AltelaRain® can desalinate or remediate any kind of water AND do so completely “off-the-grid”, using only Solar Thermal (ST) energy (or solar combined with wind energy).

AltelaRain System desalinating water in remote locationsPresent commonplace water desalination products (e.g. Reverse Osmosis [RO], Mechanical Vapor Compression [MVC], etc.) require large amounts of electrical energy supplied by the electrical grid. Conventional large-scale water desalination is therefore either impossible or impractical in many arid and remote locations, i.e., any location where high-quality, high-power electricity is not available. In such locations, water desalination is then only possible by bringing in electrical generators powered by gasoline, diesel, or other fossil fuel to generate such high-power electricity.

The need for such fuel then makes water desalination impractical – at best – at those locations, because of both the high cost of the fuel and the need to continually transport it to the location.

Altela has unique technology that uses large amounts of waste heat generated from Solar Thermal energy in place of this fossil fuel.

AltelaRain and Solar ThermalThe AltelaRain® technology recaptures energy 3 times, and thus makes 3 gallons of pure distilled water from the energy required to make 1 gallon from conventional thermal distillation. And, Altela is the only water desalination company in the world that uses no pressure (and therefore 99% of the energy is NOT from the electricity required to operate high-pressure pumps.) It is therefore perfectly married to the burgeoning sister industry of Solar Thermal (ST) – passive solar – because Altela uses (for free) the two-thirds energy of passive solar that presently now gets wasted as low-grade low-temperature waste heat.

Such low-grade waste energy is available for water desalination when co-located with such an ST location throughout the southwest U.S. in states like New Mexico, Arizona and southern California, as well as abroad in areas such as the Middle East.

Partnering with a Solar Thermal company, an Electricity-Generating Plant with a co-located Brackish Water Desalination Plant may be economic – whereas presently neither one would be economically viable on its own. Why? Because ST alone wastes two-thirds of the passive solar energy it collects – whereas we can use that to drive our desalination process virtually for free – and together make arid locations like New Mexico deserts and Masdar City in the Middle East viable for both alternative energy electricity and water desalination.
