Industrial water systems, particularly steam boilers and closed-loop cooling systems, are highly susceptible to corrosion caused by dissolved oxygen. Anhydrous sodium sulfite (CAS 7757-83-7) is a widely recognized and effective oxygen scavenger for these applications. When introduced into water, it readily reacts with dissolved oxygen, converting it into harmless sodium sulfate. This reaction, represented by the equation Na₂SO₃ + ½ O₂ → Na₂SO₄, effectively removes the corrosive agent, thereby protecting metal components from pitting and thinning. The use of anhydrous sodium sulfite is crucial for extending the lifespan of critical equipment, reducing maintenance costs, and ensuring the efficient operation of industrial processes. Its reliability and effectiveness make it a preferred choice for water treatment professionals. NINGBO INNO PHARMCHEM CO.,LTD. is a leading provider of high-purity anhydrous sodium sulfite, specifically graded for water treatment applications.
