Methods of Cleaning Wire Mesh Filters

June 7, 2023

In filtration systems, regardless of the media being filtered, the selection of wire mesh filters and the operation and maintenance of wire mesh filters are very important. This ensures high-precision filtering for optimal results.

Nowadays, wire mesh is playing an increasingly diverse and important role in the filtration industry with its unique advantages – cleanability & long service life. This makes the cleanable filter cartridge made of wire mesh more popular than disposable filter cartridges, effectively reducing use and maintenance costs.

So, how do we clean filter cartridges? With over 20 years of experience in the manufacture of filter cartridges, Boedon provides you with the following professional advice:

What is Wire Mesh?

Wire mesh is an important part of wire mesh filter, generally made of high quality stainless steel wire, which is stretched to a specified wire diameter by a drawing machine under specific high temperature process conditions, and then woven by a weaving machine in a constant temperature, dust-free and clean plant. It is characterized by precise structure, uniform mesh, good filtration accuracy and wear resistance, high temperature resistance, strong acid resistance, and corrosion resistance performance.

In order to precisely screen particles in the specified particle size range and meet the specific filtration needs of clients, the mesh, wire diameter, weaving method, layers and alloy composition of the wire mesh can be customized.

Why We Need to Clean Wire Mesh Filters?

Regardless of the filtration process, only effective filtration can be considered successful. However, successful filtration also means unavoidable problems such as mesh clogging and accumulation of impurities. Therefore, it is very important to clean wire mesh filters.

Regular cleaning of wire mesh filters can prevent problems such as mesh clogging and surface buildup, ensuring that the entire filtration system maintains adequate throughput and accuracy over a longer period of time. However, improperly cleaned wire mesh filters can cause damaging backpressure, reduce equipment operating efficiency, and even increase energy consumption.

How to Clean Wire Mesh Filters?
  • Backflushing
    In this process, the flow of media in the filtration system is reversed as a means of removing clogged or accumulated particles from the mesh apertures. This is an important step for cleaning wire mesh filters, as removing hard-to-reach particles can help ensure that the filtration system maintains compliant throughput.
  • Pressure Washing
    Pressure washing is the use of pressurized jets of water to clean stubborn particles that are normally difficult to remove. While this method minimizes the amount of daily manual scrubbing, it is not as effective as the backflushing method when attempting to remove particles that are clogged in the mesh.
  • Chemical Cleaning
    Chemical cleaning is the process of removing contaminant particles from the surface of wire mesh filters using various chemicals such as detergents, solvents, and alcohol. This process relies mostly on manual work and is the least effective at removing clogging particles.
How to Choose Proper Cleaning Method?

We can consider the following two aspects when choosing the proper cleaning method for wire mesh filters:

  • Equipment Type & Installation Conditions
    Sintered porous filter cartridges are applied to equipment that does not necessarily support the backwashing method, and the surface of the cartridge can generally be cleaned using pressure washing or chemical cleaning methods without disassembly.
  • Wire Mesh Material Properties
    Many wire mesh filters are made of stainless steel, so they can withstand essentially all of the cleaning methods listed above. However, if the material is mild steel, it is easy to rust after the chemical cleaning process.

Regardless of the filtration process, the filtration efficiency of wire mesh is of utmost importance. To ensure the most accurate filtration, we need to clean it properly on a regular basis.
