Boron Treatment in Drinking Water

Published on by in Social

Curious to know of the different methods for Boron removal from potable water. We are attempting to remove Boron coming out of a well that is intended to be used on agricultural pastures. 

Tests show Boron levels coming in at 2.3 ppm and at .004 ppm for arsenic.

Also wondering if anyone has heard of using humic acid to mitigate boron and arsenic uptake in plants?

Thank you. 
 

one update:

after more thorough water testing we see high levels of sodium and chloride, which apparently go hand in hand with boron.

  2. Hi Gerasimos,

    the most common technologies to remove boron is likely to be RO and IX. 

    From your update, you mentioned that sodium and chlorides need to be removed as well. This will tilt the balance towards selection of RO. 

    You need not indicate the size of the treatment system or the % of removal of the boron concentration desired. These information would be required to make an assessment which technologies is more cost effective.

  3. Boron can be due to watewater contamination as it is used in industrial soaps. There is no unexpensive solution to get rid of Boron, RO is probably the most advisable solution.

  4. If you would like to have the BORON made "Inert" and have NO ELECTRICAL Charge we can use Electro-Oxidation technology (not electro-coagulation).  Making Boron and other Heavy Metals Inert by this process will make the particles go from a TDS state to a particle of less than 1/2 micron size, be inert and will not reform.  Other minerals are affected the same and organics are also reduced to 1/2 micron size.  Disinfectant of organics, H2S, algae, etc. is done because the process creates 45 families of oxidants and 400+ reactions.  

  5. According to my experience, best way is to increase PH before Reverse Osmosis to 10. Normally in the second pass of the RO. on this way you dont have precipitation problems of other salts.

  8. I  have  more  experience  with  water  monitoring  than water  treatment . But  what  I  notice  that  ion  exchenge  membranes  is  the  method  of  choice  in  a  such  cases. About  arsenic  ,  humm  it  dont  sounds very  good. One  should  consider other  choices  of   water  supply  if  available and compare  costs  and  practicity between  treat  this  water and to  find  other  water  source. Best  regards

  9. Reverse Osmosis or Cationic/anionic Resins are reliable methods. Never heard about humid acid to remove boron. Anyway boron limit for drinking water was 2,4 mg/l (2009). I have heard that a is too much for citric fruits cultives irrigation (affects quality of the orange taste)  but not for pastures. 
    There are Modern RO membranes that are selective for boron removal.
