What is permutit process?
what is calgon’s process?
what is ion exchange process?
Answers
Answer:
Permutit process is a process in where hard water containing such as ca++ is filtered through a natural sand called the zeolite.
Calgon ionizes to give a complex anion: The addition of Calgon to hard water causes the calcium and magnesium ions of hard water to displace sodium ions from the anion of Calgon. This results in the removal of calcium and magnesium ions from hard water in the form of a complex with Calgon.
Ion exchange is an exchange of ions between two electrolytes or between an electrolyte solution and a complex. In most cases the term is used to denote the processes of purification, separation, and decontamination of aqueous and other ion-containing solutions with solid polymeric or mineralic "ion exchangers".
Explanation:
Permutit process is a process in where hard water containing such as ca++ is filtered through a natural sand called the zeolite.
Calgon is a trade name of a complex salt, sodium hexametaphosphate. (NaPO3)6.
The addition of Calgon to hard water causes the calcium and magnesium ions of hard water to displace sodium ions from the anion of Calgon.
The exchange process occurs between a solid (resin or a zeolite) and a liquid (water).
In the exchange of cations during water treatment, positively charged ions that come into contact with the ion exchange resin are exchanged with positively charged ions available on the resin surface, usually sodium.
