BENEFITS OF A TANNIN FILTRATION SYSTEM
Tannins can cause yellow-brown discoloration and a musty smell in your drinking water. Don’t compromise on your water quality because you have a private well – with Pentair on your side, you can keep tannins in check. Tannins can often go hand-in-hand with high iron content. If your water contains high iron levels, couple your Whole House Tannin Filtration System with a Whole House Iron Reduction System for the best results. Other features include:
- Automatically regenerates only when necessary, using less salt, saving time and money
- Self-cleaning design keeps the system running smoothly with little maintenance
- Simple, electronic system for easy programming; maintains settings during power outages
HOW IT WORKS
Filtration
Your water passes through the mineral tank, and the tannin elements get trapped in the negatively-charged anion resin. The brine tank holds a solution of water and salt that replaces these ions with sodium.
Backwashing
During backwashing, the water treatment system reduces the dirt and tannins from the mineral tank and washed down the drain.
Regeneration
The mineral tank is recharged with sodium from the brine tank solution and displaces calcium and magnesium, which is flushed down the drain during the backwashing phase.
Rinse
The mineral tank is rinsed with fresh water and loads the brine tank so that it is ready for the next cycle.
Controller
Recharging cycles are controlled by the electronic meter on the top of the tank. This can be set to recharge every specified number of days or as the electronic head recognizes that a certain amount of water has been used.
