Abstract

The pilot scale experiment was performed to investigate phosphorus and nitrogen removal from sewage by intermittently activated sludge process combined with the electrochemical interaction (Localized Corrosion) of aluminum and silver. The average T-N removal rate for HRT of 24hr was 57.4%. It was possible to remove P in sewage to under 1 mg/L with a short HRT of 12 hr using Al and Ag plate but often required additional A1 plate supplement during the operation.
