ION EXCHANGE: A FEASIBLE TREATMENT OF WATER THE OPPOSITE OF MEMBRANES!

Five centuries ago the method of ion exchange by the use of charged resins was one of the methods which are used in the water industry for the treatment of water. The method of ion exchange involves the removing of excess salts in the water. For example, arsenic, calcium etc. Sodium can also be involved in it.

In 1980s the membranes were used in the process of reverse osmosis were formation of favored method but lX is never disappeared. IX is obtained from a method of regeneration that is based on chemicals. The positive and negatively charged resins are used in this process.

One of the main advantages of lX and the process of absorption in during reverse osmosis in the still areas is the waste volume of the water that is produced. For every amount of the water that is treated by reverse osmosis from almost 10 percent to 50 percent of the water amount is being rejected as a concentrated stream of brine.

Only the used chemical and some of the rinsed water are wasted which is normally only from 2 percent to 4 percent.

The testing of the waste stream for the use with the local environmental protection needs can be achieved but in every situation the owner of mine recognized that having the range of silent approach to environment was the only way that can be used.

In Australia and New Zealand the quality of water was improved by the implementation of these processes in the water plants in order to clean them from all kind of side effects.

The recent water industry is practicing to focus on the technologies related to membranes which cover a large amount of the desalination in the market.

Today the two major problems that are challenge for the Australian industry. This system is becoming quite popular is the present time for the cleaning of the waste water.
