Abstract
An Advanced Water Recycling Demonstration Plant (AWRDP) was commissioned and constructed
by the Queensland State Government in Australia. The AWRDP was used to study the effectiveness
of a variety treatment processes in the upgrading of municipal wastewater for water recycling
applications. The AWRDP consists of eight modules, each housing an individual specific treatment
process. These processes are flocculation, filtration, dissolved air flotation, ozonation, biological
activated carbon adsorption, microfiltration, reverse osmosis and ultraviolet disinfection. The
individual performances of the treatment processes were determined, as well as their
interdependence in series. A range of chemical water quality parameters were investigated. The
study provides a broad process comparison on the basis of an important catalogue of these key
parameters. This will be valuable in the selection and optimisation of treatment processes trains in
full-scale water recycling applications.
