reverse osmosis drinking water

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..

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..

Rain is the main source of water. A part of the rain water seeps into the ground, to form ground water, some of it evaporates back into the atmosphere and some of it flows to form streams and rivers which flow ultimately into the sea. In rural areas open wells and bore..

In the absorption of water by plants Cell to cell movement of water occurs throughout the plant body The rigidity of plant organs is maintained Leaves become turgid and expand due to osmotic pressure Growing points of root remain turgid and penetrate the soil parti..

Most of the reactions are reversible in nature. In these reactions both the forward and the backward reactions occur simultaneously. For e.g., in the following reaction, the forward reaction is exothermic; but the backward reaction is endothermic: But both the reactions occur. This m..

Introduction - Apart from air, the most abundant substance on the earth is water. Humans need water for drinking, bathing, sanitation, washing, cooking etc. Modern agriculture, industry, transport, power generation, civic facilities etc., cannot exist without wate..

About 70-73% of earth is covered by water. Water is available in the form of oceans, seas, rivers, lakes, ponds, pools, polar ice caps and water vapour. The main component of hydrosphere is water. Water exists in all the three forms i.e., solid (sno..
