How to Reduce the Replacement Cycle of High-Flow Water Filter Cartridges

Jul. 24, 2023

In many water treatment systems, high-flow water filter cartridges serve not only for filtration but also play a crucial role in protecting the RO (Reverse Osmosis) membranes within the system.

Why is this considered a protective function? Taking a water desalination system as an example, the RO membranes in this system cannot be contaminated or clogged. Therefore, the liquid reaching this stage must go through primary filtration, during which there should be no significant pollutants or microorganisms. These are critical factors that can damage the RO membranes. Once the RO membranes are compromised, the entire desalination process will be disrupted, and the system may become inoperable.

The key reason why high-flow water filter cartridges are so important in water systems lies in their large filtration area, which ordinary water filter cartridges cannot match. The large diameter of these high-flow water filter cartridges not only improves filtration efficiency but also extends their lifespan. This results in a reduced frequency of replacements during operation, lowering investment costs for businesses and increasing overall profitability.

How to Reduce the Replacement Cycle of High-Flow Water Filter Cartridges

Product Features:

1. Combines surface and depth filtration, reducing the number of filter cartridges significantly compared to ordinary filters and significantly reducing the size of supporting housings.

2. The filter layer is made of efficient low-resistance materials, achieving a super-high filtration efficiency of over 99%, and extending the filter cartridge's lifespan.

3. Designed for easy handling, significantly reducing the time required for cartridge replacement, making the process simple and convenient.

4. Overall polypropylene design with thermal fusion welding, effectively preventing end cap detachment and secondary pollution.

5. Designed with sealed interfaces to reduce the risk of bypass and ensure reliable and effective filtration sealing.

6. Foldable design increases the filtration area, resulting in significantly lower pressure drop compared to ordinary filters.

7. Large diameter design increases pollutant capacity, prolonging the filter's lifespan and reducing production costs.

8. Equipped with a framework to enhance the filter cartridge's resistance to compression during use.


Frequent reasons for filter cartridge replacement:

1. Unstable raw water quality with frequent fluctuations, leading to excessive particulate matter entering the filter cartridge and shortening its service cycle.

2. Poor performance of pretreatment processes, incompatible or mismatched coagulants and antiscalants used in pretreatment, forming adhesive substances that adhere to the filter cartridge's surface, reducing the effective filtration area and resulting in frequent replacements.

3. Poor-quality filter cartridges with similar inner and outer pore diameters, where only the outer layer performs the interception. High-quality filter cartridges have progressively smaller filtration apertures from the outside in, with a finer inner layer with a filtration precision of 5±0.5µm and a larger pollutant capacity, ensuring the water quality remains qualified for a longer period of use.


Measures to extend the filter cartridge's service cycle:

1. The water source is generally fixed and cannot be easily changed.

2. Improve the performance of pretreatment processes by optimizing the dosage of coagulants and flocculants, selecting suitable antiscalants for the water source, adjusting each pretreatment device to achieve the best operating conditions, and strictly adhering to the operating procedures to ensure the pretreated water meets the required quality standards.

3. Choose high-quality filter cartridges with guaranteed performance, which can extend the filter cartridge's service cycle while ensuring that the water quality meets the required standards for the security filter outlet.
