Grates[edit]

Geotextiles/filter fabric[edit]

Laboratory research has demonstrated that the performance and clogging of maturing filter fabric can be predicted mathematically, based upon the media/filter material particle size distribution [1]. Elsewhere teh mechanisms behind the clogging have been studied and characterised using CT-scanning technology [2].

Filter media[edit]

Salty water has been shown to cause degradation of the filter media, and subsequent loss of the initial text and flow conditions [3]
