This is the point where you will pass the fluid through the lenticular filter media to get rid of impurities.

· Post Filtration Flushing

After the filtration process, you will clean the lenticular filters through the post-filtration flushing method.

This will assist in getting rid of the particulate matter or contaminants trapped in the lenticular filtration media.

How Does Lenticular Filter Module Regeneration Work?

Forward flow will provide the most effective means of reducing fouling in filter media depths.

In this case, you will perform regeneration well before the terminal.

Here are the steps to follow when doing a forward flush regeneration.

  • You can use the outlet or drain valve to clear the housing of the product.
  • After that, you will begin a forward flow of the ambient water and increase temperature to 120 – 140 F.
  • You should set the flow of water to equal the flow rate of the product that you are filtering.
  • As this continues, you need to take a keen note on the pressure by doing proper records.
  • After a period 0f 5 to 10 minutes of flow, you will hold the filter in a soak phase for about 10 minutes.
  • As soon as the 10 minutes is over, you will resume forward flow for about 10 minutes.
  • Finally, you will drain the lenticular filter to get rid of the water from the system.
How does Lenticular Filter Work?

It is important to have the right idea on how a lenticular filter will work before you begin using it.

Here is a step by step procedure through which a lenticular filter works.

Inbound flow of the Fluid

You will allow the fluid to enter the lenticular filter through the inlet valve after pre-filtration flushing.

The rate of flow will depend on the rate of flow of the liquid as well as the pressure of the flowing liquid.

Actual Filtration

As the fluid flows through the lenticular filter, it interacts with the filtration media.

Lenticular filters have a wide surface area that the fluid will pass through thus increasing the efficiency.

The filtration media will get rid of the contaminants or impurities from the flowing fluid by trapping them.

The pores are of a particular size and does not allow anything larger than the actual size of the fluid.

It ends up trapping the impurities and allowing the clean fluid to proceed.

Outbound Flow of the Fluid.

Finally, you will release the fluid and allow it to flow out of the lenticular filter.

After that, you have to make sure that you clean the lenticular filter through post-flushing of the elements.

How do you determine Lenticular Filter Flow Rate?

You can determine the lenticular filter flow rate by looking at the flow rate of the fluid you intend to filter.

Implying that the flow rate of the fluid is more or less similar to the flow rate of the lenticular filter.

Apart from that, you will also realize that the size of the lenticular filter will also have an impact on the flow rate.

You will determine the size of the lenticular filter by looking at the size of the lenticular media pores.

The bigger the size of the pores, the higher the rate of flow of the lenticular filters.

What is the Micron Rating of Lenticular Filter?

The micron rating of lenticular filters refers to the ability of the filter to remove particular contaminants.

You will determine the micron rating of lenticular filters by looking at the type of filtration media of the lenticular filter.

The smaller the pore sizes the higher the micron rating of the lenticular filters.

When should you Replace Lenticular Filter?

Lenticular filter element

You should consider replacing the lenticular filtration system especially after using it for a long time and reducing efficacy.

This means that the lenticular filter will cease to filter all the impurities according to the recommended rates.

In some cases, the lenticular filter might block due to numerous contaminants on the filtration elements.

In this case, it is advisable to clean the lenticular filter and if the problem persists you will replace it all together.

What is Carbon Lenticular Filter?

Carbon lenticular filter is a device that uses carbon elements or module in the process of filtering different fluids.

It produces higher efficiency in comparison to other forms of filtration media in the lenticular filters.

Which Design Feature make Lenticular Filter Unique?

When looking for a good filtration media, you have to look at the features that makes it unique.
