Nitrite Oxidizing Bacteria

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.

The performance of the primary anaerobic pond at the Alsamra Wastewater Treatment Plant in Jordan was monitored over 48 months. Overall averages for the removal efficiencies of BOD5, COD and suspended solids were 53%, 53% and 74%, respectively. An improvement in removal efficiency with increase in pond water temperature was demonstrated. A model, which takes into account the variability of raw wastewater at different locations, has been developed to describe the performance of a primary anaerobic pond in terms of a settleability ratio for the raw wastewater. The model has been verified by illustrating the high correlation between actual and predicted pond performance.
