How Does a Sintered Screen Basket Work?

This basket works by filtering fluid that enters via inlet port, undergoes filtration, and exits system.

The fluid will flow in the system at a high pressure level.

Once in the sintered screen basket, the basket will allow the fluid to pass through as the contaminants remain behind.

The micron rating of the basket will allow it to eliminate a certain amount of contaminants.

After the filtration process, the clean fluid will exit the system via the outlet port.

Besides, dirt will continually accumulate on the basket and after a while, it is important to clean it.

This will eliminate the chances of compromising the filtration process.

How Do you Maintain a Sintered Screen Basket?

Maintaining a sintered screen basket ensures that the filtration process is accurate and reliable.

Always inspect the basket to ensure no damages occur in the core of the basket.

Eliminate impurities timely when you notice a pressure drop so that the flow rate will not decrease.

Do not damage the stainless steel body when cleaning otherwise it will decrease the filtration efficiency.

Replace the device when you notice deformations and damages on the surface.

What is the Filtration Principle of a Sintered Screen Basket?

Filtration operation relies on constant flow, increasing the pressure drop until you reach the terminal pressure.

It reaches terminal condition when the thickness of the catalyst cake increases until the fluid flow pressure drop is maximum.

One will backwash the sintered screen basket by pressurizing with gas then opening the discharge valve.

Backwashing generates high reverse pressure which eliminates solid contaminants from the surface of the media.

A reverse flow of a clean filtrate will assist in removing solids out of the basket.

A uniform rise in pressure drop illustrates that the particle size of the feed slurry remains constant just as the slurry concentration.

Inside-out basket configuration will utilize the basket with a uniform porosity to build cakes inside the surface.

These will enhance the particle removal and the backwash efficacy.

The recovery pressure following backwashing will slightly increase after you condition the media.

Also, it should be within 2 to 3 PSI of the clean flow’s pressure drop.

The recovery pressure drop has to be stable to enable a consistent performance.

Also, following a good backwash process will ensure suitable media cleaning.

A change in the temperature will influence viscosity and the pressure drop will rise in the media.

It is therefore important to maintain design-operating temperatures in the entire filtration procedure.

Why is Porous Metal Suitable in a Sintered Screen Basket?

It offers a consistent method of eliminating contaminants, is easy to clean, and is durable.

What should you Consider When Selecting a Sintered Screen Basket Filter Element?
