How does a centrifugal water filter work?

Published in Water Filtration 1 min read

A centrifugal water filter works by using centrifugal force to separate particles from water, similar to how a washing machine spins water out of clothes.

Here's a breakdown of the process:

  • Feed and Acceleration: The water, containing particulate matter, enters the centrifugal separator through a feed pipe. This mixture is then directed into a distributor. The distributor accelerates the water until it reaches the rotational speed of the rotor.

  • Centrifugal Force Generation: The heart of the filter is a high-speed spinning rotor, often cone-shaped. This rotor generates a strong centrifugal force.

  • Separation Process: Due to the centrifugal force, the denser particles (sediment, sand, etc.) are forced outwards towards the wall of the rotor. The cleaner water, being less dense, migrates towards the center.

  • Collection and Discharge: The separated particles collect along the outer wall and are eventually discharged. The clean water is extracted from the center of the rotor and discharged as the filtered output.

In summary, a centrifugal water filter uses rapid spinning to create a centrifugal force. This force separates heavier particles from water, effectively filtering the water.
