Developing and combining technologies for the treatment and recovery of dyehouse waste water sources

Objective



The Feasibility Study has shown that there is significant interest amongst textile processing companies in the EU for reliable cost-effective compact water recycle plant. In countries where water and sewerage are costed by processors on a volume rate of use basis, recycling can reduce overhead costs of the business by-a significant margin. For processors in other regions, there may be a lack of water resources leading to interrupted supply which is an important motivator. Any volume reduction should be accompanied by COD and colour reduction in order to effect environmental improvement. and possibly to avoid breach of consents for discharge. A combination of filtration and regenerable adsorbent acting as pretreatrment to reverse osrnosis is effective in achieving these requirements. Experience has shown that equipment must be tested under actual factory conditions and that trials must be of extended length due to the longer-term effects of effluent upon treatment systems. It is recommended to conduct trials of 12- 18 months' duration at factory sites using the combination of technologies listed above and to provide flexibility in the construction of the pilot plants to allow modifications to be made in the light of experience and developing best practice during the project. Specific action is recommended to investigate the issue of recycle water quality in respect of dyehouse performance in order to research optimum plant configuration.
