Fiber glass production involves the use of an expensive phenolic resin. A 28 month study was conducted to determine the feasibility of reclaiming waters which had been used for washing resins off of conveyor lines to prevent fouling. The system developed reduces water consumption by utilizing an 8 gpm, 1000 psi spray cleaner. After the conveyors are washed, the water flows through two stages of screening, or primary filtration, and a secondary diatomite filtration unit. Since most of the solids are large, the diatomite filters accomplish the removal of only .6% of the total solids load, with the major removals taking place at the pre-screening equipment. The water re-use system will use the same water 4.5 times before it is completely evaporated, requiring 1 lb of diatomite/500 gallons of water filtered. The system provides water at a net cost of $.37/1000 gallons as compared to $.75/1000 gallons for city water. Substantial operational savings have been realized through conservation of the expensive phenolic binder. Waste phenolic discharges have dropped 80%, suspended solids have decreased 85%, and dissolved solids have decreased by 50%. In this instance, therefore, waste discharge control has both protected the environment and profited the industry. (WRS abstract)
