Abstract

A modular filter for gases liquid and particulate matter is disclosed, the filter comprising at least two porous ceramic or ceramic modules. A regenerative filter is also disclosed comprising a means for filtering; and a means for regenerating said means for filtering, said means for regenerating being integral with said filtering means. A method for coating articles with a conductive coating is also included. Devices which may be used in conjunction with both modular and/or regenerative filters are disclosed.
