Abstract
In an apparatus for providing a continuous integrity test for suction driven filtering membrane assemblies a monitoring line diverts a portion of permeate to a monitoring device (e.g. a turbidimeter). Both ends of the monitoring line are connected to the permeate pipe upstream from the permeate pump and at points of relatively higher and lower pressures respectively, to cause fluid to flow through the monitoring line. The relatively higher and lower pressures may be caused by a source of head loss (e.g. a valve) in the permeate line. The source of head loss may be adjusted to provide a required flow through the monitoring device by a control communicating with a flow meter in the monitoring line. Membrane assemblies may be individually monitored although many of them may be connected to a common permeate pump (FIG. 2).
