To date, little research has been done on the effects that recycle of waste filter backwash has on treated water quality. To add to the limited data available on effects of recycle, the authors documented and evaluated the waste filter backwash water recycle practices at six full-scale surface water treatment plants in Connecticut. Because each treatment plant operates differently, understanding the effects of recycle requires detailed and site-specific information. The results of this study can help utilities improve operation and monitoring to control potential recycle effects and gather appropriate information for understanding recycle practices. Includes 20 references, tables, figures.
