After driving, the alkalinity is low while the salt content is high

Thread Content

Why is the alkalinity low and the salt content high after each drive, and what measures should be taken to avoid this?

I hadn’t noticed this issue; it’s normal to take samples after the vehicle is driving stably and normally.

It may be that the low alkali concentration causes the membrane’s carboxylic acid layer to expand, reducing its ability to block Cl-

What is the quality of the brine after parking and then starting the vehicle again? Is there any analysis of the chlorate content in saltwater?

Is what the poster is saying that after each start-up of the ion exchange membrane electrolyzer, the alkali solution has a low concentration and a high salt content? This is a normal phenomenon, as concentration gradient diffusion after parking leads to an increase in the salt content in the alkali. This phenomenon cannot be resolved; the substandard alkali produced initially can be used for waste gas absorption, brine purification, and wastewater treatment, etc. Once the concentration and salt content at the electrolyzer outlet meet the required standards, it can then be fed into the tank containing the finished alkali.

The ineffective contraction of the membrane results in a higher porosity, which in turn leads to a higher salt content; therefore, the tank temperature should be increased appropriately
