Removing nitrogen from wastewater with side stream

2016-2-1  Total nitrogen removal efficiencies in these years varied from 51% to 63% (average 58%). For SHARON in the side stream, efficiencies ranged from 52% to 60% over the years 2002–2004. This ranges in nitrogen removal efficiencies are reflected in the uncertainty in marine eutrophication potential.

Full-scale N removal from centrate using a sidestream

Immediately after the sidestream treatment system was placed into service, nitrogen in the mainstream facility was measured at concentrations significantly lower than typical and was sustained at historically low concentrations throughout the operation. This translated into a significant methanol cost savings of $1,500 per day (USD).

The nitrogen removal efficiency of the sidestream activated sludge process was less than 80%, whereas the phosphorus removal efficiency was generally above 90%. Despite of different removal efficiencies, nitrogen and phosphorus removal mechanisms may be attributed to a common assimilation process in the mainstream aerobic stage.
