Abstract
Disclosed are methods of removing particulate matter from a wastewater stream, comprising providing an activating agent capable of being affixed to the particulate matter in the wastewater stream; affixing the activating agent to the particulate matter to form activated particles residing in the wastewater stream; processing the activated particles in a thickener device to produce a population of thickened flocs in the fluid stream, wherein the thickened flocs comprise the particulate matter; contacting the thickened flocs with a re-activating agent to form re-activated particles comprising the particulate matter; providing a population of tether-bearing anchor particles, wherein the tether-bearing anchor particles have an affinity for the re-activated particles; attaching the tether-bearing anchor particles to the re-activated particles to form removable complexes that comprise the particulate matter, and removing the removable complexes, thereby removing the particulate matter from the wastewater stream.
