The Importance of Tannic Acid (Tannins):

Tannic Acid (Tannins) is a by-product of subterranean decayed vegetation. Tannins (clear yellow colored water similar to urine) can cause yellowish stains on fixtures, clothing, washers, virtually anything the water contacts. It can also leave a residue in the piping, and the stains/residue are similar but not exactly like iron. Tannic acid can appear in color from slightly yellow to dark tan/brown.

What is Organic Iron?

Organic iron (not to be confused with iron bacteria) is the combination of tannins + iron. Organic iron is removed when the tannins are removed. Organic iron can pass through most filter media and cartridge filters, even when oxidized. Therefore, the removal of tannins is paramount in order to achieve complete iron removal.

Typically, the organic iron level will be 50%-100% of the tannin level. Therefore, it’s critical to have an accurate tannin ppm value.

What is used to eliminate Tannins?

Tannins can be removed using our special color removal media: Tannin Resin (TR). The TR is practically permanent. The TR can be used when oxidized iron is present. The TR removal media is a salt-based regeneration similar to a water softener.

Almost always TR can be placed inside a standard water softener resin tank. There are occasions when combining the 2 resins is not recommended. In this case, the GAC4 cartridge filter is used with complete success.
