What happens in the process of filtration?

filtration, the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles. Either the clarified fluid or the solid particles removed from the fluid may be the desired product.

What is filtered material?

Filtration is the process of separating suspended solid matter from a liquid, by causing the latter to pass through the pores of some substance, called a filter. The filter may be paper, cloth, cotton-wool, asbestos, slag- or glass-wool, unglazed earthenware, sand, or other porous material.

What is the material left in the filter?

The fluid that passes through the filter is called the filtrate, and the solid material that remains on the filter is called the residue.

What are the materials used in a filter process?

The filtration materials includes the soil, sand, cotton, sieve, charcoal and others depending upon the filtration process.

What does filtration remove?

Filtration is a process that removes particles from suspension in water. Removal takes place by a number of mechanisms that include straining, flocculation, sedimentation and surface capture.

What remains on the filter paper after filtration?

The solid particles which remain on the filter paper after the filtration is called Residue.

What materials remains in the filter cloth or paper when filtering is used to separate mixture?

The solid that remains on the filter paper is called the residue.

Can solutions be separated by filtration?

Filtration works best when the solute isn’t dissolve in the solvent. For instance, sand and water can be seperate through filtration as both compounds do not dissolve with each other. However, sugar and water would not be seperated through filtration as they dissolve with each other.

How does a different material affect a filter?

  As the filter loads up with the stuff it catches, the resistance increases. If you want to remove more stuff from the air, you can use a filter with a different material.   The pores in these filters are much smaller, allowing the filter to catch more pollutants from the airstream but also adding more resistance.

What are the particles that cannot pass through a filter?

Solid particles that cannot pass through the filter medium are described as oversize and the fluid that passes through is called the filtrate. Oversize particles may form a filter cake on top of the filter and may also block the filter lattice, preventing the fluid phase from crossing the filter, known as blinding.

How are the filters in a plant constructed?

Filters in large plants are usually constructed next to each other in a row, allowing piping from the sedimentation basins to feed the filters from the central pipe gallery. Some smaller plants are designed with filters forming a square of four filters with a central pipe gallery feeding the filters from a center wall.

How does the resistance of a filter change?

  Going through the filter material, the air encounters resistance. How much resistance depends on the type of filter material and the amount of area.   The standard fiberglass filter doesn’t resist the air flow much, at least not when the filter is clean.   As the filter loads up with the stuff it catches, the resistance increases.
