Overview of Some Colour removal Technologies in the Textile wastewater
Dyes are natural compounds that make the worldmore beautiful through coloured substances. However, therelease of coloured wastewaters represents a seriousenvironmental problem and a public health concern. Colourremoval, especially from textile wastewaters, has been a bigchallenge over the last decades, and up to now there is no singleand economically attractive treatment that can effectivelydecolourise dyes. In the passed years, notable achievements weremade in the use of biotechnological applications to textilewastewaters not only for colour removal but also for thecomplete mineralization of dyes. Different microorganisms suchas aerobic and anaerobic bacteria, fungi and actinomycetes havebeen found to catalyse dye decolourisation. Moreover, promisingresults were obtained in accelerating dye decolourisation byadding mediating compounds and/or changing processconditions to high temperatures. This paper provides a criticalreview on the current technologies available for decolourisationof textile wastewaters and it suggests effective and economicallyattractive alternatives.
