Across the world, Arsenic-contaminated ground water is one of the most concerning forms of water pollution. According to a study in 2007, more than 137 million people across over 70 nations are exposed to this problem. However, a team of researchers from Australia is now endeavouring to address this issue, building a filtration system using only recycled parts. This could probably be the cheapest and the most flexible technology that can be employed to put a check on this alarming problem.
Right now, the methods used for elimination of Arsenic from ground water include the use of Reverse Osmosis, a water purification process that removes harmful ions, molecules, and large particles that are difficult to be broken down from drinking water.
A special team from the University of Technology Sydney (UTS) has come up with a new low-cost filtration system, which costs $500,000, to get rid of Arsenic and produce clean drinking water. Distinguished professor of Indian origin Saravanamuth Vigneswaran and Dr. Tien Vinh Nguyen from the faculty of Engineering and IT are responsible for this initiative, and they employed this technique in Vietnam's Red River Delta.
The lead researcher Vigneswaran told the UTS Newsroom, "There are three key components to this system: an organic membrane, a tank/drum in which the membrane is inserted, and an absorptive cartridge made from locally available industrial waste products. This sustainable system will both maximise locally sourced resources and minimise arsenic waste and environmental pollution, improving health and quality of life."
This project could soon create plenty of employment opportunities in the locality once it is out for manufacturing, and consequently, it can be produced, installed, and maintained by the dealers. The team at UTS has been working hard for this project over the years, and a quite a number of papers have been published on the same.
