Know About Types Of Industrial Filtration You Might Need

Industrial filtration is the process of removing particles from liquids, gases, and chemicals. There are various types of industrial filtration, depending on the type of filtration needed. There are four main types of industrial filtration: oil, gas, liquid, and solid. The whole process of removing impurities, such as dust and other solid materials, from a fluid stream; happens with the help of a high-quality filter present in a machine. The process has a variety of industries and applications, such as water purification, chemical waste treatment, and power generation.

Types of Filtrations & Specific Purposes

The first type is an open system. This means that the entire system has exposure to external contaminants such as dust or dirt. An open system does not allow airflow through it, making it difficult for contaminants to pass through and reducing the time required for cleaning operations. The second type is a closed system. This type of filtration uses air filters that allow air circulation but do not allow water droplets or other liquid contaminants to pass through them into the final product during filtration. The third type is a hybrid system; this type combines both types of filtration methods into one unit so that it can be used both as an open system and as a closed system depending on what kind of product is being filtered by it at a given time.

Different types of industrial filtration methods

Sand filtration

A sand filter uses sand or gravel media to remove large particles from the flow. This type of filter has a use for water purification because it can remove many contaminants before they enter the distribution system.

Mechanical filtration

Mechanical filtration is when the impurities move out of the liquid using a mechanical force, such as gravity or centrifugal force. For example, throwing a rock into a pond would naturally float to the surface because gravity is acting on it from below; this is an example of mechanical filtration.

Chemical filtration

Chemical filtration uses chemicals to remove impurities from water or other liquids; for example, adding chlorine bleach to your tap water will kill any germs that might be present in it and make it clearer so that you can see through it better than before.

Biological filtration

Biological filtration uses microorganisms such as bacteria or yeast to remove impurities from water or other liquids; for example, adding yeast cells to your tap water will make it ferment.

Methods of Industrial Filtration

Industrial filtration is about gravity, pressure, and electrostatic. Gravity filtration is the most common type of filtration used in industries. It involves filtering fluids by means of gravity. The filter media is usually a sieve holding large quantities of solids while allowing the fluid to pass through it. Pressure filtration uses high pressure to force fluids through a filter media or separation tank. This type of filtration is with liquids that cannot be filtered by gravity or mechanical means because they would become too viscous to move through any other method. Electrostatic filtration uses electric charges to separate particles from liquids or gases.


Industrial filtrations are an important part of any industrial or commercial facility. To maintain cleanliness and efficiency, it is important to have a sound filtration system in place. Industrial filters are available in many different industries, but they all work to remove particulate matter from the air. The most common types of industrial filtration are dry-type filter—This type of filter is a static type of filter that uses suction to remove particles from the air; active carbon filter—filters use chemical reactions to remove particles from the air; and wet-type filter—it uses a chemical reaction to capture particles from the air stream, usually through adsorption onto an inert surface such as activated carbon or silica gel.

Why Are Industrial Filtration Systems Important For Manufacturing?

Why Are Industrial Filtration Systems Important For Manufacturing Industrial filtration systems are important in many fields and industries including manufacturing facilities. From food processing to power generation to pharmaceuticals industries, each industry uses specialized equipment. The equipment including its vacuum pumps, blowers, gen-sets, etc must be protected to ensure maximum uptime and long machinery lifetime and effectiveness. Many industrial processes require cleanliness and filtration not just to protect the equipment and machinery but to also protect the work environment.

What Is The Purpose Of Filtration?

The most common uses of industrial filtration include:
  • Protecting equipment from contacting and ingesting harmful contaminants.
  • Isolating and separating undesirable products from the air stream.
  • Protecting personal and work environments
  • Removing contaminants for purifying air and gas streams.
This blog explains some of the main purposes of using industrial filtration systems along with machinery and equipment filtration systems.

Protecting Equipment From Ingesting Contaminants

Contaminants that are released during the manufacturing process are highly damaging to the equipment. The main purpose of an industrial filtration system is to contain these contaminants for proper disposal. In pharmaceutical and other chemical industries, the manufacturing process can emit dangerous chemicals and by-product vapors, and aerosols which could lead to vacuum pump failure and in some cases induce a combustion event. Therefore, it is important to have an industrial filtration system in place that removes these harmful byproducts and can keep the machines running and upright. In this case, a vapor condensing trap would be used to make sure the vapors are condensed and removed effectively.

Removing Contaminants From The Air And Gas Stream

Industrial filtration is crucial in manufacturing applications including additive manufacturing, pneumatic conveying, and landfill gas collection. It helps to keep the gas and air free from contaminants during the production process, and also helps in ensuring the purity of the products formed in the process. Gas and air filtration must be thorough to ensure that all harmful and undesirable products are removed from the environment. If manufactured products contain slight impurities they will become unusable causing financial losses. Hence, filtration is an important part of any industry. Often times airborne contaminants and dust particle ingestion can cause the rejection of entire batches. To save this from happening industries use an inlet air filtration or a combination of an inlet air filter and a silencer, to protect the protection blower and keep the air and gas stream optimized and clean.

Isolating And Separating Undesirable Products From The Air Stream

Several manufacturing processes involve the efficient separation of solids, liquids, and vapors. This is accomplished effectively by using filtration and separation systems to separate the product from the air or gas stream under vacuum conditions. These specialty and filtration systems are used to separate the specific liquids, solids, and vapors from the air stream carried over the manufacturing process. This is often key to the manufacturing process. For instance, the essential oil extraction process must separate specific chemicals under the vacuum to create a usable product.

Common Industrial Air Filtration Applications

Some other common industrial air filtration system applications include:
  • Hydraulic tank breathers
  • Medical, pharmaceutical, and dental vacuum air systems.
  • Elimination of oil mist from the discharge or exhaust of vacuum pumps
  • Industrial processes that involve the use of vacuum pumps and blowers; wastewater treatment, pneumatic conveying, CNC routing, chemical vapor deposition, and steel ragging, etc.
  • Crankcase ventilation; protect the surrounding environment by trapping the oil mist vapors produced by engines and gen-sets.
  • Filtration systems are used to eliminate oil mist from different parts of rotating equipment like turbines, compressors, lube oil systems, gearboxes, and coupling guards.
