ARTICLE - ATMOSPHERIC WATER GENERATOR

INAUGURATION OF AN ATMOSPHERIC WATER GENERATOR IN FORT-LIBERTE (Haiti Libre) -

Friday, Me Thierry Mayard-Paul, the Minister of the Interior, has inaugurated at St. Joseph Hospital in Fort-Liberte, a new piece of equipment, capable of producing pure water from the air.

The Minister explained "...this is a device that operates entirely with hydrogen and oxygen from the air, which extracts water from the air and produces a very pure water, after a dozen filter levels. So it's an Atmospheric Water Generator (AWG), and even when the humidity is below 35%, this machine produces water. This new equipment can produce about 200 liters per day [when the ambient humidity is 65%]. This means that patients, especially those suffering from cholera, dysentery etc... will be able to enjoy the benefits of pure water..."

Learn more about the Atmospheric Water Generators :
An atmospheric water generator (AWG), is a device that extracts water from humid ambient air. Water vapor in the air is condensed by cooling the air below its dew point, exposing the air to desiccants, or pressurizing the air. Unlike a dehumidifier, an AWG is designed to render the water potable. AWGs are very useful in locations where pure drinking water is difficult or impossible to obtain, as there is almost always a small amount of water in the air. The two primary techniques in use are cooling and desiccants.

Many atmospheric water generators operate in a manner very similar to that of a dehumidifier: air is passed over a cooled coil, causing water to condense. The rate of water production depends on the ambient temperature, humidity, the volume of air passing over the coil, and the machine's capacity to cool the coil. These systems reduce air temperature, which in turn reduces the air's capacity to carry water vapor. This is the most common technology.

Atmospheric water generators become more effective as relative humidity and air temperature increase. The rate at which water can be produced depends on relative humidity and ambient air temperature, and size of the compressor. The cost-effectiveness of an atmospheric water generator depends on the capacity of the machine, local humidity and temperature conditions, and the cost to power the unit.
