What is the purpose of reverse osmosis in boiler feedwater treatment?

The purpose of reverse osmosis in boiler feedwater treatment is to remove dissolved solids and impurities. This process is crucial as it helps maintain the quality of the water fed into the boiler. By using a semipermeable membrane, reverse osmosis effectively separates water from a wide range of contaminants, including dissolved minerals, metals, and organic compounds.

This removal of dissolved solids is vital because high levels of impurities can lead to scaling, corrosion, and other issues that negatively impact boiler operation and efficiency. By ensuring that the feedwater is as pure as possible, reverse osmosis contributes to improved longevity and performance of the boiler system.

Other options do not capture the fundamental function of reverse osmosis in boiler feedwater treatment, since it is specifically tailored for purifying water rather than enhancing color, increasing pH levels, or reducing water usage.
