BW 30-4040 membrane

These industrial membrane elements accompany a tough shell exterior and are recommended for RO systems with multiple-element housings containing three or more membranes, as they’re designed to face up to higher pressure drops.

Important Information:
Proper start-up of reverse osmosis water treatment systems is essential to organize the membranes for operating service and to stop membrane damage thanks to overfeeding or hydraulic shock. Following the right start-up sequence also helps make sure that system operating parameters conform to style specifications so that system water quality and productivity goals are often achieved. Before initiating system start-up procedures, membrane pretreatment, loading of the membrane elements, instrument calibration and other system checks should be completed. Please ask the appliance information literature entitled “Start-Up Sequence” for more information.

Operation Guidelines:
Avoid any abrupt pressure or cross-flow variations on the spiral elements during start-up, shutdown, cleaning, or other sequences to stop possible membrane damage. During start-up, a gradual change from a standstill to an operating state is suggested as follows: Feed pressure should be increased gradually over a 30-60 second time frame. Cross-flow velocity at a set operating point should be achieved gradually over 15-20 seconds. Permeate obtained from the first hour of operation should be discarded.

General Information:
Keep elements moist at the least times after initial wetting. If operating limits and guidelines given during this bulletin aren’t strictly followed, the limited warranty is going to be null and void. to stop biological growth during prolonged system shutdowns, it’s recommended that membrane elements be immersed in a preservative solution. The customer is fully liable for the consequences of incompatible chemicals and lubricants on elements. The maximum pressure drop across a whole pressure vessel (housing) is 50 psi (3.4 bar). Avoid static permeate-side backpressure at the least times.
