Bengaluru: Bengaluru-based InnoDI Water Technologies Private Company has come up with an innovative technology called Capacitive Deionization (CDI) to purify water.
This technology helps treat ground and surface water by reducing the amount of reject water and help retain essential minerals in the liquid and meets World Health Organisation standards.
It is said that in current water purification technology methods nearly 60 percent of the raw water is wasted as a reject during purification and the rejected water goes down the drain.
“Using CDI technology the water wastage is only up to 20 per cent water and unlike the Reverse Osmosis (RO) process, which takes away majority of the minerals from water, the CDI technology helps in removing all toxins like Fluoride, Nitrate, Arsenic etc, while retaining the desired levels of minerals required for our human body like calcium, magnesium etc,” explained Vijay Sampath, MD, InnoDI.
In CDI technology water is sent between carbon-based electrodes at low pressure and a potential difference is applied during the water flow, to remove ions present in water. These ions get absorbed to the oppositely charged electrodes causing their removal and the whole process does not use any chemicals. The cost of operation is very low and it takes just 10 paisa to produce a litre of purified water,” Sampath said.
He added that the company holds the global patent for CDI technology.
Prof T. Pradeep from IIT Madras, who has validated the CDI technology, has highlighted the ability of this technology to conserve water, its low operation cost and advantage of retaining the adequate minerals required for the human body.
InnoDI is an IIT Madras incubated company, Vijay said and on the future focus, he mentions that they have installed more than 150 machines across India, with the help of well known NGOs and business organisations.
The aim is to bring to market one of the best and most industrialized CDI solutions that can make a big social, environmental and nutritional impact on the society at large, he said....
