Proper start-up of reverse osmosis 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 sequence also helps ensure that system operating parameters confonn to design specifications so that system water quality and productivity goals can be achieved.
Before initiating system start-up procedures, membrane pretreatment, loading of the membrane elements, instrument calibration and other system checks should be completed.
Please refer to the application infonnation literature entitled "Start-Up Sequence" (Fonn No. 609- 02077) for more informâtion.
Avoid any abrupt pressure or cross-flow variations on the spiral elements during start-up, shutdown, .cleaning or other sequences to prevent possible membrane damage. During start-up, a graduai change from a standstill to operating state is recommended as follows:
These membranes may be subJect to drinking water application restrictions in some countries: please check the application status before use and sale.
