Chat Now!### Cyclonic separation - Wikipedia

Cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation When removing particulate matter from liquids, a hydrocyclone is used; while , towards the narrow end of the cyclone, the rotational radius of the stream is reduced, thus separating.
