Tannins removal
Tannins removal
(OP)
Hi I have a problem with the water of a shalow well near sea
I believe that tannins are the root of the problem but i can't hardly find decent info on the removal of this phenomenon
other caracteristicts from the water are that the conductivity is higher than normal(930 mS)the PH is low (6.05) and Iron 0.43 mg/L
the water looks like weak tea and has a bit of an oddor.
can somebody explane me posible solutions to get at least the color right
thanks in advace

The recommendation as to the most practical treatment scheme will depend on your application and flow.
Small volume applications such as homeowners have successfully used ion exchange resin to remove tannins.

To ensure that you select the optimum treatment scheme, obtain a comprehensive water analysis.

will have to study a bit what would be the best solution for my case
just one more question to ch81pc I'm not familiar with the term GAC what does it mean?

Ion exchange could help, you may need a pilot to confirm. Membrane filtration will work for sure.

I did try a alum treatment on the water with no result (it looks still like a cheap under aged wiskey)
The last resort option/advise to the customer would be to drill a deep well and hope that there is no arcinic in that water.
it's to be expected that I give an advise by next month so I can still try some stuf on the water samples I have
