Swedish green process to remove dangerous textile chemicals

A new study from Lund University in Sweden claims that a green process can clean up the most dangerous chemicals that are used in textile dyes and then dumped into rivers and farmland. The technology was developed by Dr. Maria, a biotechnology doctoral student at Lund University, using fungal enzymes and bacteria from textile industry drains and municipal wastewater treatment plants.
Maria said that the invention of this technology was that she combined two different purification processes, biological and chemical processes, before finally breaking through. “First, microbes break down the dye in the reactor. This biotechnology is the most important step. However, to ensure that the water is completely purified, it also requires the use of some chemicals. Under the action of ultraviolet light, a small amount of iron and Hydrogen peroxide combines to decompose the most difficult to decompose structure in dyes," she explained.
Some experts pointed out that in the long run, this technology is likely to be used in textile factories in India, China and Bangladesh. Compared with some previous methods using biological and chemical purification, this technology has been tested in several textile mills, and its environmental protection effect is obvious.
