Removing Tannin With the Pulsar Disrupter Filter[caption id="attachment_6130" align="alignleft" width="164"] Tannin Removal Softener[/caption] A few months ago, I talked with a customer who wanted to buy a "tannin water softener." Well, it's really not a water softener - it looks like a water softener, but instead of Cation Exchange Resin like a water softener uses, it utilizes Anion Exchange Resin that is designed to trap tannin. In case you don't know, tannin is what give tea its' color. Tannin exists in small pockets in numerous places across the country and is simply caused by decaying vegetation which gives the water a unique yellow or brown color. The discoloration can run from mild to very dark. In this case, the customer said that it was very dark brown. Here's what I always advise:
However, as I mentioned, in most cases the Pulsar Disrupter will solve the tannin problem by itself. The tannin removal softener has to be after a good, high-efficiency Cation-Exchange Water Softener because the Anion- [caption id="attachment_6122" align="alignright" width="164"] Pulsar Disrupter Filter[/caption] Exchange Tannin Resin cannot tolerate hardness. It also has to regenerate every other day and it uses a good amount of salt. In other words, unless you just have to use it, you really don't want to. Sometimes it is just necessary to use a tannin softener if there is no other way of doing it, but don't just assume that immediately. However, I was not sure if the Pulsar would work as the customer said that their water was really, really bad. Weeks went by and I received this e-mail:
Start with the Pulsar Disrupter Filter. It is a unique filter with a "zeta charge". That simply means that it has the ability to attract and retain particles like tannin (plus a lot of other things) which effectively removes it from the water supply. It works in well over 90% of the cases and the filter has to be changed generally every six months to one year. If it doesn't work, then you simply have to add the "Tannin Removal Softener" and utilize the Pulsar as a "polisher."
Hello: Have to admit we were a bit skeptical but figured we had nothing to lose, so we decided to try the US Water Pulsar Disruptor Filter System and we are now tannin free! Couldn't be happier! Thank you so much! I've attached our before and after shots of our test run. Photos are not retouched. Sincerely, Chris S
