Nitrogen removal communities performing wastewater treatment consist of ammonia oxidisers, nitrite denitrifiers, and anammox bacteria, the proportion activity particular microbial groups depend not only on physiochemical parameters bioreactor, but also composition inoculum. Nitrifiers denitrifiers usually dominate in conventional systems due to fact that nitrification denitrification are most commonly used nitrogen processes. However, from economical point view case with high concentrations, anammox-based technologies desirable for their treatment. The disadvantage such is slow bacteria growth, which extends an effective technological start-up. Thus, this study, a fast start-up process supported anammox-rich inoculum was performed sequencing batch reactor (SBR). Using inoculation SBR laboratory system, can be fastened 85 days 84.5% efficacy. spatial distribution analysed fluorescent situ hybridisation revealed nitrifiers located side by flocs relative number oxidisers decreased after experiment.
