Apparatus and method for the monitoring of membrane deposition

摘要

An in-line apparatus for monitoring membrane deposition is provided having an exterior body that defines an interior compartment for receiving a fluid stream. A coupon rack is positioned in the interior compartment and suspends at least one coupon holder. The coupon holder holds at least one membrane for collection of deposition present within a filtration system. The apparatus allows examination of membrane surface deposition without sacrificing a membrane element and also provides timely diagnostic information on a filtration system. The present invention also provides a method of monitoring membrane deposition as well as a filtration system incorporating an in-line apparatus for monitoring membrane deposition.
