A ceramic filter operates on the same principles as fabric and compact filters. The gas flow is fed into a large chamber, into which ceramic filter material is introduced.
The ceramic filter can be made of aluminium oxide, silicon oxide and silicon carbide (amongst others).
The material can be implemented in a variety of ways. It is possible to adapt it to fabric, felt-fibre, felt, sintering elements or filter candles.
The high pressure drop in ceramic elements is reduced by using heterogenic materials such as silicon carbide grains and fibres, but primarily by using a membrane on the carrying system. A 100 – 200 µm heterogenic membrane of silicon carbide grains and ceramic fibres is fitted to the system using a silicon carbide carrying material.
Filtration systems can standardly be fitted with 16, 36, 64, 144 and 256 filter elements. These filter systems can also be placed in a series or parallel set-up.
Residual emissions for the various installations amounts to 1 mg/m³.
 Filter medium. Life-span is determined by the set-up and type of application.
The energy used by ceramic filters can be compared to that used by fabric filters and is mainly determined by the cleaning system and the filter resistance.
mainly determined by the filter element .
separated dust are determined by the type of residue.
 In contrast, fibre elements have a relatively low pressure drop, they are cheaper and have a low weight.
