| Abstract |
The use of solvent extraction and ozonation to treat various industrial wastewaters was studied. Most were light chlorinated hydrocarbon, solvent wastes and were principally extracted with a high molecular weight paraffin petroleum fraction. Distribution data on related pure chlorinated compounds were also obtained. The economics of solvent extraction versus steam stripping was examined. Though chlorinated solvents can be effectively removed by extraction, stripping appears to be more economical. A toluene diamine wastewater was found treatable with benzene. In all these wastes there are unextractable fractions. Attempts were made to treat glycol, toluene diamine and light chlorinated hydrocarbon wastewaters with ozone, but results were not satisfactory. |
