When we choose a cartridge, one question that is always around is what the micron rating of our cartridge should be.
To figure this out, we need to know what is the micron rating of a cartridge. Then, according to our real operation conditions, selecting the right filter cartridges.
We get a lot of products that refer to microns so today we are going to dive into that a little bit to help you understand a lot of micron. This blog post is designed to help you figure out what a micron is and how to choose the micron rating of your cartridge.
Manufacturers of microchips and wires occasionally substitute the micron, a unit of measurement that is officially outmoded, for the micrometer, which is one-millionth of a meter.
It is denoted with the symbol: μm. However, in the filtration industry, a micron is also a very important factor.
To make it more intuitive how little this is, red blood cells are roughly 7-8 microns in diameter, whereas a micron is comparable to the size of one grain of freshly ground flour.
A filter’s micron rating describes the size of the holes or pores in its surface and, consequently, the size of the particles it can remove from the water it filters.
The smallest particle size that each cartridge filter is capable of eliminating is indicated by its micron rating. All types of filter cartridges have micron values ranging from 50 microns to 0.035 microns (Pleated membrane cartridges).
For filtration, micron rating can be Nominal rating or Absolute rating. A nominal rating means that 95% of the particles with a diameter of that micron will be captured by the filter cartridge. 99% of the particles will be removed by the filter, according to an absolute rating.
After realizing what micron and micron rating are, it is simple and easy to select a appropriate filter cartridge. As we mentioned above, micron rating determines the smallest particle size, which can be removed. Choosing a filter cartridge is depend on your water supply.
You just need to make sure what kinds of liquids you want to filter or what kinds of particles and contaminants you want to gain from the liquids.
You can based on the data details of every filter cartridge, choose filter cartridges. But one thing you should notice, that the quality of water supply various from different places, this is also an important factor you need to consider.
Sometimes, filtration is not only filter out the contaminants, but also collect something we need, such as catalyst. The size of the things you want to collect is another consideration for selecting filter cartridges.
According to the different requirements of micron ratings and other factors, our high flow filter cartridges and melt blown filter cartridges are preferred by many customers.
As mentioned above, various micron ratings are available for filter cartridges. Different micron sizes can determine different removal of particles.
Bacteria and viruses cannot be removed from liquids by filters having a 10 micron rating. However, 10 micron is still incredibly small and can help various industries, from chemical plants to the oil industry, because of how much they can filter. 10 micron rated filters frequently clog, just like those with micron values lower than this.
Large amounts of particles are removed from liquid by filters having a 5 micron rating. While there are filters with smaller micron ratings, those below 5 micron are more prone to severe clogging or rapid buildup of debris. The filter fills up more quickly the lower the micron rating.
It is occasionally advised to utilize more than one filter when there are numerous particles, dirt, and debris to be filtered in order to avoid clogging. Many industries, notably the food and beverage sector, benefit from a 5 micron rating.
1 micron Filters can help reduce bacteria and cysts because their pores are too small for them to pass through with other particles smaller than one micron.
Besides other large particles, 0.5-micron filters can block parasitic cysts giardia cryptosporidium, chlorine, and organic chemicals.
Micron rating is an important factor to the effectiveness and filtration performance of a filter cartridge or a filter bag. If you want to get a perfect filtration result, it is essential to select the right micron rating for your operation condition.
