NEUTRALIZATION CALCULATION pH neutralization calculation

Calculation of required gas injection amount when adding carbon dioxide gas to alkaline wastewater to neutralize to pH7

Input

Raw water flow（m3/h）
Raw water pH
Margin ※1
Chemical name
carbon dioxide gas

Result

Chemical injection amount(kg/h)
Gas injection amount(Nl/min)

The result of this calculation is just a reference value and does not guarantee the pros and cons of neutralization.

*1 Margin
In the actual neutralization reaction, it is rarely neutralized according to theory because of the formation of salts between the neutralizing chemicals and the components contained in the water. Therefore, the calculation result multiplied by the margin is used as a guide for the injection amount. (Margin: about 3 to 10 times)
