Paper Industry Filter Element: The Ultimate Guide

Paper industry filter element ensures cleanliness of oil, bleaching chemicals, water, paper additives, seal flush, etc.

In short, it solves all the contamination problems.

But, how can you get a quality paper industry filter element?

Your answer is in this guide. It covers every aspect of filter elements for the paper industry.

Let’s get started.

What is Paper Industry Filter Element?

According to Machinery Lubrication, a paper industry filter element uses filtration media to resolve contamination problems.

The filtration process occurs within the media, which basically comprises of intricate formation of tiny fibers.

Always go for a filter that can eliminate as much dirt as possible.

At the same time, it should allow the liquid to move through the filter in an efficient way.

Of course, the design of filter is such that fluid flows with minimal resistance.

This may be getting a little bit complex for you right now, right?

There is no cause for worry- I’ll explain.

Features of Paper Industry Filter Element

Paper industry filter element has two main components.

First, we have the design.

And, second, the filter media.

Therefore, whenever you’re looking for a good paper industry filter element, you should focus on:

  • Height
  • Type of liner
  • Seal design
  • Inside diameter
  • Outside diameter

How Paper Industry Filter Element Works

The paper industry filter media has four basic mechanisms of trapping particles.

These include:

  1. Diffusion
  2. Inertia impaction
  3. Interception
  4. Sieving

Even here, it is the particle size that determines the filtration process.

Now, let’s explore some of the above aspects:

a) Inertial impaction

It is perfect for situations that involve bigger particles in the flow stream.

Normally, the particles are heavier than the surrounding fluid.

For this reason, the fluid actually enters the fiber space.

As a result, the fibers will eventually trap particles in the fluid.

Are you still finding this complex?

Check out the figure below.

b) Diffusion

Diffusion works best for small particles.

But why?

Viscous fluid does not hold such particles.

Therefore, it is much easier for the particles to move by diffusion in the flow stream.

As these particles move with the flow stream, they collide with the fiber.

As a result, the fiber traps the particles.

c) Direct interception

This works best when you are dealing with the mid-range size particles.

Such particles are not usually small enough to diffuse with the fluid.

Also, they are not large enough to have inertia.

They normally move with the flow stream.

Eventually, they bend along with it through the fiber space.

Consequently, the particles collide – filter fiber traps them.

d) Sieving

Sieving is common in most fluid systems.

It is a perfect mechanism in situations where the particles are too big.

Such particles are actually too large to fit in between the spaces in the fiber.

You can use any of the above technique for your paper industry filtration process.

Choosing any of these techniques will depend on the situation at hand.

Take for example:

For interrupted flow, you cannot use interception and inertia techniques.

They are less effective.

Remember, a number of lube machines use diffusions and sieving mechanisms.

Besides, you can decide to mount filters in parallel like in the image below.

With this, you can filter up to 200 gpm of fluid.

To get top-notch results, ensure all its parts are in a good working condition.

Remember, pressure variance is one of the factors that come into play here.

So, ensure all liners are structurally sturdy.

In this case, the product withstands high pressure.

At the same time, it can facilitate a proper flow.

You need to settle for a product bearing a top seal design. It must be leak free.

Asides from that, it should bear a long-lasting seal or gasket.

BunaN material works quite well for most of the standard gaskets.

Moreover, media potting is important here.

This is what holds the media in place on both ends.

Remember, it is crucial to apply the potting fully on the two ends of the media.

As a matter of fact, the aim is definitely to avoid leaks.

Also, the temperature will affect its performance.

Therefore, you need to monitor it at all times.

You can go for epoxy potting.

This is one of the ideal materials since it works for many applications.

In the inner section of the filter element, there are a number of variations.

These include the pleat concentration, pleat depth or thickness.

That seems complicated, right?

Take a close look at the image below.

With that in mind, let’s now focus on the selection criterion.

Selection Criteria for Industrial Filter Element

There are basic questions you should ask yourself before buying a paper industry filter element.

These include:

  • Where do I intend to use the filter?
  • What level of cleanliness do I need to achieve?
  • What is the type of oil in question?

Apart from this, you should consider fluid’s viscosity.

As a matter of fact, there exists a wide range of machinery lubrication applications.

Obviously, oil viscosity will determine how it passes through the oil fibers.

But, the question – How can you improve efficiency?

It is pretty simple.

You only need to employ heating techniques or add polymers.

The essence is definitely to make the liquid less viscous, and that results in easier filtration.

You can achieve the most desirable results by mounting a number of filters in parallel.

However, it has to be the sort of media specifically designed for the more viscous fluids.

Of course, you must consider flow issues and duty cycle.

At times, components such as cylinders may cause flow variations.

This is commonly referred to as the pulsating flow.

By the way, it causes major problems in the various filters in the paper industry.

The kidney loop is a filtration mechanism that enables you to achieve efficient and consistent flow.

Remember, the micron size rating is a determining factor in the filtration exercise.

It needs to be changed from time to time. When you reduce the size, it traps more particles.

In short, as your source for paper industry filter element, pay attention to all these.

Applications of Paper Industry Filter Element

The paper industry filter element is a very useful product in a wide range of applications.

But before narrowing down to the specific applications, there are a few things you need to know.

Ensure you are working with products free from defects.

That is specifically in both workmanship and material.

In case you notice any defects during or shortly after purchase, it is important to let the supplier know immediately.

As a matter of fact, proper installation is easier said than done.

Install the filter elements properly in order to attain top-notch efficiency.

You will be compensated by most of the providers for reasonable complaints.

However, most of them won’t offer compensation on failures resulting from negligence or misuse.

There exist a wide range of paper filtration applications.

Of course, the need for each application will vary slightly.

Having said that, let’s focus on some of the most common applications:

Paper industry

Paper industry

· Surface treatment

Filtration plays a major role here.

Filtration works to uphold high-quality standards of the incoming products.

During surface treatment, you will come across sub-sections such as the calcinated clay, defoamers, and the insolubilizers.

Paper industry filter element plays an integral role here.

· Water treatment

The pulp and paper industry heavily relies on water to carry out a lot of its production activities.

The different systems usually utilize white water, fresh water or the used mill water.

As the plant operator, you must ensure proper filtration of the water.

Besides, this industry uses over 50 cubic meters of water.

Since water is a scarce resource, you may wish to recycle it.

Therefore, you will need a paper industry filter.

· Wet end additives

This particular industry relies on wet end additives in a major way.

However, these additives can turn out defective with continued usage.

Eventually, they cause interruptions or even damage parts.

At this point, using the industry filter element can be a perfect alternative.

Proper filtration protects your equipment.

Thus, you can produce high-quality paper products.
