Production of Melt Blown Filter Cartridge

• The production process of melt blown filter cartridge is as follows:
• Polymer raw materials
• Screw extruder (melt extrusion)
• Filter device
• Metering pump
• Melt blown die assembly
• Melt trickle stretching
• Cooling receiving device
• Winding forming device

Use of Melt Blown Filter Cartridge

When using the water filter industrial water system purification, we must judge according to water filter house the impurity content of the filtered medium in the cartridge filter water treatment system and the type of impurity.

Usually the melt blown filter cartridge is installed in the filter to act as the membrane group that protects the reverse osmosis system filter housing.

As water filter industrial pre-treatment, pp sediment filter 5 micron price the impurity content in the system is too high, secondary filtration water filter house can be used to ensure.

The RO influent cartridge filter water quality pre-filter is within the normal specified range

If there are more impurities and viscous liquids in the system filter housing, water filter pitcher replacement cartridge you can also water filter house use pre-filter Two-stage filtration, the front stage pre-filter is used as pre-filtration, air purifier cartridge and then in the fine filtration, best sediment filter cartridge thereby extending the service life of the filter cartridge.

The filter cartridge should be installed correctly water filter house when water system purification water filter house in purifier water system filter housing.

Usually filter housing is pleated sediment filter support rod in the tank body to facilitate the installation and positioning of the filter cartridge.

 If the filter for cartridge filter water after filtration is found to be dirty, we must check whether the filter cartridge is inclined and whether the filter housing is tightly pressed.

Another problem is about the cartridge filter replacement of water filter house water system purification the filter cartridge, sediment cartridge water filters which is usually marked by the pressure difference filter housing to determine when to replace the filter cartridge.

When the pressure difference filter housing of the system rises and the pressure difference reaches 0.2Mpa, we must clean or replace the filter cartridge water system purification in time.

Secondly, we check whether the effluent filter for cartridge filter water quality is within the specified standard range. 10 micron sediment filter If one of the filter housing effluent cartridges filter water quality TSS, NN and SS, etc. exceeds the standard.

Best water filter replacement cartridges check which link in the upstream has a problem, and replace the filter cartridge water system purification if necessary to observe whether it can solve the problem.

The cartridge filter water system purification replacement life of the filter cartridge depends on the filter housing cartridge filter water quality.

Under normal circumstances, if the incoming cartridge filters water is tape cartridge filter water or surface filter for cartridge filter water, sediment cartridge 5 micron the life of the filter cartridge is three months.

FAQ about Melt Blown Filter Cartridge

Q: Will a 5 micron Melt blown filter cartridge filter cartridge remove iron?

A: If the iron settles to the bottom then a 5 micron Melt blown sediment filter (5 micron or smaller) should be able to remove the majority of the iron particles.

A cartridge filter water softener will remove up to 4 parts per million (PPM) of iron, but if used this way the resin will need to be cleaned about once a month.

The filter cartridge can intercept rust, suspended solids and colloids in the system.

Q: What does 5 micron Melt blown sediment filter mean?

A: A micron rating for a 5 micron sediment filter is a way of indicating the ability of the filter to remove contaminants by the size of the particles.

A filter that is marked “5 microns” has some capability in capturing particles as small as 5 microns.

Q: Is a 1 micron Melt blown filter cartridge better than a 5 micron Melt blown filter cartridge?

A: For example, a 5-micron Melt blown filter cartridge water system purification has larger openings than a 1-micron Melt blown filter cartridge.

Bacteria range in size from 0.2 to 2 microns in width or diameter and from 1 to 10 microns in length for the no spherical specie, so a 1-micron Melt blown filter cartridge will remove most bacteria and cysts.

If the cartridge filter water quality in the system is dirty and contains a lot of impurities, the service life of the 1-micron melt blown filter cartridge will be shorter and the cost will be high.

Usually the accuracy of the filter cartridge depends on the cartridge filter water quality, not that the higher the accuracy, the better. What suits you is the best.
