Indus Wall Purifies Water with Algae

Oct-19-19 The innovative Indus Wall can filter toxic dyes and metals from polluted water through its network of vein-shaped channels.

The wall was created by a team from University College London, and is made up of modular ceramic tiles etched with channels that mimic the veins in leaves. The channels are filled with algae suspended in a hydrogel derived from seaweed, which keep the algae alive and protected. As water filters through the channels, is it purified by the process of bioremediation—in which microorganisms break down environmental pollutants. In tests, one algae-based wall was able to reduce cadmium concentration by ten times in 45 minutes.
