Fine Dust Filtration Process

Fine dust is a dangerous byproduct in almost any industrial sector. It has become a leading culprit in causing lung and heart diseases among the workforce. Factory workers, artisans, and other essential works suffer primarily from it, and it is also playing a significant role in increasing cancer growth.?

Human rights and many other administrative bodies have decided to pass new laws and enforce the well-being of the workforce in the industrial sector. Therefore, it has become pivotal for industries to adopt a form of fine dust filtration process.

Fine dust is invisible to human eyes. It is so tiny that it can easily fit on a strand of hair. And that’s not the worst part. It is everywhere you see fuel, oil, or wood burning. Therefore, it has become indispensable to use a fine dust filtration process.?

What Is Fine Dust Filtration??

Fine Dust Filtration is a science that focuses on separating solid particles from the air. You could say it is a form of air purification but at an advanced level. The fine dust filtration process doesn’t just work on fine dust but other materials and pollutants in the air.?

Reasons For Fine Dust Filtration?

There are two prominent reasons that branch out to move diverse reasons for fine dust filtration:

1. Material Recovery: As air is prone to carrying materials, particles, and more, the filtration process can recover the said materials.
2. Pollution Control: Evidently, the air has pollens, allergens, pollutants and more. Fine dust filtration can precisely purify the air.

It is vital to understand that fine dust particles originate from almost everywhere. Fuel, oil, wood, and other combustible materials are known for being the leading cause of fine dust production.

Apart from fine dust, there are many different particles of various sizes in the air. They could have varying abrasion values, be hot or have combustible properties, be chemically active, sticky, and more.

The smoke, smog, and other visible degraded air quality are part of the fine dust infestation.?

Designing Filtration Processes

Designing a filtration process for any level of air purification has to undergo six diligent considerations. While adopting a filtration mechanism, these six steps play a crucial role in defining the efficacy of the filtration process:

1. The size of the particle and the velocity. Depending on the industrial sector (construction, manufacturing, production, etc.), the requirement for filtration power also varies.
2. Nature of the particle. There has to be a diligent examination and research on the byproducts and other particles released in the air. After that, an apt filtration procedure is employed for the filtration.?
3. Particle density changes where you consider the inlet air and the outlet air from the filter.??
4. Balancing capital expenditure and operational expenditure. As an industry, employing the filtration process means additional expenses, and they need to be worthwhile.?
5. Maintenance of the filtration system.
6. Failure of the system and potential errors or malfunctions.?

Different Filtration Mechanisms

There are various filtration mechanisms available in the market for industries. Here is a quick overview of these mechanisms:?

1. Wet Filtration - Scrubber

Scrubbers are primarily used in industrial sectors. It is a form of the air treatment process that works to purify the air from mechanical pollutants.?

2. Cyclonic Filters

A process where a centrifugal force is used to separate particles from air or water. Cyclonic filters are primarily used for liquid-based operations. For example, water, coolants, lubricants, etc.

3. Bag Filters

These are the most commonly used filters in industries. You also find them being used in your car’s air conditioning system. Their objective is to collect dust and other particles.?

4. Electrostatic Filters

Electrostatic filters are also common and more advanced forms of bag filters. These use charged ions to trap air particles and separate the pollution. Electrostatic filters are made up of synthetic materials or metals.?

Understanding Bag Filters

Bag filters, as mentioned above, are the most common type of air filter that you can easily find in the market. They can be made from different materials and are primarily used in HVAC systems and filtration.?

Depending on the cost and material composition, bag filters can offer remarkable efficiency in filtration. Hence, they are used in every sector, from industrial to commercial. You will see their use in medical fields and even for institutional purposes.?

Bag filters are known to improve air quality and also work great against fine dust.?

Benefits Of Bag Filters

Before you consider the benefits, don’t forget to understand the size of the filter bags. Filter bag size measurement is in microns. For example, 1 micron, 10 microns, and 100 microns. The smaller the unit, the better the air filter will purify, but it will also cost more.?

With that, here are the benefits of bag filters:

• Most versatile in size and can easily filter fine dust.
• Come in various shapes and sizes and also work with many filters.
• Work great with air purifiers and more.?
• Highly affordable compared to other filters with similar filtration capacity.
• Easy to replace, low maintenance, and cost-effective.?
• Biodegradable and eco-friendly bag filters are available today.
• Energy efficient.?
• Improves air quality, and overall health index.?
