Abstract
A membrane sampling device for use in a membrane filtration system having one or more pressure vessels for determining whether a filter membrane elements are performing properly or need replacement. The membrane sampling device is adapted to test operating conditions and to provide performance indicia in RO/UF systems without removal of filter membrane elements from the pressure vessel. A testing system is also provided that provides an improved means for testing multiple membrane sampling devices.
