Abstract

A device and method for purifying waste water and stormwater flows by passage through a filter, which can be manufactured in various configurations. The filter has a broad range of thickness ranging from 1 mm to 20 meters. The filter is comprised of fibers from a melt of composition of 50% silicon dioxide, 15% aluminum oxide, 15% calcium oxide, 10% magnesium oxide, and other various oxides at lower percentages. At least the majority of fibers having a mean diameter of 4 microns and a mean length of 3 mm. The fiber solids of content of the material are at most 35% of the volume at a flow rate greater than 1 inch per hour to remove various pollutants from the water flow.

Claims (21)

1. A water treatment device, comprising:

a filter material of a thickness from 1 mm to 20 meters composed of fibers from a melt of silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, and one or more other types of oxides,

wherein the fibers of the device have a diameter of 1 to 40 microns and a length of 1 to 20 mm;

wherein a surface of the filter material is coated with aluminum oxide;

wherein the filter material has a positive charge, and

wherein the filter material is formed into at least one of blocks, sheets or granules used for treatment of wastewater or stormwater; and

a porous matrix support material disposed on an effluent side of the filter material, wherein the porous matrix support material includes a series of horizontal and vertical holes through which an effluent passes, and wherein the porous matrix is configured to allow for both perpendicular and parallel discharge of effluent.

2. The device of claim 1 , wherein the fibers comprise 5 to 35% of the volume of the filter material and the open space which accommodates water or air flow comprises 65 to 95% of the volume.

3. The device of claim 1 , wherein the fibers are coated with thermosetting phenolic resin which has been urea extended.

4. The device of claim 1 , wherein a mechanism is employed to increase the surface area.

5. The device of claim 4 , wherein the mechanism to increase the surface area is done by machining channels into the device.

6. The device of claim 4 , wherein the mechanism to increase the surface area is done by machining holes of various depths into the surface of the filtration media.

7. The device of claim 1 , wherein the water treatment device is part of at least one of a stormwater treatment system and a stormwater drainage infrastructure.

8. A filtering system, comprising:

filtration media having a positive charge and comprised of fibers from a melt of oxides bonded together with phenolic resin shaped into at least one of blocks and sheets, the filtration media including an influent side and effluent side;

a porous protective covering device of material placed on the influent side of the filtration media; and

a porous matrix support material on the effluent side of the blocks or sheets, wherein the porous matrix support material includes a series of horizontal and vertical holes through which an effluent passes, and wherein the porous matrix is configured to allow for both perpendicular and parallel discharge of effluent.

9. The system of claim 8 , wherein the blocks or sheets of bonded fibers include at least one of internal, vertical, angled and horizontal perforated material which acts as a discharge mechanism for water which has been treated by the filtration media.

10. The system of claim 8 , wherein the filtration media includes a height from 1 inch to 20 feet.

11. The system of claim 8 , wherein a water treatment device is part of at least one of a stormwater treatment system and a stormwater drainage infrastructure.

12. The system of claim 8 , wherein a surface of the filtration media is coated with aluminum oxide.
