Abstract: The present invention provides a new method and apparatus/system for purifying ionic solutions, such as, for example, desalinating water, using engineered charged surfaces to sorb ions from such solutions. Surface charge is applied externally, and is synchronized with oscillatory fluid movements between substantially parallel charged plates. Ions are held in place during fluid movement in one direction (because they are held in the electrical double layer), and released for transport during fluid movement in the opposite direction by removing the applied electric field. In this way the ions, such as salt, are “ratcheted” across the charged surface from the feed side to the concentrate side. The process itself is very simple and involves only pumps, charged surfaces, and manifolds for fluid collection.

Abstract: The water is at the origin of an entire series of geological and climatic processes and is primarily the basis of all forms of life. Actually, it is the majority component of all living organisms (50% to 98%); the human body contains 70% of the total mass thereof. The biosphere in its entirety consists of 80% water. Although this may be one of the most highly examined liquids, its properties comprising numerous anomalies have not yet all been elucidated. It plays an essential role in the structure and metabolism of all living beings. This biological role is due to its physical and chemical properties that are out of the ordinary. Bernal and Flower established a rule defining that each oxygen atom has two hydrogen atoms as neighbors and each hydrogen bond contains one hydrogen atom. The separation of the liquid water molecules produces the formation of hydroxyl ion (OH?) and hydronium ions (H3O+), which hampers this rule.
