Tannin Removal Resins
 | Tannin resin is often mixed with softening resin which reduces the amount of space required by the equipment and reduces the cost of the system. This type of design has performed satisfactorily in many areas. However during the regeneration the salt will displace calcium from the cation resin and potentially alkalinity from the anion/tannin resin which can promote calcium carbonate precipitation. It can be seen as a white precipitate in the resin bed and a coating on the drain line. Pressure drop through the system or a milky-white substance in the backwash water are indicators of precipitation.
It is best practice to run Tannin resins in a separate water softener that follows a traditional water softener. How Much Media do you need? |
