The method used usually relies on the absorption of Mg2+ and Ca2+ ions contained in water. The process used is to bind these ions to a molecule to eliminate the ability of these ions to form scale or scale or interfere with the performance of the detergent. This removal can be achieved through precipitation and ion exchange methods with options like Metered Immediate Mode.
Several ways that can be done to remove water hardness are by using reverse osmosis and distillation. However, distillation itself is very expensive for most cases of hard water, for that it applies more to the distillation process using water softener with cation resin. But some things must be known when we use a water softener, namely the maintenance process that must be routine. As for how to operate the unit of the water softener, namely:
Where in the process, water is filtered and then filtered from the top to the bottom through the exchange of ion cations. In the process, the unit on the softener filter can bind some levels of lime in the water content.
In this process, there is a process of washing a filter media, which is clogged or clogged with dirt in the filter media thereby reducing the flow of water that has been generated. For this reason, a backwashing method is needed.
Usually, the backwashing process itself needs to be carried out about every 3-6 days depending on the quality of the existing source water, in addition, if the condition of the water discharge decreases or decreases, a backwashing process is also required. That way, backwashing must be done continuously so that the condition and quality of the water are good. This backwashing process must be carried out until the output water in the effluent looks smooth and clean, it takes approximately 30 minutes for this process.
The regeneration process is the activation process of the cation resin media and pure NaCl salt media that are flowed. The trick is to prepare table salt or pure NaCl for about 20% then dissolve it in water using a special tube then the regeneration process can be carried out.
Fast Rinse Process
Is the final process of backwashing or regeneration. To do this process usually takes about 15-30 minutes until the wastewater runs smoothly. And usually, a rinsing process so that the remaining salt in the water can be removed completely.
