An interdisciplinary team led by Dr Brenda Parker, Professor Marcos Cruz and Shneel Malik, created ‘Indus’, a tile-based, modular bioreactor wall system, based on the principle of bioremediation. The structure is designed to hold algae-laden hydrogel for cleaning heavy materials from wastewater.
Inspired by the architecture of a leaf, water flows over a series of vein-like channels containing algae prepared in a seaweed-based hydrogel. Pollutants such as cadmium are sequestered by the algae and the hydrogel can then be processed to recover heavy metals safely.
The project meets the need for a simple, scalable and a sustainable system that can treat heavy metal contaminated wastewater on a local level.
Indus was displayed at the A/D/O exhibition space in New York, earlier this month and voting is now open for the public to support their favourite proposal.
