How Does Sodium metabisulfite Work In Water Treatment?
Sodium metabisulfite is commonly used in water treatment for several purposes. China Sodium metabisulfite has the following functions and applications in water treatment: Dechlorination: Sodium metabisulfite is often used to remove excess chlorine and chloramines from water. Chlorine is commonly added to municipal water supplies for disinfection, but an excess of chlorine can be harmful. Sodium metabisulfite reacts with chlorine to form harmless chloride ions and sulfur dioxide. Oxygen Scavenger: In some water treatment processes, sodium metabisulfite is used as an oxygen scavenger. It reacts with dissolved oxygen in water, helping to reduce the oxygen content. This is particularly important in systems where the presence of oxygen can lead to corrosion of metal pipes and equipment. Reducing Agent: Sodium metabisulfite acts as a reducing agent, which means it can reduce the oxidation state of certain substances in water. This property is useful in preventing the oxidation of sensi
