Respirometric analysis of activated sludge models from palm oil mill effluent

Activatedsludgemodels (ASMs) have been widely used as a basis for further model development in wastewater treatment processes. Values for parameters to be used are vital for the accuracy of the modeling approach. A continuous stirred tank reactor (CSTR), as open respirometer with continuous flow for...

It was found the mass transfer coefficient KLa is 0.3 h-1 during lag and start feed phase and 0.01 h-1 during stop feed phase, while the heterotrophic yield coefficient YH is 0.44.
