Monitoring unit for monitoring the condition of a semi-permeable membrane

摘要: The invention concerns a monitoring unit [10] for the condition of semi-permeable membrane [24] in water purification system, and particularly spiral reverse osmosis system. comprises flow chamber [12] that includes an inlet permitting ingress feed fluid into [12], outlet [22] at least partial through-flow through such cross-flow conditions apply [12]. is partly supported further one [18] arranged communication with egress from after having passed [24]; inspection window [20] visual [24]. also extends to use evaluating various operating parameters system including or test cell.
