Classification of Micron Cartridge Filter

There are many types of filter cartridge filter water for liquid filtration, which can basically be divided into two types: surface filtration type and depth filtration type.

①. Surface filter type 5 micron filter

The surface filtration type 5 micron filter captures pollutants on the surface of the 5 micron filter.

Once the surface of the 5 micron filter is blocked by the pollutants, it cannot be used continuously; micron rating for water filters so the surface filtration type 5 micron filter has a short service life.

Although the surface 5 micron filter melt blown filter is often considered to be able to be reused after backwashing with a mixture micron water filter liquid and compressed air, melt blown filter this method does not wash the filter cartridge clean.

When a certain part of the 5 micron filter is flushed and unblocked by the flushing fluid, this partial channel on the filter cartridge becomes the channel with the least resistance of the 5 micron filter.

The particle water filter and then all the flushing fluid is Will flow through these channels, but other parts will be more densely plugged, particle water filter the pores will become smaller.

If you want to completely rinse the filter cartridge, pure filter replacement the best way is to use ultrasonic cleaning, using pure water as the cleaning liquid, but the cost of ultrasonic cleaning is higher;

And replace sediment filter melt blown filter chemical dissolution method can also be used, for example, when the pollutants are acid-soluble, use dilute acid to clean.

But this melt-blown filter method may cause corrosion and enlargement of the pore size of the 5-micron filter, so the 5-micron filter cleaned by this method needs to be rinsed with pure water and can be used after passing the inspection.

The melt-blown filter Among the 5-micron filter for electroplating solution filtration, the earlier sintered polyvinyl chloride filter rods, melt blown filter the currently used polypropylene filter melt-blown 5 micron filter, replace water filter cartridge polypropylene filter PP filter paper, pure wood pulp filter paper, etc., are all surface filtration filter cartridge.

②. Deep 5 micron replace the water filter cartridge

The cleaning of the 5 micron filter is very troublesome, and increasing the dirt holding capacity of the 5 micron filter and prolonging the use time can reduce the frequency of cleaning the melt blown filter 5 micron filter.

The deep filtration type filter cartridge can do this. During the use of the deep filtration 5 micron filter, the pollutants are trapped in layers according to the particle size inside melt blown filter the 5 micron filter.

So melt blown filter the 5 micron replace water filter cartridge has a high load capacity of filter residue, a long service life, and can maintain the nominal filtration accuracy of the filter cartridge for a long time.

There are many materials used to make the structure of the 5 micron replace water filter cartridge, so melt blown filter this 5 micron replace water filter cartridge can almost be applied to the filtration of various liquids and gases.

The electroplating solution filter mainly uses a wire wound 5 micron replace water filter cartridge made of polypropylene filter, melt blown filter which is often called a cotton core.

Its advantages are: a smaller pressure difference can obtain a larger flow rate, 10 inch water filter cartridge melts blown filter high filtration accuracy, replacement cartridge a long service life.

And the accuracy stainless water filter the 5 micron water filter cartridge can string filter maintained string wound filter a long time during the filtration process.

How Does A String Wound Cartridge Filter Work?

The wire wound replace water filter cartridge is woven to form a gradient density,

The core is tighter and the outside is lighter. This means that larger sediments are filtered out at the beginning, quick change water filter and as the liquid passes through the medium, finer particles are gradually filtered out in each layer. Replacement filter element also filters from the inside to the outside. The winding method and controlled thickness of the filter cartridge can increase the dust holding capacity and extend the service life and efficiency of the filter.

The material of the wire-wound filter cartridge tightness of the wire during winding determines the accuracy of the wire-wound filter cartridge. Usually we can control the machine to ensure that the inside is tight and the outside is loose when winding, purifier cartridge so as to ensure that the filter cartridge can intercept more impurities when it is in use.

The Advantage of String Wound Water Filter

The string wound cartridge filter is widely used across industries and for various types of liquid filtration requirements, because of its filtration capabilities, high dirt holding capacity, and ability to keep form and last longer.

If manufactured to good quality, pp wound cartridge filter these types of filters do not collapse under pressure differentials. Additionally, most of the filter housings use ‘ knife-edge sealing’ to inset and seal the filter cartridges inside the housing.

While other cartridges may be susceptible to poor edge sealing resulting in by-pass problems, pp water filter cartridge good quality string wound cartridges hold their shape and are sturdy micron water filter.

Another feature of the wire wound filter cartridge is that it can pass a larger flow. Each wire wound filter cartridge of filtration accuracy has a fixed number of channels D.

After the filtration accuracy is determined, the number of channels L increases or decreases according to the length of the filter cartridge.

The formula for the total number of channels is: pp water filter total number of channels = D×L×2.

Take a filter cartridge with a length of 250 mm as an example, its filtration accuracy is 20 μm, the number of channels on its diameter is 15, and the number of channels along the length of the filter cartridge is 51, the total number of channels for the filter cartridge is 15×51× 2 = 1530, that is, there are 1530 independent channels on the filter cartridge.

If the filtration flow rate is 0.5m³/h (take clean water as an example), that is, 8.3 L/min, the liquid is dispersed into 1530 independent channels for filtration, and the flow rate in each channel has actually dropped to 5.4 mL/min.

If the filtering precision is 3 μm, the number of channels is 27, and the number of channels is 91, the total number micron rating for water filters channels on the filter cartridge is 27 × 91 × 2 = 4 914 (pieces).

Therefore, for the 3 μm precision filter cartridge, although the filter medium (i.e., fiber fluff) has become denser, the number of filter channels has increased to 4,914, and the flow rate in the channel is only 1.7 mL/min. The flow rate at this time can be called “Siphon Flow”.

It can be seen that the wire-wound filter cartridge can pass through the filter cartridge with a large flow rate during filtration, filter stainless steel pp string wound filter cartridge but installation of water filtration system structure of dispersing the flow rate allows the filter cartridge to maintain its excellent filtration performance under a small pressure difference.

This structure of the filter cartridge is also beneficial Filter out colloidal or gelatinous substances in the liquid.

The wire wound filter cartridge can filter out particles much smaller than the pore size with a larger filter hole, so filter micron rating is often called a precision filter cartridge.

How to Choose the String Wound Cartridge Filter?

Selection of wire wound filter cartridge

Due to fierce competition, most 0.5 micron replace water filter cartridge manufacturers are competing to reduce costs. The main methods and adverse effects are:

①. Simplify the winding method. Although the production efficiency is improved, particle water filter the filter channel of the filter cartridge is largely blocked.

That is, blind holes are formed (simplification of the winding method will cause the surface diamond-shaped holes to be intercepted by the lower yarn to form blind holes), pure filter replacement which makes the wire-wound 0.5 micron replace water filter cartridge degenerate into replace sediment filter surface filtration 0.5 micron replace water filter cartridge.

②. Change the inner and outer diameter standards to reduce the thickness of the 0.5 micron replace water filter cartridge.

Although this can save yarn raw materials, replace water filter cartridge will cause the filter layer to become thinner, the filter channel is shortened, and the filter effect is deteriorated and the stability is reduced.

③. Use inferior raw materials. Although this can reduce costs, it will cause corrosion of the 0.5 micron replace water filter cartridge.

Therefore, when selecting a 0.5 micron replace water filter cartridge supplier, replacement cartridge you should check whether it has a complete filter cartridge quality management mechanism and whether stainless water filter has the ability to ensure the quality of the filter cartridge.

Pay attention to 10 inch sediment water filter the following issues when selecting wire wound filter cartridge:

1. Observe whether the filter hole of the 0.5 micron replace water filter cartridge is penetrated, and the filter cartridge with a large number of filter holes blocked and blind holes has lost the effect of the winding filter cartridge.
2. Check the inner and outer diameter of the 0.5 micron replace water filter cartridge to see if the filter level has been reduced.
3. After using for a period of time, observe whether 10 inch 20 micron water filters the yarn and skeleton of the filter cartridge are corroded. Corrosion will not only 20 inch sediment water filter weaken the filtering water effect, but also cause contamination of the electroplating solution.

We need to consider the use of the 0.5 micron replace water filter cartridge. If it is the 0.5 micron replace water filter cartridge above the seawater desalination, our inner frame needs to use PP polypropylene filter frame.

If it is condensed water polishing, string filter we need to use SS stainless steel frame. It is recommended to use high temperature resistant fiberglass yarn.

There are four components in a string wound cartridge filter

1. Inner Core
2. Yarn
3. End cap
