Recently, a team of researchers from the University of California, Berkeley have developed a new method for disinfecting water using a combination of hydroponics and electrochemical hypochlorination. This new method is a potential game-changer for water sanitation, providing a low-cost and sustainable method of disinfecting water without the need for chlorine or other chemicals. The process works by using a combination of hydroponics, where plants absorb nutrients from water, and electrochemical hypochlorination, which uses electrical current to produce the disinfectant hypochlorous acid (HOCl). The HOCl produced by the electrochemical hypochlorination is then absorbed by the plants, where it breaks down into chlorine and oxygen, effectively disinfecting the water. This new method offers a simple and cost-effective way to disinfect water, and could potentially revolutionize water sanitation around the world.
