It is one of the oldest methods of water softening. The process involves the addition of lime water in the hard water. One of the primary purposes of the lime water is to soften the water as well as remove any getting rid of any bacteria that may be in the water. The hard water is converted to soft water by a method known as precipitation. Precipitation is the reaction that occurs when a liquid turns into solid form. After the whole process is complete, some residuals remain and for proper maintenance of the environment, they should be discarded correctly.
Advantages of Lime Softening
Hard water is separated from the bacteria and other microorganisms.
It is pocket-friendly. The amount of money used to, but the materials and equipment to be employed in the process are not expensive compared to other water softening methods.
It assists in converting hard water to soft water.
The soft water is less erosive to the skin.
The chemicals used in the process are easy to handle.
Disadvantages of Lime Softening
The process requires a very high level of keenness.
The residuals used in the process are harmful if released into the environment.
Lime softening is a very viable way of water softening because when it is added to the hard water, it dissolves all the minerals in the hard water. The process decreases the acidity that is associated with the minerals in the hard water. Despite all the benefits of lime softening there are also some adverse effects. After the whole process is complete, there is a residual that remains. The components of the residual include the limewater itself and magnesium hydroxide. Unless disposed of carefully, the residual may flow into the rivers or the soil thus affecting its acidity and therefore, causing great harm to the society.
