How to deal with low pH value in water cut during electrodesalination
Thread Content
In our equipment, when the raw materials being processed are relatively light in density (such as Lula, Oman, etc.), the pH value of the water produced by electrodesalination is low, usually below 6, and sometimes even lower. Has anyone encountered this situation? How should it be adjusted? After all, the specified range for the pH of the wastewater discharged is 6–9. Additionally, could such a low pH value cause corrosion to the electrodesalination system?
Yes, Lula 870-880 is more or less that
I think since the raw materials cannot be changed, we need to consider other options; use electrodesalination for water injection, employ sulfur-treated purified water in one shift, check the quality of the purified water obtained through acid water stripping, and increase the amount of alkali added if necessary
