Textile dying is one of the most environmentally hazardous aspects of the textile industry. During dying, harmful chemicals that are difficult to break down are released, all too often into rivers and agricultural land. However, Maria Jonstrup, a doctoral student in Biotechnology at Lund University, has developed a new, environmentally friendly purification process which leaves only clean water. The findings are presented in Maria Jonstrup's thesis.
The research is so far only research, and has therefore only been tested in the laboratory, but Maria Jonstrup is optimistic about its future potential.
"First, microorganisms break down the dyes in a reactor. This biological step is the most important. However, to be certain that the water is completely purified, I also use some chemicals. Small amounts of iron and hydrogen peroxide in combination with UV light break down even the most difficult structures", she explains.
