BATH – Technologies such as membrane-based nano-scale filtration are needed to treat the billions of tons of dye-containing wastewater which enter aquatic systems every year, according to a new study that calls for a new approach to pollution remediation.
Entitled 'Environmental impacts and remediation of dye-containing wastewater', it claims up to 80% of dye-containing industrial wastewaters created in low- and middle-income countries are released untreated into waterways or used directly for irrigation.
