Advantages of the DOW Ultrafiltration Modules:

* Excellent removal of colloids, particles, and bacteria, ensuring high-quality drinking water.

* Low chemical consumption, reducing operational costs and environmental impact.

* Ability to effectively treat challenging feed water, even with limited pretreatment, for a more efficient process.

* High chemical-tolerant PVDF material, allowing for aggressive chemical use when needed to tackle particularly difficult water qualities.

* Mechanically strong fibers ensure a long module lifespan, providing reliable performance over extended periods.

Important Information Regarding UF System Start-Up:

Proper start-up of a UF system is crucial for preparing the membranes for operational service and preventing any damage. Adhering to the correct start-up sequence is essential to ensure that the system's operating parameters align with the design specifications, allowing for the achievement of water quality and productivity goals. Prior to commencing the start-up procedures, it is vital to complete the membrane pretreatment, installation of membrane modules, instrument calibration, and conduct other system checks. For detailed instructions and guidelines, please refer to the product technical manual.

Operation Guidelines for UF System:

During start-up, shutdown, cleaning, or any other operational sequences, it is crucial to avoid any abrupt pressure variations to prevent potential membrane damage. Before commencing operation, ensure to flush the UF system thoroughly to remove any shipping solution residue. Additionally, remove any residual air from the system to prevent any operational issues.

Manually start the equipment and initially target a permeate flow rate of approximately 60% of the design flow rate. Depending on the specific application, it may be necessary to discard the permeate obtained during initial operations.

For detailed operational instructions, including recommended flow rates, cleaning procedures, and troubleshooting guidelines, please refer to the product technical manual. Adhering to these guidelines will ensure optimal performance and longevity of the UF system.
