"About 80% of textile finishing mills discharge their wastewater to publicly owned treatment works. Most of the wastewater receives little or no pretreatment before discharge. A variety of wastewater recycle/reuse technologies, allowing these mills to reduce the amount of wastewater and pollutants discharged, were described in an earlier (Phase I arid II) report. This two-volume (Phase III) report examines in detail one of these recycle technologies, dyebath reconstitution and reuse. This technology is considered promising for several reasons: significant environmental benefits, potential for widespread application, low capital cost, cost savings in textile dyeing, and economic attractiveness. Volume 1 gives results of a detailed investigation of dyebath reconstitution and reuse at a carpet mill. The results of bench-, pilot-, and full-scale testing are presented. Wastewater data documenting the pollutant reductions achieved through dyebath reuse are presented. The economic feasibility of implementing the technology full-scale is addressed. Volume 2 gives detailed procedures and methods for implementing dyebath reconstitution and reuse. It can be used as an operations manual for other mills wishing to investigate this technology." |
