Too low pH after RO
Too low pH after RO
(OP)
I live in the country where (primary)standard for pH for drinking water is 6,5 to 8,5. And there is no separate standard for "purified water". Tap water(municipal)pH is about 6,7. Standard residential RO system (sediment 5u, GAC, Carbon Block, TFC membrane, carbon postfilter) lower pH to 6,2 sometimes below 6. And that's against the law!
Is there any type of pre(or post) filter which can make RO permeate water pH > 6,5 (in standard) but keeping TDS low?
Thanks.
