2.2.4 Air to Water Technology
To generate potable drinking water from condensed air.
Atmospheric water generators – Dehumidification/condensing technology that extracts water from the humidity in the air and sends it through a multi-stage filtration process including carbon and UV sterilization. The result is pure drinking water.
Air with its humidity is drawn into the atmospheric water generator and is immediately sent through an electrostatic air filter to remove micro particles and dust from entering the appliance. The air then passes through a condenser with temperature regulated evaporator coils that then generates the water from the air molecules. The water then progresses through a multi-stage filtration process to remove dirt, ammonia, chlorine residues, organic compounds, heavy metals, bacteria, etc. from the water source. In addition to the filtration system, the water is sent though a UV lamp sterilization tank and mineral filter to eliminate bacteria growth and to input healthy minerals back into the water.
Atmospheric water generating is cost efficient and uses a minimal amount of energy. Costs are dependent on local electricity costs, however, a gallon of water costs approximately 10 cents to produce. Unit costs range from $1,200 to $240,000 depending on the capacity of the unit. (Source: www.airtowatertech.com)
Prevents looming fresh water scarcity
Reduces transportation for inland areas
Increases availability for areas with lack of a clean water supply
Reduces plastic waste
Generators are most efficient in warm areas with high humidity. Most systems require a minimum of 35% humidity to operate and produce water effectively. They are available for both residential and commercial applications and should be located outside on building roofs or on ground level. Based on the unit size and weight, additional structure may be required.
