Magnesium Hydroxide Addition for Odor and Corrosion Control in Conveyance Systems: Product Selection and Dose Optimization

摘要

Gwinnett County Department of Water Resources uses magnesium hydroxide (Mg(OH)2) in the collection systems to aid with odor and corrosion control. This study was conducted to establish a common testing protocol to compare various commercial Mg(OH)2 products to help achieve the target pH of 8.5 within a 150-minute testing period. Parameters such as particle size distribution, magnesium hydroxide content, and dosage requirements were analyzed to compare product performance.
