I am a synthetic organic chemist by trade and find myself in a new position of carrying new products for an animal repellent company that incorporates predator animal urines in their products through the EPA registration process. The bacterial and viral protocols we have had developed through Cornell University School of Veterinary Medicine involve our company pasteurizing and filtering the animal urines. We hope to use through 5 and 0.2 um media to remove many bacteria and spores. I currently have limited equipment, other than gravity filtration materials, to attempt to carry this out. I have had difficulty even on the 25 um level with fluted papers. We will be facing the filtration of 5 to 55 gal lots in production and I need to filter a 1 gal lot for EPA testing ASAP. What route would you suggest I go and/or is there a filtering consultant who we could contract to perform the smaller filtration in the meantime? Any direction you can provide would be very much appreciated.
Have an insight or suggestion?

Re: Filtering technology
20 December 2006 at 1:29pmBacteria and spores are very difficult to filter, much like in beer. The only way I know to do this is to add filter aids such as DEs (like World Minerals Std. Super Cel or Celite 512) or Rice Hull Ash (made by Traclana,LLC in Houston and AgriLectric Co. in Lake Charles, La.).
