The RainDance "Tannin Eater" Catalog & Selection Guide

 


When Tannins are present, they will cause a yellow to dark tea color in water and an unpleasant taste and odor. This effect is caused by humic and fulvic organic acids formed during the decomposition of vegetation. Tannins occur in water in almost any location where large quantities of vegetation have decayed. The structure of tannins depends on the vegetation in the area and varies from location to location. Tannin molecules tend to form anions in water above pH 6 and can be treated with anion exchange resins. Below pH 5 tannins are better treated with activated carbon. RainDance Water Systems offers a number of different capacities of Tannin Removal Filter Systems 

The RainDance Tannin Eater combines the functions of a water softener (Removing water hardness and clear water iron) with a tannin filter removes Humic and Fulvic acids (large molecular weight organics which impart a brown/yellow tint to water and improves flavors and odors  ).

Whole house tannin Filters can accommodate well water pump flow rates from 10gpm up to 100gpm and can be installed on 3/4" up to 2" plumbing lines.
