WHAT IS CLAIMED:

1. A method of preparing a regenerated spent fermented beverage media that includes silica stabilization media, the method comprising heating a spent fermented beverage media in an oxidizing environment to form the regenerated spent fermented beverage media, wherein the spent fermented beverage media is in the form of spent cake or membrane retentate, wherein the regenerated spent fermented beverage media is suitable for re-use in stabilization and, optionally, filtration of fermented beverages.

2. The method of claim 1, further including:

dewatering the spent fermented beverage media by filtration or centrifugation; and drying the spent fermented beverage media prior to the heating for regeneration.

3. The method of claim 1, in which the heating is at a temperature of about 600 °C to about 800 °C.

4. The method of claim 1, wherein the oxidizing atmosphere is achieved by intimately

contacting the spent fermented beverage media being regenerated with air containing oxygen sufficient to fully oxidize organic matter in the spent fermented beverage media, the air ambient air or oxygen enriched air.

5. The method of claim 4, wherein the air as supplied contains 15% to 50% oxygen by volume.

6. The method of claim 1, wherein the heating occurs for a time period of 30 seconds to 1 hour.

7. The method of claim 1 further comprising adding an oxidizing agent to the spent fermented beverage media during the heating.

8. The method of claim 7, wherein the oxidizing agent is hydrogen peroxide, ozone, fluorine, chlorine, nitric acid, an alkali nitrate, peroxymonosulfuric acid, peroxydisulfuric acid, an alkali salt of peroxymonosulfuric acid, an alkali salt of peroxydisulfuric acid, an alkali salt of chlorite, alkali salt of chlorate, alkali salt of perchl orate or alkali salt of hypochlorite.

9. The method of claim 1, in which the heating is at a temperature range of about 650 °C to about 750 °C.

10. The method of claim 1, wherein the spent fermented beverage media further includes an inorganic material other than silica stabilization media.

11. The method of claim 10, wherein the inorganic material includes diatomite, perlite or rice hull ash.

12. The method of claim 1, further comprising adding new or regenerated stabilization media and optionally new or regenerated filtration media to the regenerated spent fermented beverage media to adjust the stabilization capability of the regenerated spent fermented beverage

media, the size exclusion of the regenerated spent fermented beverage media or the permeability of the regenerated spent fermented beverage media.

13. The method of claim 1, wherein the silica stabilization media includes silica xerogel, silica hydrogel, hydrated silica xerogel or silica hydrous gel.

14. The method of claim 1, wherein the spent fermented beverage media that is heated for regeneration is stabilizing-filtration media.

15. The method of claim 14, wherein the stabilizing-filtration media is modified diatomite stabilizing-filtration media or Celite Cynergy.

16. The method of claim 1, in which the spent fermented beverage media is dewatered by

filtration or centrifugation and dried prior to heating for regeneration.

17. The method claim 1, further including:

accumulating spent fermented beverage media; and

segregating, prior to the heating, the spent fermented beverage media according to permeability range, stabilization media content or extractable chemistry.

18. The method claim 17, further including storing the spent fermented beverage media prior to regeneration.

19. The method of claim 1 in which the heating to form regenerated media takes place within the same manufacturing location as the filtration process by which the spent fermented beverage media was produced.

20. The method of claim 1 in which the heating to form regenerated media takes place within a 100 mile radius of the location of the filtration process by which the spent fermented beverage media was produced.
