HYDERABAD: Water conservation has been spoken about since decades but a project of Hyderabad-based Indian Institute of Chemical Technology (IICT) in collaboration with a city-based private company has gone a step ahead - generating water from air. The idea behind developing the machine known as Atmospheric Water Generator (AWG), an outcome of collaboration between IICT and Maithri Aquatech, is simple - to generate water by utilizing moisture available in the air, which is basically water vapour, that gets into air due to evaporation of water from various water bodies.
One AWG machine, which is as small as 3 feet by 8 feet can generate up to 1,000 liters of clean drinking water per day. Basic working principle of this machine is that it sucks air from atmosphere. However, water obtained through condensing of water vapour in air is not fit for drinking as it does not contain essential nutrients As air itself is polluted, mainly with particulate matter, two filters of 12 nd 1 micron size exist in AWG machine through which the sucked air passes and the particulate matter gets filtered out.
