Ensuring that the UF system is properly started is critical to preparing the membrane for operation and preventing potential membrane damage. Following the correct startup sequence is essential to maintaining system parameters within design specifications, helping to achieve water quality and productivity goals.
Before beginning the startup procedure, membrane preconditioning, membrane module installation, instrumentation calibration, and system checks must be completed per the guidelines outlined in the product technical manual.
To prevent membrane damage, sudden pressure changes during startup, shutdown, cleaning, or other sequences should be avoided. Before startup, flush the UF system thoroughly to eliminate any remaining shipping solution. In addition, purge any residual air from the system before commencing operation.
Start the unit manually, with the goal of achieving an initial permeate flow rate of 60% of the design capacity. Depending on the application, it may be necessary to discard the permeate obtained during initial operation. Refer to the product technical manual for detailed instructions.
General information
If operating limits and guidelines given in this bulletin are not strictly followed, the limited warranty (Form No. 795-00027) will be null and void.
To prevent biological growth during system shutdowns, it is recommended that preservative solution be injected into the membrane modules.
Regulatory note NSF/ANSI 61 certified drinking water modules require specific conditioning procedures prior to producing potable water. Please refer to the product technical manual flushing section for specific procedures. Drinking water modules may be subjected to additional regulatory restrictions in some countries. Please check local regulatory guidelines and application status before use and sale.
