Abstract: A liquid desalination system is disclosed. The liquid desalination system includes a feed line having an inlet to receive liquid and an outlet to discharge the liquid. The liquid desalination system includes a magnet coupled to the feed line, the magnet to generate an oscillating magnetic field within the feed line and in opposition to the feed water flow. The removal of targeted ions can be achieved by manipulating the frequency and rate of the generated electromagnetic waves. The generated electromagnetic waves can be tuned to weaken the hydration bonds of that specific ion and facilitate its removal. The liquid desalination system generates an electric field across the feed line to enable the liquid to flow through the electric field. The electric field may attract sodium ions to a positive electrode and may attract chloride ions to a negative electrode, to desalinate the liquid in the feed line.
