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.
