Advantages and Disadvantages of Water Softening

Advantages of water Softening are:

Water Softening will deal with the problems caused by hard water such as excessive soap use and scaling.
Depending on the type of water softening process used, softening may also aid in other water treatment processes.
water Softening often removes iron and manganese, reduces tastes and odors, reduces total solids content, and removes radioactivity.
The high pH associated with lime softening can aid in disinfection.
When water is stabilized using recarbonation at the end of the lime water softening process, corrosion in the distribution system is avoided.

Disadvantages of Softening are:

Water Softening processes are expensive.
The high pH associated with lime softening tends to form hypo chlorate as the dominant free chlorine residual, which is less powerful disinfectant than other free chlorine residuals.
The high pH may also increase tri halomethane levels in the water.
If the water is not properly stabilized after treatment, then corrosive water may be produced which will corrode the distribution system.
Ion exchange water softening, can also cause problems due to the high levels of sodium in the treated water.
Both lime softening and ion exchange softening create waste disposal problems.
