     the reduction and degradation of total organic carbon (toc) and bacteria from a secondary effluent of synthetic slaughterhouse wastewater using vacuum-ultraviolet (vuv) and ultraviolet-c (uv-c) processes and their combination (uv-c/vuv and vuv/uv-c) were investigated. the toc removal rates under continuous mode operation ranged from 5.5 to 6.2%. in addition, the treatment with the uv-c/h2o2 and vuv/h2o2 processes under continuous mode operation doubled the toc removal rates 10.8 and 12.2%, respectively. the optimum molar ratio of h2o2/toc was found to be 2.5 and 1.5 for the uv-c and vuv processes, respectively. it was observed that all photochemical processes were able to totally inactivate different strains of bacteria with concentrations up to 105 cfu/ml within 27.6 s. finally, a kinetic model was developed to simulate the toc degradation from a secondary effluent of synthetic slaughterhouse wastewater.
