Carbon cycling and the availability of organic carbon for nutrient removal processes are in
most wastewater treatment systems restricted by the rate of hydrolysis of slowly …

Mathematical Modelling and Computer Simulation of Activated Sludge Systems–Second
Edition provides, from the process engineering perspective, a comprehensive and up-to …

Applications of activated sludge models (ASM) in simulating industrial biological wastewater
treatment plants (WWTPs) are still difficult due to refractory and complex components in …

Intermittent aeration of activated sludge plants (ASPs) is a potential strategy that may help
deliver reduced operational costs while providing an adequate effluent quality. This review …

Aeration is the most energy intensive unit operation in municipal wastewater treatment, and
fine‐pore diffusers have been widely used to minimize power consumption. Unfortunately …

This study investigates a post-denitrification process without the addition of an external
carbon source combined with an enhanced biological phosphorus removal (EBPR) in a …

In this study, the metabolism of glycogen storage and consumption in mixed cultures under
aerobic conditions is described. The experimental results are used to calibrate a metabolic …

The study aims to evaluate the role of a polymeric substrate (starch) on sludge settleability.
Despite being an important COD component of the wastewater, the relationship between …

Reduction of excess sludge in an oxic-settling-anoxic (OSA) activated sludge process might
be attributed to a “sludge fasting (insufficient food under an anoxic condition)/feasting …

A system which combined ASBR with pulsed SBR (PSBR) was introduced to enhance COD
and nitrogen removal from the real landfill leachate. ASBR was used to degrade the …
