Patent number: 8231786Abstract: Water treatment method and apparatus according to which supply water containing dissolved matter is delivered to at least one treatment surface. An electric field is created in the vicinity of the treatment surface to cause a hydration layer to be established due to the bipolar nature of the water molecules. Water is then extracted from the hydration layer. Such extraction may be effected by osmosis or by removal of the element (s) from the supply water with the hydration layer water thereon, dehydration layer water subsequently being extracted from the element (s). The method has been devised to reduce energy consumption for the purpose of providing potable water from seawater.Type: GrantFiled: October 12, 2006Date of Patent: July 31, 2012Assignee: HydroPath Holdings LimitedInventor: Daniel Stefanini

Patent number: 8168059Abstract: A method for inhibiting corrosion in at least one required region of an elongate metal structure, comprising applying a high-frequency electromagnetic signal to the structure in a manner such that a voltage standing wave is established in the structure with a corrosion-inhibiting potential at the required region(s) of the structure. The method is advantageously applied to an oil well riser pipe, to inhibit corrosion of the external surface thereof in the vicinity of an oil production zone.Type: GrantFiled: February 29, 2008Date of Patent: May 1, 2012Assignee: Hydropath Holdings LimitedInventor: Daniel Stefanini
