AWWA-64096 WSO: Membrane Technology DVD

Water operator training DVD describes the basics of microfiltration, ultrafiltration, nanofiltration and reverse osmosis technologies for water treatment.

Constructing and operating a membrane water treatment facility once was prohibitively expensive for all but specialized uses, but membrane treatment is now a viable option for many cities. 
This DVD provides an overview of all common pressure membrane processes: microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. It teaches operators basic membrane theory, selection based on type of contaminant to be removed (including desalination), process operation, equipment installation, and maintenance. 
The program also explains pretreatment for membrane treatment, membrane fouling, residuals disposal, and energy requirements. (15 minutes)
