Ion exchange resin is a great cost-effective way of softening hard water because it is unable to create lather using soap in hard water. The soap will be wasted while trying to make lather. As a result, it can result in a scum formation. It is possible to have hard water treated to lessen the impact of scaling and allow it to be used to wash and bathe.
A water softener is based on the concept of ion exchange or cation that involves the exchange of ions from hard minerals exchanged for potassium or sodium particles, which reduces the hardness mineral concentration to acceptable levels. You can buy ion exchange resins at wholesale prices in Australia.
One of the most affordable methods of softening household water is to use an Ion Exchange water softener. It uses table salt (sodium chloride) to replenish beads that are made of Ion Exchange resin which converts hardness mineral ions into sodium Ions. When the hard water passes through and around the beads, the hardness ions are absorbed and displace sodium ions. This process is known as ion exchange.
If the bead or sodium zeolite has a lower amount of sodium ions remaining in it, it ceases to be efficient and is in a position to not soften water. But, if the resin is replenished by the flushing (often flushing back) with salt water, it can be reused. The excessive concentration of sodium ions alters the equilibrium of the ions in solution as well as the ions that are held on the material's surface which results in being replaced by the mineral ions responsible for the hardness of the resin by sodium ions.
