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.
Claims24
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 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.
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 reactive filtration mechanism 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;
- 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.
A method comprising:
- supplying an influent water stream containing a contaminant to a membrane filtration mechanism operable to separate at least a first portion of the contaminant from a resulting first effluent water stream;
- directing the first effluent water stream to a reactive filtration mechanism operable to remove a waste stream containing a second portion of the contaminant from a resultant second effluent stream;
- and,
- recycling at least a portion of the waste stream from the reactive filtration process back to a point upstream of the membrane filtration mechanism.
A method comprising:
- supplying metal salt reagents to a moving media filter in the presence of contaminated water;
- and,
- introducing a waste stream produced by the moving media filter upstream of a membrane filtration mechanism.
