Finding water in thin air - M Ramya | TNN
Chennai: Going by the rate at which we are depleting our resources, some climate scientists predict that we will soon be left with nothing but thin air. But that’s no cause for panic. Enter atmospheric water extractor, which can not only get water out of air but also help you live in a natural air-conditioner.
With statistics that say only 3% of all the water available can be put to use, researchers say it’s time mankind looked at the only perennial source of water on earth–the atmosphere. SS Sivakumar, inventor of the Akash Ganga, the country’s first indigenous atmospheric water extractor (AWE), says, “The roots of the technology were made available even 30 years ago.” So he started thinking up a solution to man’s water problems in February 2004 and came up with Akash Ganga, an AWE that follows nature’s principles.
The AWE draws air from the atmosphere into a cold space, where the vapour is transformed into water through heat exchange, just as in natural rainfall. Compressant refrigerant gas moves through the condenser and looses both pressure and heat.
It then passes through copper pipes and capillaries, into the evaporator, where it chills the fans. Fresh air is induced through the air filter into the evaporator by a fan. In the chilled ambience of the evaporator it loses moisture. This pure water is collected in a stainless steel container and then transferred through stainless steel pipes to a container where it is filtered and stored.
AWEs like the Akash Ganga Water Creators work most effectively in regions that are warm and have high humidity levels, making them an ideal experiment in Indian coastal cities like Chennai. “So far 150 to 200 AWEs have been successfully set up in homes and offices in and around the city, including the Institute of Epidemiology in Chennai. In such a product the challenge lies in maintenance. We have put in place a service network that regularly cleans the filters and replaces parts,” said one of the directors of Akash Ganga TM Shyam Sundar.
“As it apes the natural condensation process it sounds like a good option, but we have to look at the economic viability and manufacturing costs of such potable water,” said K Karunakaran, director of the Centre for Water Resources in Anna University. Sivakumar says that by producing 1 litre of water with .46 Kwh the AWE can compete with industry standards in viability and that the purity levels are well within the permissible limits .
The advantages of the AWE over reverse osmosis treatment, which is gaining a rapid following in drinking water starved Chennai, is that there is no effluent unlike the reverse osmosis process which releases effluents and where the effluent ratio is likely to keep rising as groundwater level is depleted. Studies have shown that the rate of recharge of groundwater is 60% of the rate of extraction, which means the earth requires three years of good rainfall to make up for one year of water extraction.
“The market is ripe. We are poised to sell 2,600 water creators this year with a projected turnover of Rs 13.6 crore,” enthuses Shyam Sundar. With all these arguments to back it up the AWE technology seems an idea whose time has come.
