Operational Guidelines

• Proper start-up of an ultrafiltration system is essential to prepare the membranes for operating service and to help prevent membrane damage.
• Avoid any abrupt pressure variations during start-up, shutdown, cleaning or other sequences to prevent possible membrane damage.
• Flush the ultrafiltration system to remove shipping solution prior to start-up.
• Remove residual air from the system prior to start-up.
• Target a filtrate flow of 60% of design during initial operations.
• Depending on the application, filtrate obtained from initial operations should be discarded.
• To prevent biological growth during extended system shutdowns, it is recommended that storage solution be injected into the membrane modules.
• NSF/ANSI 61 certified drinking water modules require specific conditioning procedures prior to producing potable water.
• Refer to the product technical manual for detailed start-up, flushing, and storage procedures.
