Abstract

The present invention pertains to an effective system and method for reducing or eliminating the formation of scale in desalination systems. The system utilizes at least one pair of electrodes in direct contact with a liquid to induce an oscillating electric field directly in a portion of the liquid or a liquid stream of the desalination system. The electric field is capable of inducing bulk precipitation of ions, minerals, salts, particulates, contaminants or a combination thereof from the liquid stream.
