pH Treatment | CleanBoiler.org - Boiler Consortium

When the boiler water pH drops below about 8.5, a corrosion called acid attack can occur. A low boilerwater pH is usually caused by contamination of the boiler feedwater, from sources such as hydrochloric or sulfuric acid from leaks in demineralizers and condenser leaks of cooling tower water. is often encountered in phosphate treated
