FORM-2 THE PATENTS ACT. 1970 (39 of 1970) COMPLETE SPECIFICATION (Section 10, rule 13) A SYSTEM AND METHOD FOR DESALINATION Ms. Kaiser Irani residing at 1 Spenta Society, Old Khandala Road, Khandala, Maharashtra 410302, India An Indian National THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED FIELD OF INVENTION This invention relates to desalination systems. In particular this invention relates to water desalination systems. Further, this invention relates to a system and method of desalination using magnetic nanoparticles. BACKGROUND Desalination process is removal of salt and minerals from water (water desalination) or soil (soil desalination). Conversion of such water to fresh water has become a necessity for providing potable water (drinking water). There are many factors which lead to water scarcity. Global warming leading to seasonal disturbance is a major cause. A country like India has taken initiative to formulate a solution for this problem of providing potable water. Various methods, systems and devices are in use and many more to come in. Some of the conventional desalination systems utilize filtration and distillation processes. Drawbacks includes one of more like poor recovery, cost and labor intensive, high energy utilization, sophistication in design or technique requiring technical expertise adding to the cost, space barrier, and similar kind. Additionally, discharge water (with high salt / contaminant) of existing systems (distillation, Reverse Osmosis, Forward Osmosis) contaminating environment due to lack of correct disposal measures that are either not practiced, not available or not being taken care of. Further limitations of the currently used systems are fouling and / or salt deposition that limits the life of membranes. Desalinization exists today in a very inefficient way. Large amounts of water have to go into vats of containment and sit there while heat is used in various ways. There are various systems, some of them steam, some of them not, all requiring heat to take out the salt. It takes a long time. It is expensive and not efficient. Therefore it is not tenable to desalinate for an entire city. Instead, only places that simply have no fresh water at all have a system like this. It becomes a necessity of inconvenience and expense instead of a good solution. This patent provides for desalination system and methods using nanotechnology wherein desalination in domestic, medical, to industrial purposes uses magnetic nano particles / magnetic robots / magnebots (for water purification / desalination purposes other than liquids, gases and air) and envisage reduction in operation and cost. For example, carbon nanotubes in nano structured material substantially destroys, modifies, removes, or separates contaminants in fluid that comes into contact with said material; engineered or tailor made molecules, engineered PEG based hydrophilic magnetic nano particles (MNP) capable of drawing solutes in FO; and membrane device based on Ion concentration Polarization (ICP) concept for separates salts and microbes desalinizing water electrostatically. Nanotechnology offers solution to desalination or removal of contamination from sea water. Research and development in the area of desalination using functionalized magnetic nanoparticles is discussed. Some of the illustrative examples include use of magnetic nanoparticles functionalized with selective synthetic salt ion-receptors to extract dissolved salt ion from saline water; Zero-valent iron with the mobility and reactivity of iron nanoparticles for groundwater remediation and Magnetic "nanorust" for decontaminating Arsenic from drinking water. Such methods overcome drawbacks of conventional desalination methods including membrane based in reducing cost, energy, electricity and components replacement and waste disposal problem. This system and method desalinizes water without contaminating the environment or by using fossil fuels in cost effective manner.

DETAILED DESCRIPTION OF THE ACCOMPANYING DRAWINGS According to this invention, there is provided a desalination system adapted to receive saline water in order to desalinate it to obtain desalinated potable water, Figure 1 illustrates a schematic diagram of desalination system. In accordance with an embodiment of this invention, there is provided a partitioned tank (1) adapted to receive saline water in one portion of the tank. In accordance with another embodiment of this invention, there is provided an entry means adapted to allow entry of magnetized nanotechnology robots (nanobots) (3) in said saline water. They are assigned to find the dissolved salts (2) and attach themselves to them, Typically, this activity takes place in a first portion (4) of said tank. Thus, all of the salt then becomes magnetic, with tiny little nano robots hanging onto all of it. In accordance with another embodiment of this invention, there is provided a magnet or an electro magnet adapted to pull the magnetized salt in one direction, preferably to the bottom of the tank. In accordance with yet another embodiment of this invention, there is provided an exit means (5) adapted to allow exit of said magnetized salts. No heat is involved. Preferably, a tank has to be build with a strong magnet at the right bottom of the tank to pull out all the magnetized particles. In accordance with still another embodiment of this invention, there is provided a second portion (6) of the tank (I) where desalinated water overflows from said first portion for use. The water never has to rest and never has to be cooked. There is no heat involved at all. Using nano-technology, the water goes in one end of the machine, and it comes out the other in a steady flow. The flow maintained is In (flow) of salty water and out (flow) of fresh water, and which is ready then for standard purification. The first stages of the system requires that there is substantial or optimum release of nano-technology robots assigned to find the dissolved salts and attach themselves to them. Every single robot is magnetized. All of the salt then becomes magnetic, with tiny little nano-robots hanging on to all of it. On to the next stage: Flowing into the next area, the water is exposed to tremendous, huge electromagnets, pulling the salt out of the water completely and totally, because the salt is now magnetic. Thus, no heat is involved. The advantages of the present invention include: No support medium required. Useful for domestic purpose and is also scalable. Efficient, cost effective and simple. Space is not a constraint. There is no heat involved, the water is not cooked. The water that comes out is ready for normal purification and thus obtained water is magnetized water having health benefits. I claim, 1.
