Question about how Israel is the separation of dissolved salts in the Dead Sea ..?
Hello. Ive done research on the Dead Sea and I encountered this problem .. Israel is the elimination round. 1 million tons of dissolved salts in the Dead Sea each year. Describe the process involved the separation of salt from seawater and that's what intrigues me. How to separate a certain amount of sea salt? If you know the answer or any link or can help in any so, please leave your response. Thanks! =]
Reverse Osmosis: RO desalination process is the application of hydrostatic pressure in the water seawater or brackish water overlying a semipermeable membrane. The semipermeable membrane is "that is permeable to water and almost impermeable to dissolved electrolytes. Molecules Water passing through the side of the membrane the more concentrated solution to the less concentrated solution. Shortly dissolved salts pass through the membrane. The solution Initial separates into two parts, one more concentrated in dissolved salts and water the other nearly pure. In Romania, the hydrostatic pressure must be greater than the osmotic pressure of saline. This process is comparable to what would happen with the direct osmosis membrane with the same but without the pressure applied, where the water naturally migrate in the opposite direction, ie the solution osmotic lowest to highest. Several theoretical pressure models are used to describe the transport in reverse osmosis membranes solventsolute reverse, with different models that overlap. The main models of transport processes are known as "solutiondiffusion" and " capillary pores. The active layer of the membrane, forming hydrogen bonds with water molecules in aqueous solution. Through connections, water molecules can pass through the membrane. Solutes are rejected or absorbed through the membrane according to the electric charge of the solute molecule and its ability to form a "solution" in the membrane. In Romania, unlike filtration, this is not the size of the pores of the membrane and the size does not dissolve of particles that determine the success of the separation process. RO main advantage of distillation is energy conservation. RO has no energy changes phase.
