Abstract
The present invention provides systems, methods and devices for removing contaminants from an aqueous stream. In embodiments, these systems and methods may be applied to particular applications, for example removal of contaminants in aqueous streams associated with the petroleum industry.
Claims27
System for removing contaminants from a waste stream, comprising two or more modules in fluid communication with the waste stream, each module comprising either:
- (a) an oxidizing agent;
- or (b) a filtration medium comprising a substrate for supporting a modifier compound, and a modifier compound attached thereto, wherein the modifier compound has an affinity for a contaminant in the waste stream, forming a complex with the contaminant and thereby removing it from the waste stream, wherein at least one module comprises a filtration medium.
A method of removing contaminants from a fluid stream, comprising:
- contacting the contaminants in the fluid stream with an oxidizing agent, thereby oxidizing the contaminants within the fluid stream, and
- removing the oxidized contaminants from the fluid stream.
A method for removing a contaminant in contaminated water, comprising contacting the contaminated water with a targeted sorbent having a specific affinity for the contaminant, wherein the targeted sorbent comprises a supportive substrate modified with one or more combinations of functional components.
A system for treating frac flowback water, comprising:
- a sequential treatment pathway comprising a plurality of treatment modules, the plurality of treatment modules comprising, in any order, at least two modules selected from the group consisting of a suspended-solid removal module, a bacteria-removal module, an oil-removal module, a metal-removal module, and a water-hardness treatment module.
A method for producing a water source for hydraulic fracturing, comprising:
- collecting surface water,
- treating the surface water using the system of claim 25 to yield treated surface water,
- collecting produced water,
- treating the produced water using the system of claim 26 to yield treated produced water, and
- combining the treated surface water and the treated produced water to provide the water source for hydraulic fracturing.
A device for removing a contaminant from a waste stream, comprising a filtration medium within a housing, said filtration medium comprising a substrate for supporting a modifier compound, and a modifier compound attached thereto, wherein the modifier compound has an affinity for a contaminant in the waste stream;
- wherein the housing is adapted for insertion into the waste stream.
