The membrane helps to remove contaminate impurities using reverse osmosis

What is reverse osmosis?  Reverse osmosis is the process of purifying the water that removes larger particles from the water using a semi permeable membrane. This process is able to remove molecules, ions, bacteria’s in the drinking water, which is used for industrial purpose and domestic purpose.  In reverse osmosis, the pressure is applied to overcome the osmotic pressure.  The semi permeable membrane stops or blocks the waste particles in the water and finally, results in pure water.

The above diagram will make you understand the working of the reverse osmosis process clearly. From the above diagram 1 indicates the water enters the tube with a lot of impurities and bacteria. The 2 indicates the water impurities are blocked by the semi permeable membrane. The 3 indicates pressure inside the system will force the water molecules to enter the membrane. Finally pure water which is free of impurities and bacteria are allowed to pass on the next side of the membrane indicated by 4. The waste materials are then allowed to pass out of the system indicated by number 5 to the drainage or sink area. Finally the solute is present on the pressurized area of the membrane and pure solvent on the other side of the membrane. The reverse osmosis techniques are mostly commonly implemented in the purified drinking water from the sea water, which removes salt, solute, ions and other microbes from water molecules.

Components used in reverse osmosis 

The membrane in the reverse osmosis has a very tight pore structure that removes 99% of contaminate impurities from the water. The structure of the pore is 500,000 times less than the hair of the human. These pores have the capacity to remove dissolved solids, Bacteria’s, viruses and some chemicals. The reverse osmosis technology with antimicrobial filters is able to remove or block the bad odors, taste and colors from the drinking water. All over the world the reverse osmosis technology is used by all the water plants. The advantages of reverse osmosis technology are that ease of maintenance and a single touch of button will provide pure water. The home reverse osmosis system is costly compared to other domestic water filters.

What is reverse osmosis basic working of components? The components employed in the reverse osmosis art explained. In the above diagram the cold water line valve is attached to the inlet of the pre filter, where it is the source of water. The cold water enters the pre filter section, there may be more than one pre filter, these are used to filter the dirt, sand and impurities present in the water. Pre filters are sediment filters. The carbon filters are also used to remove the chlorine content from the water but this type of filters are not used when the reverse osmosis system ( membrane)  has cellulose triacetate. The most commonly used membrane is thin film composite material. The post filters are used to remove the remaining waste from water after the membrane filter. The automatic shut valve will automatically shut off when the storage tank is full. The check valve prevents water from backflow. The storage tanks keep the water pressurized, when the tank is full. The faucet line is usually connected to the end of the kitchen tap and drain is connected to the sink to remove impurities.
