DESCRIPTION
Dyes widely used in the textile, food and pharmaceutical industries pose a pressing threat to plant, animal and human health, as well as natural environments around the world, a new study has found. Billions of tons of dye-containing wastewater enter water systems every year, and a group of researchers say that new sustainable technologies including new membrane-based nano-scale filtration are needed to solve the issue, adding that legislation is needed to compel industrial producers to eliminate colorants before they reach public sewage systems or waterways.
