Abstract
In a method of removing organic contaminants from a liquid, an oxidizing gas is formed into sub-micron size bubbles which are dispersed into an initially contaminated liquid, after which the treated liquid is recovered. The oxidizing gas is preferably selected from a group including ozone and chlorine dioxide and is utilized immediately upon its manufacture. An oxidizing liquid may be employed in conjunction with the oxidizing gas.
Claims20
A method of removing organic contaminants from liquids comprising the steps of:
- providing an oxidizing gas at least a portion of which is oxygen;
- forming the oxidizing gas into sub-micron size bubbles;
- providing a photocatalyst;
- providing a flow of initially contaminated liquid;
- dispersing the sub-micron size bubbles of oxidizing gas into the flowing initially contaminated liquid while simultaneously activating the photocatalyst;
- recovering the treated liquid.

A system, comprising:
- (a) a communication network capable of providing a first-type channel having a relatively low bandwidth and at least one second-type channel having a relatively high bandwidth over a communication line of the network;
- (b) a node of the network having an access ID server capable of generating in response to a request an access ID, wherein an access ID is required to be provided to a switching system of central office facility of the network in order to establish a circuit over the second-type channel;
- and
- (c) a calling node of the network that establishes a virtual that does not require an access ID with the access ID server using the first-type channel to request the access ID from the access ID server, wherein the access ID will enable a circuit to be established between the calling node and an end point of the network using the at least one second-type channel, wherein the calling node receives the access ID from the access ID server over the virtual circuit and establishes the circuit over at least one second-type channel by providing the access ID to the switching system.

- providing an oxidizing gas;
- forming the oxidizing gas into sub-micron size bubbles;
- providing a photocatalyst;
- providing a flow of initially contaminated wastewater;

4 more elements
An apparatus, comprising:
- (a) a means for coupling to a communication network capable of providing a first-type channel having a relatively low bandwidth and at least one second-type channel having a relatively high bandwidth over a communication line of the network, wherein an access ID is required to be provided by a calling node of the network to a switching means of the network in order to establish a circuit over a second-type channel;
- (b) means for receiving a request for an access ID from the calling node via a virtual circuit that does not require an access ID established by the calling node using the first-type channel, wherein the access ID will enable a circuit to be established between the calling node and an end point of the network using the at least one second-type channel;
- (c) means for generating the access ID in response to the request
- (d) means for transmitting the access ID to the calling node via the virtual circuit;
- and
- (e) the switching means for receiving the access ID from the calling node and for establishing the circuit between the calling node and the end point using the access ID.
