Sodium chlorate production

The pH value should be kept slightly acidic; a more alkaline environment reduces the current efficiency. In addition, it is necessary to strictly control the sodium chloride content in the electrolyte flowing out and the temperature of the reactor
Depending on the type of groove used, the current density ranges from 2000 to 3000 A/M2; the current density at the anode and the cathode is the same since their areas are equal； The pH of the electrolyte is controlled at 6.2–6.6
Our company operates in the same way, but I’m not sure about the relationship between current and flow efficiency
