->Demand for tube well - Must Operate Continuously : Intermittent operation, frequent filter replacements, unexpected increase of cost. - Bacillus Not Eliminated : Dosing of chemicals (condenser, reducer: sulfuric acid, chlorine), increase of operating cost - Pre and Post Treatment Systems / Professional Operator Required : Accident and risk in the handling of dangerous chemicals by non-professionals, operating cost increase P_4
Evaporation Conversion Methods Evaporation(MED, MSF, MVR) Distiller System : - Irrelevant to the cleanness of sea water and any source water -> Appropriate for west sea/south sea, flood swept area(muddy water) in Korea - No special need for pre and post treatment systems/dosing of chemicals/parts which need to be replaced periodically -> Reduced operating cost - No need for sterilization (chlorine) -> 100% automatic high-temperature sterilization (Absolutely no virus!!!) - Non-corrosive material/transportable small package/automation -> Long life, possible to move to an arbitrary location Vacuum pump Steam Steam Cooling water Raw Water Pure Water Multi Effects Distiller (MED) P_5

Water Recovery Rate and Power Consumption Type TDS(ppm) Recovery Rate(%) Power consumption (kwh/ton) Remark Sea Water 15,000~50,0 00 50 ~ 85% 30.3 ~ 63.3 * TDS : Total Dissolved Solid Brackish Water 1,500~15,00 15 0 85 ~ 98% 27.0 ~ 30.3 Underground Water More than 90% It depends on the amount of TDS The input raw water can be concentrated until max. 100,000ppm(=10% density) by MVR Distiller Water recovery rate = {1-TDS/(100,000ppm)}*100 000 Example : in case of TDS 15,000 of input raw water Water recovery rate ={1-15,000/100,000}*100=85%, Rejected water rate : 15% It means we are able to extract pure drinking water of 85% from input raw water. Power consumption calculation formula, based on our experiences : Power consumption(kwh/ton) = 145/100 * (concentration)^2 + 27 Example : in case of TDS 15,000 of input raw water, concentration may be 1.5, expressed by percentage of density of impurity dissolved in water. Power consumption = 145/100 * 1.5^2 + 27 = 30.3(kWh/ton) 3(kWh/ton) P_21
