reverse osmosis water purification unit

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..

- This unit is an assembly of various parts like, a) Dust precipitator, which removes dust from the gases. b) Scrubber, which removes soluble impurities. c) Drying tower, which removes moisture from the gases. d) Arsenic purifier, which removes impurities of As 2 O 3..

Summary - Cell is the structural and functional unit of the organism. Water is the principal constituent of plants and is essential for the maintenance of life, growth and development. Plants absorb water from the soil through their roots, transport it to other parts o..

When the total number of moles of the products is greater than the total number of moles of the reactants (except for pure liquids, solids, and the solvent in excess). In such cases, the equilibrium constant has the unit (mol/L) where 'n' may be 1,2 ... etc. For example, for the..

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 dissolve in the water..

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 and wastes. ..

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..

>The proteins present in the membrane may function as carriers or receptors or enzymes. Transport across membranes involves several mechanisms. There are processes like diffusion and osmosis, which do not require energy or activity of the cell. Diffusion involves movement of molecules fro..
