This document is a detailed specification attachment for a magnesium hydroxide procurement contract, specifically for the William E. Dunn Water Reclamation Facility in Florida. The contract involves orders for approximately 3,800 gallons of liquid bulk magnesium hydroxide per delivery, with strict requirements for bidders to be either manufacturers or manufacturers' authorized vendors. Bidders must submit a technical service plan addressing staff training, emergency technical assistance, and product efficiency evaluation. The bid will be evaluated based on the most advantageous projected cost to the City, with specific chemical and physical specifications outlined for the magnesium hydroxide slurry.

The specification document provides comprehensive technical requirements for the magnesium hydroxide, including detailed chemical composition parameters such as slurry basis, dry solids basis, physical properties, and performance specifications. Key technical requirements include production from seawater or magnesium chloride brine using a wet milling process, median particle size limitations, specific surface area requirements, and a stabilized residual test criteria. The vendor must ensure the magnesium hydroxide slurry is capable of cost-effectively providing noncarbonated alkalinity for biological treatment plant processes, with strict limitations on calcium oxide content (not exceeding 2.0% by weight) to prevent water softening and minimize precipitation of magnesium and calcium.
