This powder helps make water cleaner, sticking to dirt and separating it from the water.
The product is called PolyGlu, which is a coagulant made from fermented soybeans. It mixes with dirt and pollutants, causing the dirt in the water to separate and sink.
One gram can treat up to 5 litres of polluted water, which could help improve water quality in third world countries. However, the water is still not fully purified and still requires further filtering to be safe to drink.
A self-contained tank is also available for use in emergencies when water supplies are disrupted.
