This method of water treatment is employed to meet following basic objectives: Provide protection against corrosion, scaling and foaming. Conditioning of sludge or any other suspended substance (like iron oxide) in the boiler system. Remove oxygen content from the boiler feed water and maintain sufficient alkalinity for fighting against corrosion.
Boiler water treatment - Lenntech
The boiler receives the feed water, which consists of varying proportion of recovered condensed water (return water) and fresh water, which has been purified in varying degrees (make up water). The make-up water is usually natural water either in its raw state, or treated by some process before use.

WATR 6016 2 INTRODUCTION Boiler feedwater can be treated after it enters the boiler. This is called internal treatment and it is achieved through the addition of chemicals to the feedwater. Boiler water testing is critical to the safe and efficient operation of a steam
UNIT-1 WATER AND ITS TREATMENT 1.6. Treatment of boiler feed water – Internal treatment (phosphate, colloidal, sodium aluminate and calgon conditioning) Softening (Conditioning) Methods Water used for industrial purposes should be free from
Use of polymers further aids in conditioning any suspended solid contamination that may have entered with the boiler feed water. Internal treatment for sulfates The boiler temperature makes the calcium and magnesium sulfates in the feedwater insoluble.
Carbonate conditioning: Reagent added is sodium carbonate. In low pressure boilers scale formation can be avoided by adding sodium carbonate to boiler water CaSO +Na 2 CO 3 CaCO 3↓+Na 2 SO 4 Sludge Deposition of CaSO as scale doesn't takes
Water treatment units are responsible for purifying and de-aerating make-up water or feed water. Conditioning is the essential adjunct to a treatment programme and includes the rational injection of «conditioning products» via dispensing units. phosphates: combined with the alkaline nature of boiler water, phosphates neutralize hardness by
