Abstract
Abstract 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. In a still further embodiment the air is preheated and/or hydrated to diminish heat loss and thus a temperature drop, by the liquid. 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. 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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
The process of sonobioaeration for treating sewage utilizing an electroacoustic horn, said sewage including liquid, solid organic matter and aerobic organisms comprising the steps of: exposing said electroacoustic horn to air; converting said sewage to a thin film; applying said thin film of sewage to the surface of said electroacoustic horn; and transmitting ultrasonic energy with said electroacoustic horn to said thin film of sewage, in the presence of said air, to atomize the thin film of sewage to reduce the particle size of said liquid and enrobe said reduced liquid particles with said air to provide said aerobic organisms with additional oxygen, derived from said air, for said aerobic organisms to utilize in the process of bio-chemical oxidation whereby said aerobic organisms convert said organic matter to a more stable compound.
Claim 2
Dependent Claim
132 words
The process of sonobioaeration for treating sewage utilizing an electroacoustic horn, said sewage including liquid, solid organic matter and aerobic organisms comprising the steps of: exposing said electroacoustic horn to air; converting said sewage to a thin film; applying said thin film of sewage to the surface of said electroacoustic horn; and transmitting ultrasonic energy with said electroacoustic horn to said thin film of sewage, in the presence of said air, to atomize the thin film of sewage to reduce the particle size of said liquid and enrobe said reduced liquid particles with said air to provide said aerobic organisms with additional oxygen, derived from said air, for said aerobic organisms to utilize in the process of bio-chemical oxidation whereby said aerobic organisms convert said organic matter to a more stable compound.
Claim 3
Dependent Claim
190 words
The process of sonobioaeration for treating sewage utilizing an electroacoustic horn, said sewage including liquid, solid organic matter and aerobic organisms, comprising: exposing said elecrtroacoustic horn to air, passing said sewage through a passageway formed internally, of said electroacoustic horn, impinging said sewage against an impinging member provided centrally of a spiral nozzle attached to said electroacoustic horn and aligned concentrically with said passageway disperse said sewage and to reduce the particle size of said liquid and to enrobe the reduced liquid particles with said air to enhance the air to liquid absorption of said liquid, collecting a predetermined portion of said dispersed sewage on the convolutions of said nozzle to form said sewage into a thin film; and transmitting ultrasonic energy in the presence of said air to said sewage in said thin firm form collected on said nozzle convolutions to further reduce the size of said liquid particles and to further enrobe said liquid particles of further reduced size with additional air, said additional air providing oxygen for said aerobic organisms to utilize in the bio-chemical oxidation process of converting said organic matter to a more stable compound.
Claim 4
Dependent Claim
190 words
The process of sonobioaeration for treating sewage utilizing an electroacoustic horn, said sewage including liquid, solid organic matter and aerobic organisms, comprising: exposing said elecrtroacoustic horn to air, passing said sewage through a passageway formed internally, of said electroacoustic horn, impinging said sewage against an impinging member provided centrally of a spiral nozzle attached to said electroacoustic horn and aligned concentrically with said passageway disperse said sewage and to reduce the particle size of said liquid and to enrobe the reduced liquid particles with said air to enhance the air to liquid absorption of said liquid, collecting a predetermined portion of said dispersed sewage on the convolutions of said nozzle to form said sewage into a thin film; and transmitting ultrasonic energy in the presence of said air to said sewage in said thin firm form collected on said nozzle convolutions to further reduce the size of said liquid particles and to further enrobe said liquid particles of further reduced size with additional air, said additional air providing oxygen for said aerobic organisms to utilize in the bio-chemical oxidation process of converting said organic matter to a more stable compound.
Claim 5
Dependent Claim

Claim 7
Dependent Claim
26 words
The process according to claim 2 wherein said ultrasonic energy is transmitted to said thin film at a frequency within the range from 20kHz to 30kHz.
Claim 8
Dependent Claim
44 words
The process according to claim 2 including the further step of pre-heating said enrobing air to a predetermined temperature to compensate for any heat loss in the process of reducing the particle size of said thin film in the presence of said enrobing air.
