ABSTRACT:
A test probe for collecting test permeate samples from a multiple, reverse-osmosis membrane module, wherein the membrane module has a straight permeate-collection passageway and a plurality of individual, spaced-apart, permeate passageways which permit permeate, from each of a plurality of membranes, to flow into the permeate-collection passageway, and which probe comprises a first outer and a second inner tube concentrically positioned and spaced apart, whereby, on insertion of the test probe into the permeate-collection passageway, the test probe comprises a downstream permeate flow passageway and an upstream permeate flow passageway and a test permeate flow passageway, the test probe having a spacer element at the test end with a radial passageway, and resilient O-rings above and below the spacer element, and a coiled spring to bias the O-rings between an unbiased, nonsealing position and a biased, sealing position, whereby the O-rings extend radially outwardly, to form a seal above and below a test permeate passageway, and permit flow of the permeate from the individual passageways into the test permeate flow passageway, while not disrupting the flow of the upstream and downstream permeate.
