Abstract:
1. A method of water treatment to provide relatively-purified water from supply water containing dissolved matter, the method comprising the steps of: delivering the supply water to at least one treatment surface provided on at least one movable element movable relative to the supply water; creating an electric field at or in the vicinity of the at least one treatment surface to electrically charge the at least one treatment surface to cause a hydration layer of water molecules to be established in the supply water in the vicinity of the at least one treatment surface; partially withdrawing the at least one movable element from the supply water with the hydration layer on the at least one movable element; and extracting the hydration layer by electrically discharging the at least one treatment surface to release the hydration layer from the at least one movable element subsequent to the withdrawing step.
