6 benefits of PP pleated filter cartridge in industry applications

Are you in need of a high-performance, cost-effective filtering media for industrial filtration processes? PP pleated filter (pleated filter) is also one of the informed decisions to make. This filter component is produced with ultrafine polypropylene fiber membrane and nonwoven or mesh supporting layer, pleated and combined by hot melt welding technology, no glue, eliminate risk of secondary pollution root and branch.

Its special shape and material properties allow it to have excellent performance in various industries. Then, why can PP pleated filters be a promising solution to enhance your industrial filtration productivity, secure product quality and cost-competitive operation? 

1. Excellent filtration efficiency of PP pleated filter cartridge

Increase of effective filtering area:

By pleating the filter medium, the effective filtering area per volume can be much increased and that part of the volume can be used very effectively. Under the same size, the filtering area of traditional straight tube filter element is only several times or even ten times of the new design with a corrugated shape.

Deep filtration and sieving effect:

When a contaminated fluid flows through, those particles whose sizes are bigger than the pores of the filter membrane are blocked by the surface (sieving effect), meanwhile smaller particles will also be captured inside the fibers because of inertial impaction, diffusion and adsorption when them pass through tortuous membrane channels and get deep and fine filtered. It has a wide filtration accuracy from 0.1 micron to 60micron and is capable of removing small particles, bacteria and even colloidal dirt with a filtration efficiency of 99.8%.Such effective filtration results in cleaner filtrate and thus directly guarantees the quality and consistency of the end products.

2. Chemical compatibility ensure the safety of processes

The polypropylene material itself has good chemical stability, which directly makes the PP pleat filter cartridge have a wide range of chemical compatibility.

This product is resistant to most acids, alkalis, salt solutions, and various organic solvents, and has good resistance to commonly used chemical reagents such as sulfuric acid, hydrochloric acid, and sodium hydroxide. This is because the same filter element can be used to filter materials that have different chemical properties, avoiding the inconvenience caused by the frequent replacement of the model of filter elements due to the change of materials.

More importantly, the all PP material construction and hot melt welding process (no adhesive) makes sure that the filter media itself is not unnecessarily chemically reacted with the fluid while filtering nor will it leach components during the process, basically eliminating the danger of secondary contamination. It finds many uses in areas requiring ultra-high purity including *pharmaceutical, food and beverage and fine chemicals etc.

3. Outstanding pollutant carrying capacity and service life

Th long service life of the PP pleated filter cartridge is attributed to its excellent dirt holding capacity. The pleated design of filter not only expands the filter area, but also creates a large space to store the pollutants captured. This implies that the filter can trap more pollutants while the pressure drop slowly builds up, which greatly prolongs its replacement interval. The following table summarizes the differences in several properties of PP pleated filter and regular PP cotton filter:

The elongation of the replacement interval can bring about the reduction of not only the purchase cost of the filter element but also the replacement cost of the downtime, which is significant for stable operation in continuous industrial production.

4. Low voltage drop design reduces system energy consumption

The low pressure drop feature of PP pleated filter cartridge is another significance advantage. A low pressure drop indicates that the fluid has experienced less resistance while flowing through the filter media.

• Energy consumption reduction: Filtration system can maintain the flow associated with required flow without above needed initial pressure, thus directly reducing energy cost for pumping the fluid, as well as the energy cost for filtration.
• Enhancing the efficiency of the processing: Based on the same working pressure, higher processing flow may be obtained with the low flow resistance, thus the efficiency of whole filtration system can be enhanced.
  This feature can generate significant operating cost savings in applications involving large volume liquid filtration, such as in food and beverage, oilfield water injection and others.

5. Easy installation and maintenance process

• PP pleated filter design is fully user-friendly: Standardisation and Compatibility The filter cartridge has been standardised in terms of dimension (e.g. length 5“–40“, outside diameter 69mm, etc.) and interface (e.g. 215, 222, M30, etc.) to fit the majority of the standard filter housings, allowing the installation and replacement that is easy and swift.
• Easy maintenance: The replacement operation is simple when the replacement pressure difference is reached (Normally we recommend 1.5-2.0 bar). Some models of filter cartridges can be sterilized in-line with steam at 121 ℃ and reused limited times, with further reduction of long-term operation cost.
  
• Labor saving: Its high flow design slashing the number of filters needed to achieve the same processing capacity, means less replacement and maintenance work load. The installation and maintenance are so simple that it significantly decrease operators' workload and dependence on professional skills, and decrease the system downtime for maintenances.

6. Low cost and efficiency improvement

While the unit cost of the PP pleated filter may be higher than some of the traditional filters, its cost-efficiency is unparalleled when the whole lifecycle cost is considered.

• Extended replacement cycle: High dirt holding capacity that leads to longer service life results in less filter element consumption per time unit.
  
• Energy saving: characteristic of low voltage drop leads to low energy consumption for long term system operation.
  System efficiency: The high separation efficiency and excellent reliability of continuously stable main process reduce downtime due to separation-related problems.
  
  

Conclusion

To sum up, PP pleated filter cartridge is widely recognized as the best value for many industrial filtration applications because of its high precision and efficiency of filtration, wide chemical compatibility, good pollutant holding capacity, long service life, low pressure drop and energy saving, easy installation and maintenance, and excellent full life cycle economy.
From electronics with its ultra pure water preparation demanding extremely high purity to pharmaceutical and chemical processing of complex chemicals to food and beverage where water is used in massive quantities, it delivers dependable and productive solutions.
