This work is based on an ongoing AWWARF research project on integrity testing of
low pressure membrane processes. The project includes an evaluation of existing and improved
membrane integrity monitoring methods through testing at full-scale plants representing different
membrane systems. The project approach focuses on surveying, full-scale testing, and validation
of several existing and improved or newly developed integrity monitoring methods. This paper
focuses on describing the membrane integrity monitoring methods, testing methodology, and the
role integrity monitoring can serve in the granting of microbial removal credits.
Membrane integrity method classification into direct and indirect methods is described.
Preliminary results from an international survey on the usage of different integrity methods are
presented.
The link between detection ability of membrane integrity methods and removal credits is
described. The well observed and known removal ability of MF/UF membranes, coupled with
the relatively lower removal credits that are currently granted, indicate that the credits granted
can be potentially increased or better determined if the integrity monitoring of membrane
systems can be better understood, implemented, or improved.
Includes 7 references, tables, figures.
