Team develops system to strip persistent textile dyes from wastewater and aims to scale compact treatment units for factory effluent streams

MOSCOW — Researchers at South Ural State University (SUSU) say they have developed an electrochemical reactor that can decolourise persistent textile dyes in wastewater without additional chemical reagents.

The team, working with TV BRICS partners, reports that a synthetic dye solution became completely colourless within 90 minutes in laboratory tests and that performance remained almost unchanged over 15 consecutive treatment cycles.
