www.ultra-s3.com 1 On-Site Treatability Study for Destruction of Sulfide Melbourne, Florida A survey was conducted of total sulfides within Lift Station 23 in Melbourne, Florida’s north end sewerage collection system. Pretreatment results over two weeks of testing indicated that hydrogen sulfide within the air ranged from 500 ppm to over 1000 ppm. Total sulfides within the wastewater column averaged from 9 ppm to 12 ppm over two 24 hour sampling events. Flows into LS 23 range from 1.5 million gallons per day (MGD) to 2.1 MGD. The calculated dosage of Ultra-S3/hydrogen peroxide necessary to achieve successful reduction of sulfides to less than 1.5 ppm within the water column and less than 200 ppm within the air was approximately 56 gallons per day (GPD). Actual treatment of the lines c
