"Over 80 percent of textile finishing mills discharge their wastewater to publicly owned treatment works. A variety of wastewater recycle technologies have been developed to allow these mills to reduce the volume of wastewater and amount of pollutants discharged. Only a few of these technologies have become widely applied in the textile finishing industry. Specific technical and economic factors affect the application of most of these technologies at a given mill; thus each application must be considered under its own mill-specific conditions. This report presents detailed information on textile wastewater recycle/reuse technologies. Included for each are a description of the technology, its environmental benefits, recycle system and treatment system schematics, design criteria, a discussion of technical factors that limit or enhance its application, capital and yearly cost, an examination of factors that affect its economic feasibility, lists of its current applications, and references for further information. The information in this report is based on a survey of the literature, discussions with technology vendors and researchers, and engineering studies conducted at six textile finishing mills. The six mill engineering reports appear in Volume 2 of the report." |
