Abstract
The invention encompasses systems and methods for removing contaminants from an aqueous stream using systems and methods that add treatment agents comprising anchor particles and tethers, with optional activating agents or activators.
Claims24
A system for water treatment, comprising one or more systems selected from the group consisting of:
- a. a bacteria-removal substrate modifier system;
- b. a dissolved-metals removal substrate-modifier system;
- c. a suspended-solids removal substrate-modifier system;
- d. a hardness-removal system;
- e. an organic-removal or oil-removal substrate-modifier system;
- and
- f. an oxidizing agent technology system.
A system for removing an oxidizable contaminant from a fluid, comprising:
- an oxidizing agent, wherein adding the oxidizing agent to the oxidizable target contaminant forms an oxidized species that precipitates as an insoluble precipitate in the fluid;
- a substrate that forms a removable complex with the insoluble precipitate, thereby sequestering the oxidizable contaminant, and
- a removal system for removing the removable complex from the fluid.
A method for removing a dissolved contaminant from a fluid stream, comprising:
- converting the dissolved contaminant to an insoluble form;
- introducing an anchor particle into the fluid stream, wherein the anchor particle has an affinity for the insoluble form to form a removable complex therewith;
- and
- removing the removable complex from the fluid stream.
A method for removing a metal ion species from a fluid stream, where the metal ion species is a soluble metal ionic species, comprising:
- oxidizing the soluble metal ion species with an oxidizing agent to form an insoluble oxidized species;
- flocculating the insoluble oxidized species to form flocculated particulates;
- providing a substrate that has affinity for the flocculated particulates;
- introducing the substrate into the fluid stream to contact the flocculated particulates, whereby contacting the substrate with the flocculated particulates forms a removable complex;
- and
- removing the removable complex from the fluid stream, thereby removing the metal ion species.
