A system and method for water purification by capture of contaminants in an aqueous mixture is described herein. A system and method for regenerating the capture system is also described. An integrated capture and regeneration system and method is also described including a separation vessel that houses a capture bed and an electrode in electrical contact with the bed and a power source for applying a voltage to the electrode. The applied voltage enhances capture of the contaminant from aqueous liquid on the capture bed and modulation of the applied voltage enhances release of contaminant on the capture bed into aqueous wash liquid to regenerate the bed. The aqueous wash liquid may contain a counter ion that binds to the contaminant forming an aggregate contaminant phase that separates from the aqueous wash liquid.

A magnet positioning system for positioning magnets inside pipes includes a first stackable paddle that includes slots for accepting magnets and a second stackable paddle that includes a metal component for attracting the magnets and securing the magnets in the slots when the paddles are stacked together. Once stacked together, the paddles are inserted into position inside a pipe and the metal component is removed to release the magnets which move toward, and attach to, the inside wall of the pipe. A fluid conduit is positioned between the magnets using a spacer and a fixing agent permanently secures the magnets, fluid conduit, and spacer in place.
