Filtration Medium

It functions by filtering out contaminants and other impurities from the process fluids or water.

The external surface will capture large contaminants while the internal side will capture small contaminants.

Gaskets or O-Rings

This part will create a durable and strong seal between two separate parts

. It assists in preventing leakages from occurring during the filtration process.

How does a PP Filter Cartridge Work?

PP filter cartridge works by holding dirt and preventing it from passing the filtration medium with clean water or process fluids.

Also, it has a high dirt holding capacity and efficiency as it has a high surface area.

Besides, it also operates well under low pressure which other filter cartridges find hard to work in.

Here is how a PP filter cartridge works:

Step one: Installation

In this step, make sure you install the PP filter cartridge correctly.

This will ensure it works efficiently in the application of choice.

Step two: Filtration

Here, you will allow the water or process fluid to pass through the PP filter cartridge.

The fluid will pass through the filtration medium as the contaminants and dirt remain behind.

Also, the large surface area of the filter makes it possible to have a high dirt retention capability.

Besides, allow the fluids to pass through the system under low pressure.

This will allow it to take more time in the system thereby increasing the filtration efficacy.

The inner core offers a robust strength that enables it to allow water to pass through and contaminants to remain behind.

Also, the external filtration layer allows filtration to take place with no media migration.

Step three: Final

After the filtration process, clean fluid will flow out of the system leaving dirt behind.

How do you Clean a PP Filter Cartridge?

It is possible to replace a PP filter cartridge if it happens not to operate well.
