Abstract
A multiple disc filter includes a plurality of discs arranged in a stack with a face of each disc in contact with a face of the next adjacent disc in the stack. The contacting faces of the discs include surface formations defining small filtering passageways between adjacent discs for filtering a fluid passing between them. The surface formations include a rib array of spaced rib sections integrally formed on a flat surface of one of the contacting faces; and a protrusion array of spaced, discrete protrusions spacing the rib array of the one contacting face from a flat surface of the other contacting face.
Claims20
A multiple disc filter comprising:
- a plurality of discs arranged in a stack with a face of each disc in contact with a face of the next adjacent disc in the stack;
- the contacting faces of the discs including surface formations defining small filtering passageways between the contacting faces of adjacent discs for filtering a fluid passing between said contacting faces;
- said surface formations including:
- a rib array of spaced rib sections integrally formed on a flat surface of one of said contacting faces;
- and a protrusion array of discrete, small, spot protrusions spacing said rib array of said one contacting face from a flat surface of said other contacting face.
A multiple disc filter, comprising:
- a plurality of discs arranged in a stack with a face of each disc in contact with a face of the next adjacent disc in the stack;
- the contacting faces of the discs including surface formations defining small filtering passageways between the contacting faces for filtering a fluid passing between said contacting faces;
- at least some of said discs being of insulating material and including electrodes mutually-insulated from each other by the insulating material of said discs;
- alternating electrodes being connected to a first terminal for connection to one side of a voltage source, and the remaining alternating electrodes being connected to a second terminal for connection to the opposite side of the voltage source;
- each of said electrodes being of planar configuration and being formed with a plurality of closely-spaced gaps bridged by adjacent discs of insulating material and producing gradient electrical fields at the gaps.
