Abstract
A materials treatment system which includes filtration and treatment of solid and liquid components of a material, such as a waste material. A filter or substrate assembly is provided which allows liquids to pass therethrough, while retaining solids. The solids are then incinerated utilizing microwave energy, and the liquids can be treated after passing through the filter element, for example, utilizing a treatment liquid such as an oxidant liquid. The filter assembly can also include an exhaust filter assembly which removes solids or particulate matter from exhaust gasses, with the retained solids/particulates incinerated utilizing microwave energy.
Claims34
A treatment system comprising:
- means for removing solids from a stream to produce a stream of clarified liquid;
- a microwave filter assembly having an inlet receiving said stream of clarified liquid, said microwave filter assembly further including a filter element for removing and retaining suspended particles from said stream of clarified liquid and allowing filtered liquid of said stream of clarified liquid to pass through said filter element, and wherein said filter element includes a ceramic material, said microwave filter assembly further including microwave means for incinerating the suspended particles removed and retained by said filter element with microwaves;
- and
- means for mixing said filtered liquid passing through said filter element with at least one oxidant, said means for mixing disposed downstream of said microwave filter assembly such that said at least one oxidant is mixed with said filtered liquid after said filtered liquid passes through said filter assembly.
A treatment system comprising:
- means for removing solids from a stream to produce a stream of clarified liquid;
- a microwave filter assembly having an inlet receiving said stream of clarified liquid, said microwave filter assembly including:
- (a) a housing defining a cavity therein;
- (b) a filter element disposed in said cavity for removing and retaining suspended particles from said stream of clarified liquid and allowing filtered liquid of said stream of clarified liquid to pass through said filter element;
- (c) a screen disposed below said filter element and inside of said cavity, said screen delimiting a microwave chamber within said cavity;
- and
- (d) microwave means for incinerating the suspended particles removed and retained by said filter element with microwaves, said microwave means introducing microwave energy into said cavity at a location above said filter element, and wherein said microwave means introduces microwave energy through an aperture in said housing.
A treatment system comprising:
- means for removing solids from a stream to produce a stream of clarified liquid;
- a microwave filter assembly having an inlet receiving a said stream of clarified liquid, said microwave filter assembly further including a filter element for removing and retaining suspended particles from said stream of clarified liquid and allowing filtered liquid of said stream of clarified liquid to pass through said filter element, and wherein said microwave filter assembly further includes microwave means for incinerating the suspended particles removed and retained by said filter element to with microwaves;
- means for introducing at least one oxidant into the filtered liquid passing through said filter element, said means for introducing disposed downstream of said microwave filter assembly and introducing said at least one oxidant into the filtered liquid after exiting said microwave filter assembly;
- and
- means for subjecting the filtered liquid to at least one of ultraviolet radiation and microwave radiation at a location downstream of said microwave filter assembly.
