Shneel Mallik is a Barlett doctoral candidate and has created a special wall made out of ceramic tiles and algae. Called Indus, this wall uses dyes and chemicals to purify water. It is much cheaper then high tech water treatment solutions and can be made and maintained in areas where it is not economically sound to have those high tech options. The purifier’s tiles need replaced every few months by Malik and her team are working on making it last longer.
