The textile industry consumes large amounts of clean water in various production lines, especially in textile processes in dye-house. Sustainable water management in textile dye-houses may be achieved by implementing a segregated wastewater treatment and reuse concept with which all wastewater streams with high water reuse potential and high economic feasibility are identified.
This thesis aimed at identifying reusable wastewater streams and investigating their reuse potential in cotton processing textile dye-houses. Thus cooperation with such a dye-house, located in Germany, was established for this thesis. This dye-house uses discontinuous batch operations for bleaching (hydrogen peroxide bleaching), dyeing (mainly reactive dyeing) and corresponding washing/rinsing steps. Accordingly, it produces bleaching wastewater (BW), bleaching washing wastewater (BWW), dyeing wastewater (DW) and dye-wash wastewater (DWW). These wastewater streams were investigated for their reuse potential by applying advanced membrane filtration processes.
