Light shall be used to clean drinking water

Water is life. With more than 60 percent clean water used for irrigation purpose, the nation has to think about preserving clean water for drinking and irrigation purposes. Many research and technologies have come up to improve drinking water and free it from bacteria and germs.

A Delhi-based organisation too have profound a fresh water storage system.It is designed to store fresh rain water and avoid it from Saline. Preservation and cleaning of water has been in the priority list by government and research institutes.

Likewsie a method of cleaning drinking water with light is being tested and developed at The University of Alabama with the hope of creating a product available for homes and businesses.

LiTeWater, a company spun off from the technology, will be one of five teams competing in the Alabama Launchpad Startup Competition Dec. 10 in Huntsville.

Cleaning drinking water from a faucet with ultraviolet light, along with standard filters, could not only remove chemicals, but potentially harmful viruses and bacteria. Commercially-available filters for homes and businesses use activated carbon and other minerals to remove contaminants, but they do not disinfect the water from pathogens.

“LiteWater is a mini water treatment plant for a faucet,” said Ben Bickerstaff, co-founder of the company and a graduate research assistant with the UA Office for Technology Transfer. “The technology uses UV lamps to disinfect harmful pathogens from water. To date, we have blown past EPA standards, the gold standard, for clean drinking water.”

While water treatment facilities disinfect drinking water for customers, the water travels through pipes to homes and businesses. There are more than 100 million miles of drinking-water pipes in the United States, and the majority has been buried for more than 30 years, some since the Civil War. That has some systems struggling to maintain the aging infrastructure on small budgets.

Small water systems, particular those in rural, economically disadvantaged areas, often have subpar maintenance and infrastructure investments as they serve a small population over large areas. About a quarter of Alabamians receive drinking water from small water systems and another 12 percent use private water wells that don’t have the advantages of large, municipal water systems, according to research by LiteWater.
