dc.description.abstract |
The literature on chemical cleaning of polymeric hollow fibre ultrafiltration
and microfiltration membranes used in the filtration of water for municipal
water supply is reviewed. The review considers the chemical cleaning mechanism,
and the perceived link between this and membrane fouling by natural organic
matter (NOM)—the principal foulant in municipal potable water applications.
Existing chemical cleaning agents used for this duty are considered individually
and their cleaning action described, along with the most commonly applied
cleaning protocols (i.e. the cleaning conditions, cleaning sequence and method
of cleaning agent application). It is concluded that chemical cleaning is poorly
understood and not extensively investigated, in marked contrast to the much more
widely studied area of membrane fouling generally, for which there are thousands
of published studies. Studies of chemical cleaning specifically have instead
been generally limited either to qualitative measurements, such as the use of
surface or other analytical tools to characterise membrane foulants and record
their removal, or incidental permeability recovery recorded from cleaning events
during pilot or full-scale trials. It is proposed that a chemical cleaning index
is needed, analogous to the recently proposed general membrane fouling index,
based on empirical data to inform cleaning protocols for specific duties and
