Performance of a Biotrickling Treating Ammonia from Wastewater Treatment Plant

Article Preview

Abstract:

Biofiltration systems have become effective and inexpensive alternatives to conventional treatment systems. In this study, a functional bioreactor, e.g. the biotrickling filter was evaluated for its efficiencies in treating ammonia in the wastewater treatment plant at different loadings and its performance were studied. The experimental results showed that the influent ammonia can be efficiently removed in the biotrickling filter. The removal efficiency was above 90.7% when the inlet ammonia concentrations varied from 20 to 300 mg/m3and the flow rates were adjusted to from 0.61 to 1.06 m3/h.The results in microbial analyses indicated that the ammonia oxidizing bacteria and nitrite oxidizing bacteria were dominant in the biotrickling filter.
