Abstract:

The influence of plant parameters on effluent organic nitrogen was investigated for two advanced wastewater treatment plants in the Chesapeake Bay region. The study investigated the influence of process start-up, reactor configuration, solids retention time (SRT), temperature, chemical dosing and digester recycles. The study concluded that activated sludge process treatment efficiency, as defined by removal of degradable constituents, may have a dominant role in maintaining low concentrations of effluent organic nitrogen. Factors influencing treatment efficiency include SRT, temperature, reactor hydraulics (reactors-in parallel versus reactors-in-series) and plant perturbations. These same factors all impact effluent organic nitrogen. For example, longer SRT, reactors-in-series and higher temperatures all produce lower effluent organic nitrogen and are known to produce higher treatment efficiency. Plant perturbations also impacts treatment efficiency by increasing residual organic nitrogen concentration. It is still unclear what fraction of the organic nitrogen material is degradable within the activated sludge process and is a matter for further study.
