Tastes better than bottled water: firm

Swelect Energy Systems Ltd. (formerly known as Numeric Power Systems Ltd.) has unveiled ‘Source,’ a hydro (solar) panel to provide pure drinking water using sunlight and air, said a top official.

“For this, we have partnered with U.S.-based Zero Mass Water,” said R. Chellappan, managing director, Swelect Energy Systems Ltd. “By using hydropanels, we are eliminating plastic and water waste of bottled and filtered water.”

Source is a combination of solar PV (photovolatic), material science and other technologies. It is a standalone product and can work anywhere — on top of the building or on the ground. It can be installed immediately. It doesn’t require any electrical input.

Absorbing water vapour

He said water vapour from air is drawn into Source through fans, following which special materials absorb the water. The vapour is collected as the air flow passes through a condenser, then flows into a reservoir where it is mineralised with calcium and magnesium. Water is pumped through a polishing cartridge before being delivered to a dispenser. “The water will taste better than bottled water and the total cost of ownership will be cheaper when compared with bottled water,” he said.

The price per panel will be ₹2 lakh and it will generate up to five litres of water per day depending on humidity and sunlight, he said. The panel would last for about 15 years. There is also a storing facility underneath a panel that can hold 30 litres.

“The product is very similar to solar PV. It is scalable and we can do one panel per home to 100 panels for a village,” said Robert Bartrop, executive vice-president– business development, Zero Mass Water.

Swelect plans to sell Source panels to government-run programmes on water, retail and institutional markets through its network of channel partners. The company will target primary health centres, schools, large villas, resorts and water-starved places.
