What is the primary purpose of water treatment in boiler systems?

The primary purpose of water treatment in boiler systems is to control pH, hardness, and oxygen levels. Proper water treatment is essential for maintaining boiler efficiency and longevity.

Controlling pH is critical because if the water is too acidic or too alkaline, it can lead to corrosion in the boiler and piping systems. Hardness refers to the concentration of calcium and magnesium ions in the water, and managing these levels is important because hard water can lead to scale formation on the boiler heat exchange surfaces, negatively affecting heat transfer and overall efficiency.

Oxygen control is equally vital, as dissolved oxygen in water can contribute to pitting corrosion, especially in high-temperature environments like boilers. By treating the water to remove contaminants and maintain optimal chemical levels, the integrity of the system is preserved, reducing maintenance costs and improving operational safety.
