To ensure proper start up of RO water treatment systems is essential to prepare the membranes for operating service and to prevent membrane damage due to overfeeding or hydraulic shock. Following the proper start up procedure (available with water treatment system guide book) also helps ensure that system operating parameters conform to design specifications so that system water quality and productivity goals can be achieved. Before initiating system start up procedures, membrane Pre-treatment, loading of the membrane elements, instrument calibration and other system checks should be completed. Operation Guidelines: It is CRITICAL to avoid any abrupt pressure or cross-flow variations on the RO membrane elements during start-up, shutdown, cleaning, or other sequences to prevent possible membrane damage. During start up, a gradual change from a standstill to an operating state is recommended as follows: Feed pressure should be increased gradually over a 30-90 second time frame. Cross-flow velocity at set operating point should be achieved gradually over 15-30 seconds. Permeate obtained from the first hour of operation should be discarded. Important Information: Keep RO membrane elements moist at all times after initial wetting. If operating limits and guidelines given in this specification are not strictly followed, the limited warranty with the supplier will be null and void. To prevent biological growth during prolonged system shutdowns, it is recommended that RO membrane elements be immersed in a storage solution. The customer is fully responsible for the effects of incompatible chemicals and lubricants on elements. The maximum pressure drop across an entire pressure vessel (housing) is 50 psi (3.4 bar). Avoid static permeate-side back pressure at all times
