Suodatinelementti, suodatinlaitteisto ja menetelmä suodatinelementin valmistamiseksi

摘要

Magnetic elements are provided inside a ceramic filter plate for creating a magnetic field. In an embodiment of the invention, magnetic elements are located in cavities provided in partition walls which define filtrate channels between themselves. The filter plate can be used for increasing filtration capacity particularly in magnetite applications. The magnetic field causes an attractive force on the magnetic particles and thus increases the amount of material forming on the filter plate in a vacuum filter, such as a capillary action filter, conventional rotary vacuum filter or drum filter or capillary action drum filter.
