reverse osmosis water purification systems

The osmosis process can actually be reversed if a pressure larger than the osmotic pressure be applied to the solution. This phenomenon has found uses in water purification, especially the desalination of sea water..

Osmosis in a cell can be demonstrated by a potato osmoscope experiment. Peel the skin of a potato and remove the inner contents to form a cup shaped hollow. Place the potato in a container with water. Pour 5% sugar solution in to the potato cup up to a particular level. Pierce ..

Equilibrium Involving Chemical Systems - In reversible reactions chemical reactions take place in both the forward and backward directions. For example, the reaction between gaseous hydrogen and iodine vapours to give gaseous hydrogen iodide is a reversible reaction an..

Producer gas is passed into the regenerator G 1 which has been heated previously. Air is passed through another regenerator G 2 which is also heated. Producer gas burns in air over the hearth of the furnace producing large amount of heat, which is used to melt the charge. The combustio..

Apart from the salts which flow down to the sea waters due to weathering of the rocks, a variety of sources, such as land and sea volcanic activity, seismic activity, deposit large amounts of minerals and metals in the ocean. Some of these dissolve in the water and may rest at t..

In lower organisms, there is no transport system as the cells are in touch with the surrounding medium. The transport is by the physical processes like diffusion, osmosis, etc. With the advancement in structure, the organisms have to evolve methods to transport nutrients an..

Surface chemistry is the study of processes that occur at the interface of two bulk phases. The bulk phases can be of the type solid-gas, solid-liquid, liquid-gas and liquid-liquid. There is no interface between gases because of their complete miscibility. The bulk phase can be solutions or pure co..
