What are filters?
Filters are process equipment for solid-liquid separation of suspensions or for solid-gaseous separation of laden raw gas with the aid of a filter medium. The purified liquid is called filtrate and the purified gas is called clean gas. The required pressure difference is realized by applying pressure on the suspension gas side or by applying a vacuum on the filtrate or clean gas side.
Which filtration principles are there?
The main type of filtration principles are:
Surface filtration (before beginning of cake filtration and in cross-flow filtration)
Cake filtration through a building up filter cake
Depth filtration in porous filter media
Filters can be differentiated based on:
Driving forces for fluid passage through the filter medium, such as gravity, pressure, vacuum, or centrifugal force.
The filtration mechanism, whether it involves direct separation of solids or their accumulation (cake formation) on the filter medium.
The process objective, including solid separation and drying, liquid clarification, or purification of a gas stream.
The operating cycle, where industrial filters can work intermittently or continuously.
Which types of used filters do we offer?
