Activated sludge lagoon effluent

This work demonstrated the potential of US for mitigating membrane fouling. However, the integration of the US transducers within the membrane system will be a major challenge for the application of US in membrane cleaning. It is more appropriate that US is used as pre-treatment to the membrane system, the transducers can be placed prior to the coagulant feed line. Further work on the determination of the detailed mechanisms associated with enhancing coagulation would enable optimisation of the system with regard to process, cost and energy efficiency.

The primary objectives of this study were to: Investigate the fouling potential, and characterise the organic components of the membrane foulant layers, of clarified activated sludge and lagoon effluent obtained from the WTP; Investigate the fouling propensities of EOM and AOM derived from a blue-green algal culture as it passed through the growth cycle, ie., for which the cells had not been subject to physical disruption; Determine any difference in the fouling propensity of EOM and AOM and relate it to organic composition.
