Esseco produce a wide range of sulphur dioxide derivatives based on sodium, ammonia and potassium for use in the waste, industrial and potable water treatment industries.
Our sulphites are commonly used to remove dissolved oxygen from industrial water used in boilers systems. Sodium metabisulphite and bisulphite are used to remove chlorine from potable water (including reverse osmosis system) or to reduce hexavalent chrome in chrome plating effluent.
