Method of sterilizing liquids
Abstract
Abstract IMPROVED, ECONOMICAL METHOD FOR THE CONTINUOUS OR BATCH STERILIZATION OF BACTERIOLOGICALLY CONTAMINATED LIQUIDS AT INCREASED LIQUID FLOW RATES BY MEANS OF THE SYNERGISTIC EFFECTS PRODUCED DURING THE SIMULTANEOUS AND COMBINED ACTION OF ULTRAVIOLET FLUX AND HIGH INTENSITY ACCOUSTIC WAVES IN THE SONIC OR ULTRASONIC RANGE. THE METHOD INVOLVES THE USE OF ULTRAVIOLET IRRADIATION WITHIN THE 1800 A. TO 4500 A. REGION WITH INTENSITIES EQUAL TO AT LEAST 1 WATT PER SQUARE FOOT OF PROCESSED AREA IN AIR AND 16,000 MICRO-WATT SECONDS PER CM.2 IN LIQUIDS WHILE SIMULTANEOUSLY SUBJECTING THE LIQUID TO AN ACOUSTIC FIELD HAVING A FREQUENCY OF THE ORDER OF BETWEEN 5 AND 150 KHZ. AND AN AVERAGE ACOUSTIC ENERGY DENSITY LEVEL EQUAL AT LEAST TO 1 WATT PER LITER IN THE PROCESSING CHAMBER.
