Abstract

An apparatus, system, and method relating to a modular water treatment apparatus that utilizes sidestream injection coupled to static mixing are described. The apparatus, system, and method utilizes ozone, with or without hydrogen peroxide, for effective disinfection and/or decontamination of contaminants present in waste water. The disinfected, decontaminated water is suitable for reuse.

Claims

1. An apparatus for removing contaminant from influent water, the apparatus comprising:

a plurality of modules assembled into a water treatment reactor, the plurality of modules including;

a main reactor comprising a diverter module, a first and second sidestream injector module, and at least one mixer module;

a first sidestream comprising at least one injector module connected to a source of a first oxidant comprising ozone and a static mixer module, wherein the injector module is upstream of the mixer module;

a second sidestream comprising at least one injector module connected to a source of a second oxidant comprising peroxide and a static mixer module, where the injector module is upstream of the mixer module;

the diverter module fluidly connecting the main reactor and the first and second sidestreams, the diverter module effective to divert a portion of said influent water to the first and the second sidestream;

the first sidestream injector module connected to the first sidestream for injecting influent water that is premixed with the first oxidant in said first sidestream;

the second sidestream injector module connected to the second sidestream for injecting influent water that is premixed with the second oxidant in said second sidestream,

at least one of the mixer modules comprising a static mixing component, and

wherein the diverter module is attached upstream of the sidestream injector modules,

the main reactor mixer module is attached downstream of the sidestream injector modules, and

the sidestream injector modules and the main reactor mixer module are further adapted with fittings effective to allow the optional assembly of additional injector modules and additional mixer modules into the apparatus in a single-pass, plug flow configuration.

2. The apparatus of claim 1, wherein the first oxidant is ozone.

3. The apparatus of claim 1, wherein said hydrogen peroxide is premixed with a second portion of the influent water in said second sidestream.

4. The apparatus of claim 1, wherein the at least one mixer module of the main reactor comprises at least two mixer modules, a first mixer module attached downstream of the first injector module and a second mixer module attached downstream of the second injector module.

5. The apparatus of claim 1, wherein the second injector module is located upstream of the first injector module.

6. The apparatus of claim 1, wherein the second injector module is located downstream of the first injector module.

7. The apparatus of claim 1, wherein the static mixing component is selected from a mixing component comprising a vane and a mixing component comprising one or more tabs.

8. The apparatus of claim 1, the second sidestream further comprising a pre-mix module upstream of the injector and mixing modules.

9. The apparatus of claim 8, wherein the pre-mix module is connected to a source of hydrogen peroxide.

10. The apparatus of claim 1, at least one of the first or second sidestream further comprising a post-mix module downstream of the injector and mixing modules.

11. The apparatus of claim 1, wherein said injector module and said mixer module of the first sidestream or the injector module and said mixer module of the second sidestream share a common housing.

12. The apparatus of claim 1, at least one of the first or second sidestream comprising a plurality of injector modules and a plurality of mixer modules in an alternating arrangement.

13. The apparatus of claim 1, wherein each injector module includes at least one injector.

14. The apparatus of claim 1, wherein each injector module includes a plurality of injectors arranged to maximize the dissolution of the oxidant premixed in the sidestream.

15. A sidestream-containing apparatus for removing a contaminant from influent water, the apparatus comprising:

a first plurality of modules assembled into a main reactor in the apparatus, the first plurality of modules comprising;

a diverter module effective to divert a portion of said influent water to a first sidestream and a second sidestream;

a first sidestream injector module connected to said first sidestream for injecting influent water from the first sidestream into the main reactor,

a second sidestream injector module downstream of the diverter module and connected to said second sidestream for injecting influent water from the second sidestream into the main reactor,

at least one mixer module comprising a static mixing component,

a second plurality of modules assembled into said first sidestream, the second plurality of modules comprising;

at least one injector module connected to a source of a first oxidant comprising ozone,

at least one mixer module comprising a static mixing component, and

conduits effective to introduce oxidant premixed with influent water in said first sidestream into the first sidestream injector module of said main reactor, and

a third plurality of modules assembled into said second sidestream, the third plurality of modules comprising;

at least one injector module connected to a source of a second oxidant comprising peroxide,

at least one mixer module comprising a static mixing component, and

conduits effective to introduce oxidant premixed with influent water in said second sidestream into the second sidestream injector module of said main reactor,

wherein said modules are adapted with fittings effective to allow the installation of additional optional injector modules and/or mixer modules to the first sidestream, the second sidestream, and/or the main reactor.
