DISCUSSION ON

FRESH PURIFIED WATER

Water is the most valuable natural resource that exists. Without water life does not exist. Fresh water makes up a very small portion of our total water supply. Eighteen percent (18%) of the world does not have any form of improved water supply. Much of the other 82% do not meet current EPA clean water drinking standards. As a consequence, 2.2 million people in developing countries, mostly children, die every year from diseases associated with lack of safe drinking water and inadequate sanitation. Traditional sources of spring or well water are becoming contaminated and the overall quality of water has deteriorated. The demand for some form of treatment of the water is increasing steadily. Every community in the world is faced with increasing demands on municipal potable water treatment systems and would like to have better water. Bottled water has become a major industry over the past decade in every city in the world because people want better quality water and do not trust the municipal treatment plants.

The Recovered Energy System™ produces a significant amount of steam. Once the energy has been removed from the steam it must be condensed and the condensate is then reused to make more steam. Traditionally, large cooling towers are used to condense the steam. These cooling towers require large amounts of fresh water for makeup water to replace the water that was evaporated. REI does not use cooling towers. Instead REI uses a multi-effect distillation (MED) system to condense the steam. At the same time the MED unit is condensing the steam it is also distilling an independent source of water. Seawater, river water, lake water, canal water or well water is pumped into the MED unit. The use of vacuum systems allow the low-pressure waste steam (steam that is at .34 bara) to distill 50% of the source water. The end result is that waste steam from the process is used to produce pure water and at the same time the water is used to condense the steam from the power plant. The plant will produce as much as 30,000 cubic meters (7,900,000 gallons) of pure distilled water per day at sea level and full power production. The flow of raw source water to support this output is 60,000 cubic meters based on using salt water at 3.6% salinity. If fresh water is used the amount of source water required is less. An additional 240,000 cubic meters of source water is used to condense and cool the final product. In total, 300,000 cubic meters of raw source water is pumped into the plant, of which 30,000 cubic meters comes out as pure distilled water with a total dissolved solids (TDS) of 10-20 ppm. The other 270,000 cubic meters comes back to the source 6 degrees C warmer and 4% salinity (based on using salt water feed). The pure distilled water produced can then be injected into the city water supply to supplement and improve the existing potable water supply. Alternatively, electrolytes can be added to the distilled water and be treated with ozone to produce purified water that meets bottled drinking water standards and can be sold as purified bottled water.

Fresh water makes up only a few percent of the world's total water supply. Compound that with the fact that our fresh water is being polluted from landfills, past dumpsites, and other factors and it is clear that the lack of safe drinking water is reaching a crisis situation in many municipalities.

Natural spring water is becoming hard to find and wells are becoming more contaminated. Most fresh water is not drinkable without some form of processing.

The Recovered Energy System™ can produce pure distilled water and even purified bottled drinking water using waste steam. Therefore the system incurs a very small energy cost to produce pure water, giving the system an economic advantage over other similar water treatment plants. The process will compete very favorably with any municipality that is currently treating water or desalinating water. This feature of the Recovered Energy System™ is not required for communities that have well water or spring water that requires minimal treatment. Since this is an optional component of the plant it can be used where it makes sense and can improve the economics of the plant but is not required for the project to be viable.
