DCS Based Atmospheric Water Extractor For Domestic Use
Abstract
Availability of fresh water, which is fit for consumption,
has become a major concern due to its rising demand with rapidly
increasing population. Also, there is high possibility of water,
available at reservoirs, getting contaminated while transportation. A
partial solution to this is to find new renewable sources of water, one
of which is atmospheric water. It is the water present in air in the
form of vapour which gets added to atmosphere by natural process of
evaporation. The air containing water is termed as humid air and the
measurement of the extent of humidness of air is termed as humidity.
Coastal areas have the highest humidity values. This water, when
extracted, can serve as a secondary source of water to people living in
coastal areas. This would reduce the stress of water requirement on
the reservoirs. The process of liquefaction of water from air is called
condensation. It is done by lowering the temperature of air below its
dew point, which is the temperature at which air gets saturated by its
water content. There are machines called atmospheric water
generators which use this process to extract water from air. The water
is pure and safe for consumption. However, there are certain
disadvantages of which one is their high power requirement per litre
of water extracted. The goal of the industry is to reduce power
requirement and increase yield of water of these machines. There are
various applications of these systems such as for domestic
consumers, in healthcare facilities, in military establishments, in
industrial facilities etc.
