Treating boiler water after it has entered the boiler
Internal boiler water treatment
Chemical used in a water treatment test to indicate the presense of a specific substance
Reagant
A chemical that combines with oxygen to form harmless compounds for removal from the boiler
Oxygen scavenger chemicals
The ability of a material to pass electrons
Conductivity
A scale that represents the pH level from 0 to 14 based on whether a solution is acidic, alkaline or neutral
pH scale
A collection of muddy mineral sediment that can be discharged while suspended in boiler water
Nonadhering sludge
The mineral group that includes silicates of aluminum, sodium, and calcium used to soften water
Zeolite
A condition where exposure to highly alkaline elements cause boiler metal corrosion at stress zones in the boiler

Sodium sulfite
A water treatment accessory that introduces water treatment chemicals in a loop on the discharge side of the feedwater pump
Bypass feeder
A substance found in sand and some water that can form scale
Silica
Water that contains small quantities of dissolved minerals
Soft water
The property of a solution determined by measuring its pH level
Alkalinity
A water treatment test using a reagant to determine the concentration of a specific dissolved substance
