Why Industrial Filtration Is So Important

14 Dec 2019 | Family

Industrial filtration is crucial to many different fields and industries. It is used both to separate particles and substances from liquids as well as to lengthen the lifespan of manufacturing equipment. From restaurants and schools to automotive and hydroelectric plants, industrial filters play an important role in treating oils, water, and coolants.

Here we take a look at a few of the different types of industrial filtrations.

Wastewater Filtration

The filtration of wastewater can be achieved by employing the use of a sludge dewatering system. This separates solids from liquids and results in clean water that is then usable in sewers. There are two main sludge dewatering system types – those that use gravity alone and those that utilise a vacuum producer. Many industries choose to invest in a vacuum producer system as it dramatically decreases sludge disposal costs.

Sludge dewatering systems usually consist of a conveyor belt supported by a heavy-duty tank. The wastewater passes through a filter which separates out the solids onto the conveyor belt. The vacuum producer takes air from beneath the belt and helps dry out the solids to the point where they are ready to be moved along the conveyor belt for disposal. Using a vacuum producer results in much drier solids which in turn leads to lower costs when it comes to disposal.

Industrial Coolant Filtration

The purity of coolant has a direct bearing on the effectiveness of machinery and the lifespan of the coolant itself. This is why industrial coolant filtration is so important. Contamination of coolants occurs when tiny particles are introduced during various production processes. The use of magnetic filtration drum separators assists in the extraction of ferrous particles from the coolant.

Magnetic coolant filtration works by directing the coolant into a rotating drum that contains a strong magnetic field. The magnetic field attracts the ferrous particles, thus separating them from the coolant. A blade is situated above the drum, helping to discharge the particles as the drum rotates, leaving the coolant clean and ready to be reused.


Centrifugal force is an incredibly effective method of separating liquids and solids and is therefore often used for industrial filtration purposes. There are a wide variety of centrifuges available, including oil centrifuges to treat waste vegetable oils, used engine oil, and industrial oils, as well as those suitable for wastewater, solvents, biodiesel, and emulsions. Some centrifuges require manual cleaning, whereas others are fully-automated and are self-cleaning.

Round-Up of The Benefits of Industrial Filtration

For many industries and businesses, industrial filtration is essential for day-to-day operations. The benefits of employing a filtration system are clear:

  • Removes particles and substances from liquids
  • Enables liquids, oils, and coolants to be reused
  • Protects tools and machinery
  • Stops contamination from spreading
  • Cleans water
  • Improves the overall performance of equipment

It is easy, then, to see why so many companies choose to invest in top-quality industrial filtration systems and why not doing so could be a costly mistake.
