Abstract
Exemplary systems and techniques for treating contaminated water are described. In one instance a plant or system includes a membrane filtration mechanism operable to receive an influent water stream containing a contaminant and to separate at least a first portion of the contaminant from a resulting first effluent water stream. The system also includes a reactive filtration mechanism operable to receive the first effluent water stream and to remove a waste stream containing a second portion of the contaminant to produce a resultant second effluent stream.
Claims14
A system comprising:
- a membrane filtration mechanism operable to receive an influent water stream containing a contaminant and to separate at least a first portion of the contaminant from a resulting first effluent water stream;
- and,
- a continuously regenerating radial moving bed media filter comprising a filter media having a metal salt reagent positioned on a surface of the filter media and further operable to receive the first effluent water stream effective that a second portion of the contaminant adheres to the metal salt reagent positioned on the surface, and wherein the continuously regenerating radial moving bed media filter is configured to clean the metal salt reagent and the adhering second portion of the contaminant from the surface in a waste stream while the cleaned filter media is recycled to receive additional first effluent water to continuously produce a resultant second effluent stream.
A system comprising:
- a membrane filtration mechanism operable to receive an influent water stream containing a contaminant and to separate at least a first portion of the contaminant from a resulting first effluent water stream;
- a continually regenerating moving bed radial reactive filtration media filter comprising a filter media and operable to receive the first effluent water stream and to remove a waste stream containing a second portion of the contaminant from a resultant second effluent stream while cleaning and recycling the filter media;
- and,
- a mechanism operable to add metal salt reagents to the first effluent water stream sufficient to generate metal salt residuals in the waste stream and further comprising another mechanism operable to return at least a portion of the waste stream into the influent water upstream of the membrane filtration mechanism.
