Demonstration of a low-cost water purification technology using BARC ‘membrane’ was held in Madurai on Monday.

Small-scale entrepreneurs were encouraged to manufacture a new low-cost water purification technology with a ‘membrane’ developed by Bhabha Atomic Research Institute (BARC), here on Monday.

BARC and Madurai District Tiny and Small-Scale Industries Association (MADITSSIA) collaborated to conduct a one-day workshop for explaining the need to manufacture the parts necessary for this water purification solution.

Scientists and businessmen explained to 60 entrepreneurs the potential in producing this ‘membrane’ in Madurai.

“This unique membrane-based portable water purifier does not require electricity or regular replacement of parts. It helps in saving treated water and requires minimum maintenance. Water can be supplied to at least four other households with the installation of each portable purifier. It is a sustainable and profitable solution,” said J. Daniel Chellappa, Senior Scientist (Technical Coordination Wing), BARC.

Inaugurating the event, Revenue Minister R.B. Udhayakumar said, “People avoid such investments because they believe they are costly.”

The cost of setting up a basic purifier plant (producing ultra filtration membrane) for Madurai Corporation areas would amount only to ₹3 lakh, a negligible amount, according to Mr. Chellappa.

A plant required an air-conditioner, a purifier, a 200-square-foot room and one person to ensure temperature control, he added.

There were five such membranes created for various purposes, including a ‘tabletop’ model for double filtration to be used in rural areas, a charged nano-filtration system and a spiral system for desalination. “Investment increases proportionately with each model. One of the purifiers also ensures that essential minerals in water are protected,” added Mr. Chellappa.

MADITSSIA president K.P. Murugan said Madurai had immense potential in this area. “The field offers great marketing potential. The city can become a hub and sell it to different parts of the country. We are focussing on small entrepreneurs to take up manufacturing as large players will monopolise the market and hike the product cost,” he said.
