sea water reverse osmosis

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..

Elements in Sea - 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 d..

It is a physical process in which the solvent (water) moves from the region of its higher concentration to the region of its lower concentration across a semi-permeable membrane. This is to say that water moves from a dilute to a concentrated solution. Water is absorbe..

It is a process involving net diffusion of water molecules from a region of higher water concentration to a region of lower water concentration through a semipermeable membrane. The osmotic movement of water from a surrounding medium into a cell is called end..

A thistle funnel, covered at the broad end by a differentially permeable membrane, contains a 10% sugar solution. The beaker contains a 5% sugar solution as shown in fig. a. The solute is unable to pass through the membrane, but the water passes freely through in both directions. The net..

Peel off the skin of a large sized potato with a scalpel. Cut its one end to make the base flat. Make a hollow cavity in the potato almost up to the bottom. Add sugar solution into the cavity and mark the level by inserting a pin in the wall of the cavity of the tuber. Place the po..

Consider a sample of an ideal gas kept in an enclosure. The state of the gas is described by specifying its pressure P, volume V and temperature T. If these parameters can be uniquely specified at a time, we say that the gas is in thermodynamic equilibrium. If we put the enclosure on a hot stove, t..

Tides are caused due the gravitational pull of the moon on the water in oceans and seas. The enormous movement of water between the high tides and low tides provides a very large source of energy in the coastal areas of the worl..
