The need to understand the relationships found in membrane unit processes for water treatment increases with the continuing demand for these separation systems. Defining the terms common to microfiltration, ultrafiltration, nanofiltration and reverse osmosis processes assist the manufacturer, consultant and end-user in eliminating inter-process terminology confusion. This standard expands the definitions found in Terminology D1129.

1. Scope

1.1 This terminology covers the use of microfiltration, ultrafiltration, nanofiltration and reverse osmosis for membrane separation processes.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
