Abstract:
Given that the most polluting industries in the country there. A suitable treatment system for degradation of these compounds is necessary unless unexpected effect on environment will occur.Moving Bed Biofilm Reactor (MBBR) was developed to adopt the best features of the activated sludge process as well as those of the biofilter processes. MBBR has biomass growth on carriers that move freely in the water volume of the reactor. High surface area of carriers make a good condition for biomass attached growth. This system has had good operation in the urban and some industrial wastewaters.In this study, four reactor volume of approximately 16 litr and 6, respectively, in the aerobic, anoxic Bardenpho process to filter pollutants and nutrients has been used. The reactors were filled with Kaldnes as biofilm carrier (filling ratio of 30٪ and 50٪) The removal efficiencies were investigated at different hydraulic retention time (HRT) of 4, 8, 14 and 20hours and the ammonia concentration in 100, 180 and 260 mg / l , and ammonia and nitrateremoval rates measured
