Abstract
The development and successful demonstration of laboratory and pilot-scale fluoride treatment techniques for selected aerospace and metalworking industry chemical processing solutions and rinse waters are described. Included are laboratory-scale, lime treatment parameters for chemical processing solutions such as temperature, retention time, pH, slurry concentration and fluoride influent and effluent levels, and ion-exchange treatment to reduce the fluoride concentration of rinse waters to levels less than three parts per million. Pilot studies of centrifugal techniques to separate lime-precipitated bridges from titanium chemical milling, titanium descaling and aluminum deoxidizing solutions show that lime precipitation can give final effluents having fluoride concentrations less than three parts per million. Aluminum conversion coating solutions, however, require secondary treatment with aluminum sulfate to give final effluents having fluoride concentrations less than three parts per million. Chemical and mechanical property tests show that it is potentially feasible to use calcium fluoride sludge as a strength-maintaining additive for concrete. The reuse of treated rinse waters, the economics of precipitation, and production plans for chemical processing solutions and rinse waters are also presented.
