  • Patent number: 6096219
    Abstract: The present invention provides a method for the pre-treatment of hazardous biological and chemical contaminants from a waste fluid stream prior to discharge to a waste water treatment facility such as a publicly owned water treatment works or a similar privately operated facility. The method includes breaking apart tissue samples with a macerator, contacting a waste fluid stream with ozone, preferably in a vibrational mixer, which thereby acts as a promoter of hydroxyl radicals, passing the mixture through strong and weak unpolarized magnetic fields, static discharge and neutralization units, and finally, exposing the mixture to ultraviolet radiation. If found necessary, a subsequent static discharge and neutralization unit may be employed.

  • Patent number: 5811014
    Abstract: A process for treating flowable waste material to sanitize contaminants in the material includes the steps of neutralizing the charges of the molecules of the contaminants in the flowable waste material, for causing the molecules to separate from each other to increase treatment efficiency; exposing the flowable waste material to ozone; exposing the flowable waste material to electron beam radiation; exposing the flowable waste material to ultraviolet radiation; and exposing the flowable waste material to an ozone destructor mechanism. An apparatus is provided for treating and sanitizing flowable waste material containing contaminants, including an allotropic cell having a low density polyethylene sleeve removably secured over the tube outer surface for collecting material deposited onto the tube from the flowable waste material so that the deposited material is removable together with the sleeve.
