How does Basket Filter work?
Working of basket filter
The working principle of a basket filter is relatively simple since it depends on the workflow of the individual components.
Fluid flows to the filter element via the inlet, which can either b on top or the side of your basket filter.
In the basket filter, it flows to the filter element.
The filtration takes place within the openings of the filter element.
Filter opening differs depending on the size of contaminants you want to remove from your fluid.
You can check on the micron rating when selecting the appropriate mesh size for your filter element.
As the fluid passes through the filter element, it holds unwanted particles.
The filtered fluid flows out of the filter element via the outlet of the basket filter.
Also, the unwanted particles flow down to the basket filter housing.
The process continues until when there is clogging of the filter element.
Clogging is due to the basket filter housing attaining its maximum dirt holding capacity.
You can have different dirt holding capacity for your basket filter housing, depending on your filtration requirement and the size of your application.
Clogging limits the efficiency of your filtration; hence you need to stop filtering your fluid when this happens.
To remove the clogging effect, you have to clean your basket filter.
This can vary depending on the type of your basket filter.
Can Basket Filter Handle Large Flow?
A basket filter can handle the large flow.
This is due to the presence of an inbuilt filter basket whose design allows for large flow.
The basket filter also has a high dirt holding capacity, which enables continuous high flow filtration of your fluid.
The availability of the inlet and outlet opposite each other facilitates a large flow of the fluid.
Both the dirt holding capacity and the metal surface filter ensures continuous filtration.
What is the Dirt Holding Capacity of Basket Filter?
The dirt holding capacity is the number of contaminants a given basket filter can hold during the filtration period without compromising on filtration quality.
Different basket filters have different dirt holding capacity.
The choice of which one to select depends on the size of your filtration and the operational duration.
For a larger filtration, you will need to have a larger dirt holding capacity for your basket filter.
This ensures continuous filtration enabling you to clean only after filtration.
The operational duration is the duration you are going to work.
If your basket filer is going to operate for long, then you need a large dirt holding capacity.
This gives you continuity for your filtration process.
