SMBS – Sodium meta bi sulphate

Sodium metabisulfite (SMBS), also known as sodium pyrosulfite, is a common chemical used in reverse osmosis (RO) systems, particularly for dechlorination. It acts as a reducing agent, effectively removing free chlorine from the water, which is crucial for preventing damage to RO membranes. SMBS is often preferred over other methods like carbon filters due to its ability to inhibit bacterial growth and foulin
