Reverse Osmosis System
Reverse osmosis is the best known filtration method and it is widely used in pharmaceutical water systems. This process is used to remove the particles including ions from the water. Reverse osmosis system contain a semi-permeable membrane that allows to pass the water and rejects the contaminants. In most of the reverse osmosis system it cleans the membrane it self and the process is known as crossflow. Reverse osmosis is capable to remove the salts, sugars, proteins, dyes, bacteria and other particles having the molecular weight greater than 250 daltons even viruses. The reverse osmosis process requires a force to pass the water through the membrane known as driving force. This force is applied in the form of pressure with the help of high pressure pumps. Contaminates of water are separated and collected in a tank known as concentrate. Generally the RO system recovers70-80% of feed water and this efficiency decreaseas the membrane is used.The...
