Method of monitoring membrane separation processes

摘要

The invention provides a method of monitoring a reverse osmosis membrane separation process including a reverse osmosis membrane capable of separating a feed stream into at least a first stream and a second stream wherein the monitoring substantially consists of: providing at least one inert fluorescent tracer; introducing the inert fluorescent tracer into the feed stream; providing at least one fluorometer to detect the fluorescent signal of the inert fluorescent tracer in at least one of the feed stream, the first stream and the second stream; and using the at least one fluorometer to determine an amount of the inert fluorescent tracer in at least one of the feed stream, the first stream and the second stream.
