  • Methodology for sampling drinking water discolouration loose deposits at low velocities

    The occurrence of discoloured water at the tap is one of the most frequent reasons for customers to complain. Water discolouration arises from the re-suspension of loose deposits (LD) that accumulate in drinking water pipes, due to velocity increase. Because of its typical brownish/reddish colour, discoloured water is traditionally perceived as a consequence of cast-iron pipe corrosion, even in ...

  • The effect of heavy metals on the activated sludge process and its microbial community analysis using 16S ribosomal DNA

    The effect of heavy metal shock loading on biological treatment systems was studied by traditional methods and molecular biological techniques. Two kinds of SBR (sequence batch reactor) operation units, unacclimated and acclimated activated sludge systems, were studied. The addition of special nutrients and powdered activated carbon (PAC) to stimulate heavy metal uptake and recovery were studied. ...

  • Preliminary stabilisation of stormwater biofilters and loss of filter material

    Stabilisation affects performance of stormwater biofilters operating under intermittent wetting and drying, mainly due to wash-off of filter material. Understanding the dynamics of solids wash-off is crucial in designing stormwater biofilters. The current study analysed the dynamics of solids wash-off in stormwater biofilters and quantified the loss of solids from the filter. Four Perspex™ ...
