The RainDance "Tannin Eater" Well Water Tannin Removal System

Why You Should Consider A RainDance Twin Tannin Filter: First, what are tannins? Tannins (humic acid) are found in waters which have passed through large quantities of decaying vegetation. Tannins can cause yellow water and yellow staining on fabrics and fixtures. Tannins measuring at the low level of 0.5ppm can be problematic as tannins dissolve permanently into the water and won’t settle out over time. This can create a bad taste and odor in the water and cause staining to washing, toilet bowls, bath tubs and wash basins and cause poor filtration performance in water treatment systems.

The Twin Tank Tannin Eater provides an uninterrupted continuous supply of soft tannin free well water to your home or business. These systems feature two tanks for treating high tannins and hard water. Water is softened and tannins filtered in one tank while the other is in a standby mode. When the removal capacity of the first tank is reached, the system automatically switches tanks. The first tank is then recharged. This cycle is repeated when the second tank reaches its capacity point.

Why Is My Water Yellow And How Does RainDance Remove Tannins From Well Water: In the ion exchange process, well water containing tannins is passed through a modified RainDance Tannin Eater water softener. This special softener contains a resin that is manufactured solely for the purpose of removing tannin in the water. As they are removed they are replaced (exchanged) with chloride. The source of chloride is from the salt used to regenerate the unit which can be either traditional softener salt - sodium CHLORIDE or a special salt (no-sodium) called potassium CHLORIDE. Rather than waste either the sodium or the potassium we place the special tannin resin on top of regular softening resin and along with removing the tannins we also soften the water with the same amount of salt being used. We get a free bonus of softening.

Of particular importance is the proper selection of the tannin removal resin. It is specially formulated to cling tightly to the tannins a until regeneration is required and not let them release into the water in excess amounts --- a process called "dumping". As long as the equipment is functioning, safety is virtually guaranteed. A meter control on the Tannin Eater is very important to insure that regeneration is done even when unexpected excess water use occurs.
