How To Clean a Mesh Filter: Understand and Identify the Right Method

Filtration

In the world of filtration, system operators and engineers are concerned about the accuracy of their operation, regardless of what is being filtered. This requires best practices to be integrated into the filtration process, especially when cleaning the filter media.

Mesh filters are proven to be versatile filter media that delivers a nice balance of several beneficial qualities. Of these qualities, its cleanability stands out amongst similar options as it helps prolong its performance.

That said, how exactly do you clean a mesh filter.

W.S. Tyler has helped customers understand and utilize the possibilities of woven wire mesh filters for over 140 years and is here to ensure you know how to maintain them properly.

It’s for this reason that this article will cover:

  • What a mesh filter is
  • The importance of cleaning a mesh filter
  • The methods used to clean a mesh filter
  • What cleaning method you should use


What Is a Mesh Filter?

Mesh filters are a calculated assortment of metallic wires, typically stainless steel, interlocked together after a centuries-old weaving technique is applied. Now, as this weaving process is monitored closely, high-quality mesh filters feature pore openings that deliver the precision and rigidness needed to provide optimal filtration.

To ensure your filtration needs are met, all aspects of the mesh filter can be customized to accommodate your operation. This includes the mesh count, wire diameter, weave pattern, layer configuration, and alloy.


Why Clean My Mesh Filter?

Regardless of what your filtration process looks like, the effectiveness of your mesh filter is the true key to success. That said, obstacles such as blinding, plugging, and overall debris buildup are inevitable.

This why cleaning your filter is essential.

Implementing a regular cleaning routine in your maintenance schedule will keep your mesh filter free of any contaminant particle plugging or surface accumulation. In addition, this will ensure your filter system maintains adequate throughput and accuracy for longer.

Failure to properly clean your mesh filter can lead to damaging backpressure, causing your equipment to run less efficiently and increase energy expenses.

 

What Methods Are Used To Clean Mesh Filter?

There are currently three predominant cleaning methods you can use to remove residual debris from your mesh filter. These methods are backflushing, pressure washing, and chemical cleaning.

Backflushing

The process in which the flow of a substance is reversed within the filter system, purging the filter media of any plugged or accumulated in the openings of the filter. This is an essential step to cleaning filter media as removing the hard-to-reach particles can help ensure you maintain compliant throughput.

Pressure Washing

Pressure washing is the cleaning method that utilizes a pressurized jet of water to remove stubborn particles that can sometimes be difficult to remove. While this method minimizes the amount of manual scrubbing needed, it is not as effective as backflushing when attempting to remove particles that have become plugged in the openings.

Chemical Cleaning

Chemical cleaning is the process in which contaminant particles are removed from the surface of a mesh filter using various chemicals, such as detergents, solvents, and alcohol. This process is relatively manual and is the least effective against plugged particles.

 

What Method Should I Use To Clean My Mesh Filter?

There are several factors that you must take into consideration when determining what cleaning method is suitable for your filter mesh. The first thing you should consider is the equipment type and installation condition.

To explain this further, let’s say you are using a POROSTAR sintered porous filter. These filters are generally used as filter plates in larger equipment, such as a nutsche filter dryers. These systems aren’t necessarily designed to be backflushed.

That said, because these filter plates are durable and there is room within the equipment, clean in place (CIP) techniques are often used. This means that the surfaces that come into contact with the material being filtered can be cleaned using a pressure washing or chemical cleaning method without disassembly.

The alloy of the mesh filter itself should also be taken into consideration when selecting the cleaning method. As many mesh filters are made from stainless steel or hastalloy, they can withstand all of the cleaning methods listed above.
However, no matter what alloy you use, the cleaning method must align with the durability of the alloy.

Increases Your Filtration Throughput Without Sacrificing Accuracy With Three-Dimensional Mesh Filters

No matter what your filtration process looks like, odds are the effectiveness of your filter media is always top of mind. To ensure your mesh filter continues to deliver accurate results, it is vital that you properly clean it regularly.

Now, as you continue to fine-tune the accuracy of your operation, you must explore the innovative mesh filters on the market, such as three-dimensional mesh. This will help you identify if the qualities three-dimensional mesh has to offer can be used to improve your filtration capabilities.

With over 140 years of woven wire mesh filter experience, W.S. Tyler strives to help you make the most out of your filter system.
