Experiments were performed on a laboratory model of a hybrid bioreactor consisting of an aeration tank to which
support media were added to simulate both suspended and attached growth reactors, a secondary clarifier and a
recycling system. The system was operated for a period of two months, using synthetic wastewater for the
substrate medium. Support media were added to the reactor in stages of six nets each stage, so as to evaluate the
impact of the addition of the support media on the efficiency of treatment. Relevant parameters were measured
regularly. The study demonstrated the positive effects the system had on BOD5 removal and the settling
efficiency in the secondary clarifier
