It is a type of boiler corrosion, caused by using highly alkaline water in the boiler. In boiler water, it contains a small amount of sodium Carbonate. In high pressure, it decomposes to give sodium hydroxide. Na CO +H O--- 2NaOH+CO 2 3 2 2 o Then this NaOH
Chapter 06 - Filtration. Filtration is used in addition to regular coagulation and sedimentation for removal of solids from surface water or wastewater. This prepares the water for use as potable, boiler, or cooling make-up. Wastewater filtration helps users meet more stringent effluent discharge permit requirements.

Boiler Water Treatment Guidelines; Columbia Boiler Co - Columbia Boiler Co - Low Pressure, High Pressure Boilers
The alkalinity of boiler water should be sufficiently high enough to protect shell and plates against acidic corrosion, but not high enough to produce carryover. A minimum value for alkalinity for adequate protection is 200 PPM. High boiler alkalinity, which is in excess of 700 PPM, should be avoided. Values higher than this can lead to
