Benefits

  • Use the high-quality Purolite TanEx anion exchange resin filter media.
  • Automatically uses salt water to clean and restore the resin media.
  • Salt is automatically added to the brine tank, similar to an automatic water softener
  • Leaves water free of color by removing a wide range of tannins and humic acids
  • Choose the 5900 Control Valve with the Bluetooth app for your phone or the ceramic disc type 7500 control valve for lower maintenance.

Frequently Asked Questions

Q. What guarantee is included with this system?
A. Unfortunately, we cannot offer a money-back guarantee for tannin or color in water, as water conditions and chemistry vary widely.  To make sure your tannin filter installation will be successful we request you send us 1 gallon of water so we can do testing here at our shop prior to purchasing a system.   Please contact our support team for instructions at [email protected]
 
Q. What are tannins?
A. Tannins are astringent, bitter-tasting plant polyphenols that bind and precipitate proteins.

Tannins in well waters form from humic acid, which is one of the major components of humic substances (or Natural Organic Matter (NOM).

These are the dark brown constituents of soil organic matter. They can also be found in peat, coal, many upland streams and ocean water.

The word tannin refers to the source of tannins used in tanning animal hides into leather; however, the term is widely applied to refer to brown color in water, caused by decaying organic substances.

Q. How can tannins be removed so my well water is clear?
A. Tannins can be removed by self-cleaning automatic tannin filters These filters remove tannin by ion-exchange, using anion exchange media.

Q. How do they work?
A. The units we use regenerate with rock salt (sodium chloride) in the same way water softeners function. Frequently, shallow wells, under the influence of surface run-off water, achieve high levels of tannins (turning the water brown) during heavy rainy periods.

Q. What type of resin is used inside the tannin filter?
A. We use Tanex by Purolite. Purolite Tanex is a proprietary blend of two high-performing anion exchange resins that produce outstanding tannin and organic color removal even in highly challenging applications.

Q. Can I mix Tanex resin in my regular water softener so it can remove color and soften water at the same time?
A. We don't recommend this. A water softener should be set up to regenerate (backwash and clean the resin) based on gallons used. However a tannin filter should be set ideally to regenerate every few days in order to avoid the tannins from fouling the tannin resin.

Q. How long does tannin resin last?
A. 1 to 5 years depending on water chemistry.
