- Abstract
The environmental issues associated with residual colour in textile effluents have posed a major challenge to environmental scientists as well as the textile colouration processors. The requirements to remove colour from textile effluent on site prior to discharge to sewer have been progressively tightened due to increased public complaints about coloured watercourses. Dyes are highly dispersible aesthetic pollutants and are difficult to treat, as most dyes are highly stable molecules made to resist degradation by light, chemical, biological and other treatment or exposure. There has been a lot of research going in the past few decades to develop efficient and cost effective technologies to remove colour from textile effluent. This paper presents a critical review of the current literature available on various textile wastewater decolourisation techniques being applied and researched to remove colour from textile wastewater.
