The Bureau of Reclamation prepared this manual to provide an overview of microfiltration,
ultrafiltration, nanofiltration, reverse osmosis, and electrodialysis processes as they are used
for water treatment. position, the chemical processes, and the physical
processes involved with each membrane type are described pared. Because care and
maintenance of water treatment membranes are vital to their performance and life
expectancy, pretreatment, cleaning, and storage requirements are discussed in some detail.
Options for concentrate disposal, also a problematic feature of membrane processes, are
discussed. The culmination of this wealth of knowledge is an parison of water
treatment mercially available at this time. The tables cover physical
characteristics, performance data, and operational tolerances.
