Bicarbonate Alkalinity
Bicarbonate Alkalinity
(OP)
I have a client who is drawing water from a local creek and the water is very high in bicarbonates. Is there a way to treat this water to be used for irrigation purposes on a racecourse?

RE: Bicarbonate Alkalinity
A H2SO4 dosage is recommended to obtain H2O and CO2 from raw water with high HCO3 content. After acid dosage a CO2 removal degassor will be a must to increase pH. After CO2 removal, if you are still having a low pH, try a neutralization NaOH dosing system.
HCO3- + H+ > H2O + CO2
H2SO4 > 2 H+ + SO4
I hope this will help but if you still need any asistance please do not hesitate to contact me.

P.S. I thought you can calculate the necessary dosage volume by the given equations.

Alkalinity is removed by either lime softening the water or using a low pressure RO membrane. Neither of these methods are probably going to be economical for you.
Do you have a complete water analysis? And why are you so concerned about the alkalinity?
