In general terms, water treatment is just purifying available water of any source using various methods such as softening, de-mineralizing, reverse osmosis. In the case of softening, the hard minerals like calcium, magnesium and also some metals cat ions will be removed from the hot water this mainly helps to increase the compatibility with soap or detergent. And also that it extends lifetime of the conducive and the plumbing.
Water softening can be achieved using Ion-exchange resins.
Demineralization is very useful in certain field such as pharmaceuticals, leather, food processing units. Since the undesirable minerals are not to be in the water, the removal of the particular minerals called demineralization. Using the various filtration, and finally Ion exchanging methods has been a successful way in this system of purification.
Reverse osmosis has been very popular among all other purifying method given its uncomplicated method of purification. This membrane technology is not completely filtration systems. Generally osmosis process the fluid moves from an area of low dissolved concentration through membrane to an area of high dissolved concentrations.
Reverse osmosis is mainly used for drinking water purpose. Since the membrane pores are smaller than the nano technology, it completely stops even micro bacterium in this process. The largest and the most important application of the reverse osmosis is the separation of the pure water from drinking water.
This process is best known for its use in the desalination. And that it has also been used in the medical and industrial applications.
