Abstract
Simultaneous application of ozone and ultraviolet light (UV185 and UV254) in water to be purified will create hydroxyl radicals, which combination will cause conversion of AS (III) that may be present to As (V), oxidation of inorganic matter such as manganese, sulfur, phosphorus and organic matter and provide virucidal and germicidal effects to purify the water.
