Thomas, S. AND D. Walch. DEMONSTRATION OF A CLOSED LOOP REUSE SYSTEM IN A FIBERGLAS TEXTILE PLANT. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/2-80/040 (NTIS PB80197064), 1980.
Description:
The report describes work done toward providing a totally recycled water system for Owens-Corning's textile fiber manufacturing plant at Anderson, SC. (The work was based on pre-1968 pilot plant work by Owens-Corning that resulted in development of totally recycled industrial wastewater systems for all of their insulation manufacturing plants). Water quality requirements for the Anderson plant were considerably more stringent than for insulation manufacturing. Test and engineering design work started in 1973. Design work was completed in March 1977 and actual field work was started. All sanitary wastes from the plant were segregated for separate treatment. Much modification to the existing treatment was required to improve the quality of primary and secondary effluent for tertiary treatment. In the final process, biologically treated effluent is sand-filtered, followed by activated carbon adsorption and disinfection with chlorine. Major items of equipment added were a commercial upflow pressure sand filter and three upflow activated carbon columns with backwash capabilities. The quality of treated effluent is completely satisfactory for all plant operating requirements. Total recycle of treated effluent was realized in mid-1978 and has continued since then. Complete closed-loop operation had not yet been achieved. Discharge to Betsy Creek has been greatly reduced.
