Effects of copper shock load on activated sludge process were investigated. Oxygen uptake rate measurements proved to be a rapid and reliable tool to detect inhibition within one hour from the shock load. Four types of kinetic models describing metal inhibition were investigated and employed to fit experimental data. Kinetic parameters were determined by non-linear least square correlations. Both non-competitive and competitive models resulted to provide the most accurate description of copper inhibition.

Abstract
Effects of copper shock load on activated sludge process were investigated. Oxygen uptake rate measurements proved to be a rapid and reliable tool to detect inhibition within one hour from the shock load. Four types of kinetic models describing metal inhibition were investigated and employed to fit experimental data. Kinetic parameters were determined by non-linear least square correlations. Both non-competitive and competitive models resulted to provide the most accurate description of copper inhibition.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
