By this technique sewage water can he converted into fairly clean drinking water..

Reverse Osmosis and Water Purification - 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 desalinat..

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..

The gases containing dust are passed through a porous medium. which is usually woven fabrics. The particles present in the gas are trapped and collected in the filters. The gases freed from the particles are then discharged. A Typical Bag Filter..
