Abstract: The most inexpensive method for treating synthetic organic chemical (SOC) contaminated wastewaters was studied. Air stripping, liquid-phase adsorption, fixed-film biological oxidation, and biodegradation within a carbon adsorption column were four aqueous methodology evaluated. At the same time, gas-phase adsorption on-site regeneration, gas-phase adsorption off-site regeneration, thermal incineration, and catalytic oxidation were four off-gas treatment assessed. The most cost-efficient design was considered for treatment of typically contaminated wastewaters such as groundwaters, drinking waters and industrial wastes. Mathematical models together with cost models using FORTRAN computer programs were applied in the evaluation of each treatment process.
