Regenerant

Definition - What does Regenerant mean?

Regenerant is a chemical compound solution that is used in the restoration of ion exchange system capacity. For instance, sodium chloride brine can be classified as a regenerant and is utilized in water softener ion exchange.

Regenerant solutions are very helpful in analyzing the effects of metal corrosion as well as pollution, especially in boiler thermal systems.

Corrosionpedia explains Regenerant

Regeneration is the process of restoring a medium for ion exchange into something that is usable post-exhaustion. It involves the introduction of backwash regenerant as well as fresh water rinse, which are required to ready the exchange bed water softener for service.

In regeneration, a certain regenerant solution is used and made to pass through the exchange bed composed of acids and based deionizers and salt brine softeners. The brine is used as the regenerant itself while the acids and bases as regenerants for anion and cation resins utilized in the process of demineralization.

By using regenerants, water can soften, which can neutralize the alkali from decomposing sodium salt that may be present in boiler systems. This results in reduced alkalinity within the boiler, which in turn prevents the likelihood of alkaline corrosion. Also, this prevents caustic embrittlement in metals, which could contribute to the reduced discharge of pollution in boilers.

With the aid of regenerants, the resin in the water can be prevented from being polluted, increasing the yield of water in the equipment for water treatment. With such, there can be reduced corrosion and pollution of water in the industries, especially in boiler systems.
