AWWA WQTC60594

A pilot study was conducted to compare the effectiveness of ozone and potassium permanganatefor iron and manganese precipitation for a natural groundwater in Queens, New York.The oxidants were tested under various contact times, dosages, and pH levels. In addition, ozonetesting included an evaluation of byproduct formation of aldehydes and bromate, andbiostability sampling.Ozone was found to be the more effective oxidant. It required a lower dosage, less contact time,and no pH adjustment of the groundwater (natural pH is 6) prior to oxidation. Byproductformation and biofouling of the downstream membranes and water piping were also not an issueduring the testing. Includes 11 references, tables, figures.
