Scientists at MIT have created an electrochemical process able to selectively get rid of organic pollutants in water, which can be harmful even in minimal amounts. Typically, a lot of energy or chemicals are required to remove dangerous contaminants, but this new process is different, relying on a special combination of low voltages and pressure to pull out harmful toxins. With such a low amount of energy needed, the process could help people in developing countries obtain water without those unhealthy compounds.
