Ultrasonic energy is transmitted to sewage, including, inter alia, liquid or waste water, organic solid matter and aerobic bacteria, to reduce the liquid particle size and enrobe the reduced water particles with air to enhance the air to liquid absorption of the liquid and thereby provide (a) the aerobic bacteria with additional oxygen to utilize in the process of oxidation whereby the aerobic bacteria convert the organic solid matter to a more stable form or compound; (b) the effluent of sewage treatment plants with a higher oxygen content sufficient to aid or sustain desirable aquatic life. In a further embodiment, the liquid is first coverted to a thin film and then subjected to ultrasonic energy. In a still further embodiment, the sewage is first preheated to enhance the aerobic organism or bacteria activity. n In a still further embodiment the air is preheated and/or hydrated to diminish heat loss and thus a temperature drop, by the liquid. n Additionally, the synergistic effects of ultrasonic energy and ultraviolet energy are utilized to sensitize microorganisms which may then be easily destroyed by chemicals, and/or radiati on and/or other means. n Still further, the synergistic effects of ultrasonic and microwave energy are utilized to decontaminate the surface of sewage liquid and solids, the ultrasonic energy is utilized to produce a humid atmosphere and the microwave energy provides surface decontamination. |
