pH Treatment Introduction. Acidic and basic (alkaline) are two extremes that describe chemicals just like hot and cold are two... Boiler pH. Natural water is usually between 6.5 and 7.5 pH. A common recommendation is to maintain boiler water at 8.5... Controlling

Boiler Water Treatment | Sensors for Process Control ...

pH Control pH plays a vital role in boiler water control. A slightly alkaline pH must be maintained to prevent corrosion. The alkalinity helps maintain a passivation layer which protects the boiler from corrosion. The typical pH levels maintained in different parts of the boiler are included in the table below.
