Abstract
A method for manufacturing wastewater filtration plates uses a flowable composition including pre-ceramic raw material. The flowable composition is extruded to form a thin plate preform. Carbon-containing material is included in the flowable composition and/or added to the surface of the thin plate perform during or after extrusion thereof. The carbon-containing material is preformed carbon filaments or carbon-fiber precursor material. The thin plate preform is subjected to elevated temperatures to convert the pre-ceramic raw material into porous ceramic with carbon filaments embedded therein or disposed on the surface of the finished ceramic plate.

A method for manufacturing filter plates for water treatment, comprising:
- providing a flowable composition including pre-ceramic raw material and carbon-containing precursor material;
- extruding the flowable composition to form a thin plate preform;
- subjecting the thin plate preform to elevated temperatures to convert the pre-ceramic raw material into porous ceramic;
- and
- generating carbon filaments from the carbon-containing precursor material by virtue of the subjecting of the thin plate preform to elevated temperatures, the carbon filaments being embedded in the porous ceramic.
A method for manufacturing filter plates for water treatment, comprising:
- providing a flowable composition including pre-ceramic raw material and pre-formed filaments;
- extruding the flowable composition to form a thin plate preform;
- and
- subjecting the thin plate preform to elevated temperatures to convert the pre-ceramic raw material into porous ceramic with the filaments embedded therein.
A method for manufacturing filter plates for water treatment, comprising:
- providing a flowable composition including pre-ceramic raw material;
- extruding the flowable composition to form a thin plate preform;
- during or after the extruding of the flowable composition, adding carbon-containing material to the exterior of the extruded form;
- and
- subjecting the thin plate preform to elevated temperatures to convert the pre-ceramic raw material into porous ceramic and the carbon-containing material into carbon filaments attached to the porous ceramic.
