It is unsuitable for turbid and acidic water
Huge amount of precipitate is formed which creates a disposal problem
The effluent cannot be reduced to zero hardness
It is unsuitable for softening the water of excessive hardness
Answer is Right!
Answer is Wrong!
The correct answer is: B. Huge amount of precipitate is formed which creates a disposal problem.
The lime soda process is a chemical water softening process that uses lime and soda ash to remove calcium and magnesium ions from water. The process is effective in removing hardness, but it does produce a large amount of precipitate, which can be difficult to dispose of.
The other options are incorrect because:
- A. The lime soda process can be used to treat turbid and acidic water.
- C. The effluent from the lime soda process can be reduced to zero hardness by using a second stage of treatment, such as reverse osmosis.
- D. The lime soda process can be used to soften water of excessive hardness.
In conclusion, the major disadvantage of the lime soda process of water softening is that it produces a large amount of precipitate, which can be difficult to dispose of.
