How to Regenerate Purigen

As it adsorbs waste products, Purigen will darken to dark brown, almost black. Once it is exhausted, it can be regenerated with a solution of bleach and water. The bleach will literally “burn off” the organics stuff on the surface of Purigen.

Difference - bleach vs brine regeneration

Some filter media products can be regenerable with a brine solution. However, brine regeneration only restores ion-exchange. A brine solution will not remove organics, and over time such filter media will be less effective at organic waste absorption. Whereas the bleach burns off even the hardened organic stuffs that remain on the surface of the Purigen filter media, totally restore Purigen to its effective state.
