Mesh Filter: Choosing an In-line Filter

Filtration is filtration unless it involves technical things mesh filter for separating particles

It is a well-said saying that filtration is filtration. However, when it comes to mesh filter filtration, it is something more technical than the usual process. It is because this involves particle separation. And particle separation is not as simple as it may look. Therefore, the easiest way to understand and get the idea of particle separation is to look at filter mesh.

In technical terms, one way to describe the filter mesh is a surface-type filtration material. It is because in this type the particles gather or are collected around the surface of the mess. Moreover, the role of the filter is to separate the particle that fails to pass through the mesh.

Similarly, its primary role is to get itself cleaned with the help of the backwashing process. Hence, this article will help you to develop a picture of what is mesh filter and how it works.

What Is the Role of Size in Mesh Filter?

The size of the mesh filter is as important in separating particles as catching fishes out of a fish net. By this hence it means that the size of the net that catches salmon fish is not close enough to catch minnows. Eventually looking for a more useful filter. Moreover, one important thing to keep in mind is the difference between mesh number and mesh size. Both are different units.

What Is Mesh Number?

The most common thing that people have observed is the US Standard number to describe mesh size. This size describes the opening of the mesh per inch. Consequently, the large the number the greater will be the number of openings per inch and the smaller will be opening in the mesh. For easy understanding, you can convert US standard mesh to inches, millimeters, and microns as well.

What Is Mesh Size?

The actual opening size in the mesh is what we refer to as Mesh size in the mesh filter. We usually or demonstrate these sizes in inches, microns, and millimeters. For more clarification, a single micron is equaled to the thousandth of a millimeter or one twenty-fifth thousandth of an inch.

What Is the Ideal Mesh Filter Size and Number?

Strands are commonly used in the weave. The diameter of the strands plays a key role in the opening of the filter mesh. Similarly, with this criterion, if we have a higher mesh number, the strand covers the most surface area. We usually denote the surface area of the mesh as a particular percentage of the total area of the mesh. It moreover carries an abbreviation as Percent Open Area as (POA). This eventually exhibits that with greater the POA, greater is the opening, and therefore flow will also be greater.

How to Select the Right In-Line Filter

Selecting the in-line mesh filter is a crucial job. It consequently becomes more critical when someone is looking for a miniature filter. To select the right filter for your system, there are hence some steps that one should keep in mind. Let us discuss each in details:

Particle Separation

To makes things clear, first we must explain that filtration is the process that involves the separation of particles from liquid or gas streams. Following are the steps involve in the filtration process.

• It, in fact, separate the particles from the flow. The system, however, depends upon what you really need to separate from either liquid or gas.
• It also helps in removing the gas particles from the liquid. This thereby happens when bubbles are causing serious issues.
• It, similarly, helps to separate liquid from gas. It happens most of the times where there are sensors involves that gets affected when liquid comes into contact with them

Chemical Compatibility

The next step involves studying and analyzing the chemical compatibility of the mesh filter and filter elements. It is because some acids, caustic and other organic solvents are very critical and hence make the selection of filter a crucial task. It happens because reactivity thereby is not only limited to extreme chemicals. However, water, oil, and other materials can also leach chemicals from filter materials. Moreover, the higher temperature also affects the leaching of the chemicals.

Operating Condition

Let us accept this very fact that condition matters a lot in every process. Similarly, the effects of the condition are way more than one can even imagine. By this, it means that a filter may just work fine when it is operating at room temperature. Nonetheless, the same filter eventually faces trouble when the temperature of the filter rises to the boiling point of water.

Furthermore, problems may persist if there is high pressure involved in the process. It states that with high pressure there are chances that the fluid eventually gets thick thereby choking or blowing the filter elements. Therefore, before finalizing the mesh filter it is imperative to look for the following elements:

• Determination of the temperature of the fluid that is passing from the filter.
• Existing pressure of the system including the pressure drop at the filter.
• If the thickness of the fluid is so high that it may blow away the filter elements.
• The level of the maximum volume that a filter can handle at ease. It eventually requires some preemptive testing.
• Last but not least is the consideration of particle size. Identification of the right filters for the right particles is the true job.

Physical Connection

One of the basic and most pertinent factors to consider is the attachment of the filter with the system. This implies that if the attachment process involves or requires stopping the fluid flow or not. For this reason, hence, there are some suggestions that may help you in this regard:

• For soft tubing, the recommended connections are barbed connections.
• However, for machinery, one needs to go for a Threaded connection as it works well.
• For easy and faster installation as well as a replacement one must put hands on a Push-in connection.
• For keeping things nice and neat one must apply valve connections which are quick and easy.
• Last but not least is to apply a configuration that practically fits your system.
