Rapid Determination of Bacterial Assemblage Structure: Implications to Process Optimisation in Wastewater Treatment

  • T. D. Waite

A rapid method of determining the structure of aggregated particles using small angle light scattering is applied here to assemblages of bacteria from wastewater systems. While a number of problems including those caused by polydispersity and multiple scattering must be addressed, structure information can be conveniently obtained by judicious analysis of the light scattering data. Strong dependencies are shown to exist between the structure information as determined by small angle light scattering and the efficiency of biosolids dewatering by pressure filtration and centrifugal methods. The rapidity of determination of structural information and the strong dependencies of the effectiveness of a number of wastewater treatment processes on aggregate structure suggests that this method may be particularly useful as an on-line control tool.
