Abstract
An apparatus and method are provided. The method includes for example, treating a liquid in an apparatus to increase suspension properties of the liquid and dispensing the treated liquid from the apparatus to a surface or volume of space so as to create an electrically conductive path by the treated liquid from the apparatus to the surface or volume of space. During the step of dispensing, an alternating electric field is generated from the apparatus to the surface or volume of space, through the liquid along the conductive path, wherein the electric field is sufficient to destroy at least one microorganism from the surface or in the volume of space.
Claims30
An apparatus comprising:
- a container configured to engage a liquid and at least one compound configured to increase suspension properties of the liquid to provide a treated liquid;
- a liquid flow path coupled to the container;
- a liquid dispenser coupled in the liquid flow path, adapted to dispense the treated liquid to a surface or volume of space;
- an electrode electrically coupled to the liquid flow path;
- and
- a control circuit adapted to generate an alternating electric field between the electrode and the surface or volume of space, through the dispensed treated liquid, without a corresponding return electrode.
A method comprising:
- treating a liquid in an apparatus to increase suspension properties of the liquid;
- dispensing the treated liquid from the apparatus to a surface or volume of space so as to create an electrically conductive path by the treated liquid from the apparatus to the surface or volume of space;
- and
- during the step of dispensing, generating an alternating electric field from the apparatus to the surface or volume of space, through the liquid along the conductive path, wherein the electric field is sufficient to destroy at least one microorganism from the surface or in the volume of space.
A method comprising:
- treating a liquid in an apparatus to alter an oxidation reduction potential of the liquid;
- dispensing the treated liquid from the apparatus to a surface or volume of space so as to create an electrically conductive path by the treated liquid from the apparatus to the surface or volume of space;
- and
- during the step of dispensing, generating an alternating electric field from the apparatus to the surface or volume of space, through the liquid along the conductive path, wherein the electric field is sufficient to destroy at least one microorganism from the surface or in the volume of space.
