How to choose suitable stainless steel liquid filter housing?

March 22,2022

As we all know, stainless steel liquid filter is indispensable equipment in our life and work, so we should have a certain understanding of its use and selection methods, so now hurry to see the selection method of stainless steel filter equipment with us!


  1. According to the filtering accuracy


The decision of filtration accuracy may be the most troublesome problem, because the range of accuracy is very wide, and if we want to remove the pollution visible to the naked eye, we have to choose 25 micron equipment; If you want to remove 1 micron of liquid or 5 micron of cloud; To remove the smallest bacteria, 0.2 micron equipment is required, so the filtration accuracy is also different if the use environment is different. The current filtration accuracy unit has two different classifications: absolute accuracy and nominal accuracy. Absolute accuracy refers to the ability to remove particles with marked accuracy 100%, which is impossible for any kind of filtration equipment, but an unrealistic standard. Others belong to nominal accuracy, which is the most important standard when selecting equipment and it is also our trouble, because there is no standard jointly recognized and implemented in the industry. In the face of such problems, selectingmore experienced liquid filter housing supplierswill help to select the filtering accuracy, and the real solution can only be determined after use.


  1. According to filtration temperature and viscosity


Professional filter equipment providers can accurately calculate what kind of filter equipment is needed in various industries, such as how many filter elements to install, how much flow rate each filter element bears, initial pressure drop, etc. if we can provide the performance of filter media, such as impurity content, it is also very useful for our choice.


  1. Design of filtration system


Design includes many different aspects. For example, what kind of pressure source should we choose? How much pressure is needed? Is it necessary to install two sets of filtration equipment in parallel? How to match coarse filtration with fine filtration? Is it necessary to install check valve or other devices? This series of problems should be considered completely at the beginning of design.


  1. Selection of filter materials


When selecting materials, the first thing we need to do is to select the corresponding available filter materials according to the properties of the filter media, and then evaluate the operation temperature, pressure, pH value, etc. one by one to remove the unsuitable filter materials.


Matters needing attention


It should be noted that different uses of products are also an important factor to be considered. For example, the filter materials used in the production of drugs, food, cosmetics and other products must be materials approved by FDA; the production of ultra pure water requires pure filter materials without release; when filtering general gas, you need to choose hydrophobic materials and so on.
