There was an error in the original publication [1].

The chemical reaction in Equation (3) is not balanced.

Equation (3) has been updated from “In the tank: NaOH + Cl₂ → NaOCl + NaCl + H₂O” to “In the tank: 2NaOH + Cl₂ → NaOCl + NaCl + H₂O”.

There is an error in Equation (6): The power consumption on the left is given in an energy unit, kWh (W should have been capitalized), while on the right side the product of current, voltage and time (which is energy) is divided by volume (V) given in liters (and thus has the unit of kWh/L).

Equation (6) has been updated from

Electric power consumption (kwh) = = \frac{I . t . U}{1000 V}

(6)

to

Electric power consumption (kWh / L) = \frac{I . t . U}{1000 V}
