Question

In comparison to the zeolite process for the removal of permanent hardness, the synthetic resins method is:

• A. more efficient as it can exchange only cations
• B. more efficient as it can exchange both cations as well as anions
• C. less efficient as it exchanges only anions
• D. less efficient as the resins cannot be regenerated

Answer 1

The correct option is B more efficient as it can exchange both cations as well as anions

Synthetic resins method have the exchange capability 3 times higher than zeolite process and former can exchange both cations and anions in the hard water.
