THIOGUARD Magnesium Hydroxide

Nitrate Substitution for Wastewater

In a recent head-to-head trial, THIOGUARD proved to be a better substitute to Nitrate for wastewater treatment plants. With Nitrate feeding at 80 gallons per day and $1.90/gallon, THIOGUARD outperformed Nitrate by feeding < 40 gallons per day at $2.05/gallon, saving 40% in dollar savings and achieving 97% improvement in reduction of H₂S gas levels.
