Hi Muhammad,

I have learnt from my field experience that any formula in this case may only be a guide. I suggest you analyze for the Physicochemical and bacteriological parameters of the industrial water as first approach. The value of the residual chlorine ( if any) and other parameters will guide you in appropriate treatment to make the industrial water potable. You can try using an efficacy test approach, that is, using pilot trials to determine the amount of Chlorine or Sodium Hypochlorite that disinfects the industrial water to acceptable and permissible drinking water quality standards in your location and in accordance with WHO guidelines for drinking water.

The value or amount of Chlorine or Sodium Hypochlorite that gives you the efficacy could be used as your basis for chlorine or Sodium Hypochlorite dosage. You can set you disinfectant dosing pump to that value in relation to time and quantity of water being treated as a scale up from your pilot value and confirm the output (treated water for drinking by usual analysis).

Please note that using this method means that the quality and quantity of industrial water generated/treated must be constant, which in most cases are not. So you might need to be performing the pilot trials for each batch of industrial water generated, it might also contain other contaminants you have to remove by physical or chemical treatments. Converting industrial water to drinking water needs painstaking approach(es).
