investigation of the efficiency of sequencing batch reactor (sbr) in cefixime antibiotic removal from aqueous solutions

We investigated the removal of cefixime (cef) from synthetic wastewater using sequencing batch reactor (sbr) in the present study# the elimination of antibiotics using activated sludge process before and after biodegradation was measured by the uv spectroscopic method# antibiotics wastewater contains organic and inorganic matters which are toxic to the ecosystem and difficult biodegradable# the initial concentration of chemical oxygen demand (cod) as optimum parameter for removal of antibiotics using sbr was systematically studied# an aerobic bioreactor is used for antibiotic wastewater treatment# in the biological treatment, mlss and aeration time have positively related to process efficiency# the experimental results showed that after biological treatment, in various loading conditions, removal rate of cod of synthetic wastewater were 65#2%, 71#42% and 68#6%, respectively#
