PP, Polyester, Glass fiber membrane are commonly used for high flow filters.

(1) PP high flow performance filter is the standard type, used as-pre-filtration of RO system in SWRO, Power plant boiler feed water RO, industrial process water treatment.

PP polypropylene is a thermoplastic resin made by the polymerization of propylene. Bai polypropylene is a non-toxic, odorless, tasteless milky white highly crystalline polymer with a density of 0.90-0.91g/cm3, is one of the lightest varieties of all plastics.

It is particularly stable to water, and its water absorption rate is only 0.01%, the molecular weight is about 80,000 to 150,000. Good formability, good aging resistance, good chemical properties, almost no water absorption, and no reaction with most chemicals.

The fiber structure is loosened by acupuncture method to increase the impurity holding space. It belongs to the compound interception mode. Its internal honeycomb structure can effectively remove solid and soft particles.

That is, the larger particles are trapped on the surface of the fiber, and the fine the particles are captured in the deep layer of the filter material, and will not be damaged due to pressure increase during use, and has a high filtration efficiency.

In addition, the outer surface of the product is heat-treated by a high-temperature surface, that is, the application of instant sintering technology and calendaring treatment is effective Prevent the fiber from being dissipated by high-speed impact of the liquid during filtration.

And ensure no fiber detachment, avoiding the excessive clogging of filter holes caused by traditional rolling treatment and shortening the life of the filter bag.

At the same time, the pressure difference is small without affecting the flow rate; the accuracy is 0.4-200μ.

What is The Technical Data of High Flow Filter Cartridge?

How to Choose High Flow Filter Cartridge?

Filter Media

Any porous material that allows the fluid in the filter slurry to pass through and the solid particles contained in it is intercepted to achieve the purpose of solid-liquid separation is collectively called the filter medium.

There are a variety of filter materials on the market:

• Roll film that can be reprocessed;
• High-purity activated carbon particles;
• Filter bag material;
• Coalesce and separate materials;
• Sheet or paper filter material.

How About the Dirt Holding Capacity of a High Flow Filter?

Higher Dirt Holding Capacity

Dirt holding capacity is the total amount of dirt the high flow filter can catched in the filter when reach the replacement differential pressure. Advanced pleated technology provide bigger filtration area, high dirt holding capacity and long service life than others types filters.

How Long of the High Flow Filters Service Life?

Long service life of high flow filters

High flow filters have long service life than other standard size 2.7” pleated filter, because large diameter, high flow filter has bigger filtration area, long use life.

Different water quality, the filter service life is different. The dirtier the water, the shorter the service life of the high flow filter.

How to Define the Service Life of the High Flow Filter Cartridge?

1. Theoretical service life of the high flow filters

The high flow filter itself has a theoretical service life, which a value given by the cartridge filter manufacturer is based on the quality of the filter element and many years of filtration experience.

This value can be used as a reference value. In the case of normal operation of the filter equipment, if the use time of the filter element is close to the service life time limit given by the manufacturer.

You can check the filtering situation and consider whether the filter element needs to be replaced.

2. Cleanliness of the filtration machine

The cleanliness of the filtration machine must be taken into consideration. Generally speaking, the filter itself has various checkpoints.

These checkpoints may be loose or not cleaned during maintenance. Then some external substances may directly enter the filter equipment or the filter equipment itself.

Some impurities appearing in the wear, these impurities will directly affect the service life of the filter element to a certain extent.

Therefore, if the equipment has been used for a long time, but the time for maintenance has not yet arrived, and there are impurities on the equipment, then consider whether to replace the filter element in advance.

3. The condition of the filter liquid (water quality)

When determining the replacement time of the high flow filter, you also need to pay attention to the condition of the filter medium itself.

If the filter medium contains less impurities, then the wear of the filter element is relatively small. In this case, the service life of the filter element will be longer.

If there are relatively many impurities in the filter medium, it will cause serious wear and tear of the filter element in a short time, then the filter needs to check the cleanliness of the filter medium after filtration in advance to determine the filtration of the filter element Quality, and then determine whether to replace the filter element.

What is the Micron Rating for High Flow Filter Cartridge?

The filtration accuracy reflects the filtering ability of the filter medium to filter dirt particles. The evaluation of the filtration accuracy often has Absolute Rating and Nominal Rating.

1) Absolute Rating

Absolute filtration accuracy refers to the diameter of the largest hard spherical particle passing through the filter medium.

The maximum downstream particle diameter measured by multiple tests is the absolute filtration accuracy. Particles of this size are calculated by the filtration efficiency of 98%.

The equivalent capillary diameter of the first bubbling point measured by the bubble test is regarded as the absolute filtration accuracy.

2) Nominal Rating

The nominal filtration accuracy usually has the following two expressions.

1. The filtering accuracy given by the manufacturer is a generalized nominal filter accuracy. Such as the filtering accuracy in product samples or instructions.
2. In the multiple pass test, when the filter medium can filter out 95% of particles of a certain size and above, this size is the nominal filtration accuracy of the filter medium.

The high flow filter filtration rating is from 1 micron to 100 microns.

What the Applications of High Flow Filters

1) RO security filtration, seawater desalination pre-treatment

2) Filtration of power plant condensate

3) Filtration of raw materials, solvents and water in the biopharmaceutical industry

4) Filtration of bottled water, sugar liquid, edible oil, fruit juice, soft drink, milk

5) Paint, coating, petrochemical

6) Microelectronics, film, fiber, resin

Large-flow filter elements are widely used and can be customized according to specific operating conditions.

The flow rate of the large-flow filter element is several times that of the conventional filter element, which reduces the number of filter elements used and has a longer service life, which can save filtration costs and is deeply loved by customers.

How You to Calculate the Filtration Area of the High Flow Filter?

For 60″ high flow filters, the filtration area is 10㎡.

For 40″ high flow filter, the filtration area is 6.6㎡.

Surface area: total membrane used in one high flow filter. We also call filtration area. The filtration area is more bigger, the dirt holding capacity is more much higher.

Pleat number: total pleats in one high flow filter. The filter use advanced pleated technology.

According to the filter material ratio and thickness, the pleat number of the high flow filter of different precision is also different.

For the high flow filter of the same specification, the thinner the material layer, the more pleats, and the larger the filtration area.

We have imported filter materials, which are thinner than domestic filter materials and have good filtration performance, which are deeply loved by customers.

Pleat height: the height of each pleat. It’s design according to the filter structure. Different high flow filters have different pleat height.

Length: total length of the filter body with pleated material. According to customer needs, high flow filter of different lengths can be customized.

How To Install The High Flow Filters?

Installation steps of large flow filter:

1: When installing the high flow filter, the O-ring should be wetted in clean water or filtrate to reduce the friction when inserting. And it is required to insert it to the end to ensure that the O-ring plays a sealing role.

2: Press the pressure plate on the upper end cover of high flow filter, and lightly tighten the screws on the pressure plate to fix the pressure plate.

3: When the high flow filter filters liquid, you should first turn on the exhaust switch on the housing to empty the gas in the filter housing and fill the filter housing with liquid, otherwise it will affect the flow rate.

4: The fluid filter will produce a pressure drop due to resistance. In order to overcome the resistance, there must be sufficient working pressure. In order to prevent the filter element from being impacted by a large flow, the valve should be opened slowly.

High flow filter cleaning and sterilization:

1: On the production line, the high flow filter generally chooses backwashing: first turn off the original liquid and filtrate pipeline switches, rinse with bacteria-free water, input from the original outlet, and discharge from the inlet or the lower drain hole of the filter. Backwashing must be provided the pressure should not be too high, usually around 5 kg.

2: Remove the high flow filter and clean it in the cleaning solution, soak it first and then repeatedly clean it. Cleaning fluid is generally available:

A: Sodium hydroxide, 0.1N NaOH

B: 1-2% citric acid water solvent or 0.1N oxalic acid solvent, 0.1N hydrochloric acid solvent:

C: Enzyme solvents and other solvents. Generally, it is best to control the temperature at 30-40 degrees during cleaning.

Filtration Performance Requirements of High Flow Filter

1. Filtration efficiency: that is, the purification efficiency is high, and the purification efficiency is related to the structure of the filter material. Generally, the efficiency of non-woven felt filter material is high.
2. Air permeability: refers to the amount of air that the filter material passes through per unit area under a certain pressure difference. Resistance directly affects the air permeability. Large resistance increases energy consumption. The resistance of the filter material must be appropriate to ensure that the filter material has an appropriate air permeability.
3. Dust holding capacity: refers to the amount of dust stored per unit area of the filter material at the specified resistance, calculated in kg/㎡. The dust holding capacity is related to the porosity and air permeability of the filter material. The dust holding capacity is large, the cleaning cycle of the filter element is longer, and the service life of the filter element is correspondingly longer. Generally, the non-woven felt filter material has a larger capacity than the woven filter material.
4. The selection of the fiber of the filter material is very important. When it comes to the service life of the filter material, it is necessary to consider the temperature resistance, flame retardancy, chemical stability and the physical and mechanical properties of the fiber material from the use of wear resistance and bending resistance. , High strength requirements.
5. Economical type of filter material: cost performance is generally measured by the price and service life of the filter material.
