Magnetic field potency for separation techniques

Abstract: Pollution-free fresh water for industrial purposes is increasingly difficult to find. Groundwater availability is very limited. A very potential method to get pollution-free fresh water is done by desalination of sea water process. Numbers of seawater desalination technologies have been developed during the last several decades to augment the supply of water in arid regions of the world. However, the treatment process is quite complicated and costly. There is another potential method for converting seawater to fresh water in which continues stream of seawater dissolving ions is separated into desalted and concentration streams by using a magnetic field. Cations moving in a magnetic field from the top down will veer to the left; Anion will veer to the right, while the neutral particles will still move straight. This fundamental theory is estimated to have the potential to separate the electrolyte (salt) dissolved from the solution. To determine the possibility of applied basic theoretically, the two sources of the magnetic field, i.e. a toroidal magnet and an electromagnet (solenoidal), were composed. In the toroidal magnet, slits were made with 4 mm width. In the solenoidal magnet, distance (slits) of north and south magnetic pole was 5 mm. Through this slits, water which has small spot area and formed a sraight path (if no magnetic field)was spouted. Deflection of cations and anions will cause the water passage cross section turns into a line after going through a magnetic field. The fact observed in this experiment can conclude that the electromagnetic equipment to separate the dissolved electrolyte ions can be made. However, a further problem is increasing in the efficiency of the separation process. If the use of current electric can be economically lowered, then a device that can convert sea water into fresh water may be designed.
