Product name: Nalco 3688
Manufacturer: Ecolab / Nalco Water (industrial water-treatment chemicals)
Nalco 3688, documented as Blue Coral Hi pH 3688, is a highly alkaline liquid cleaner (pH 13.0–14.0) utilized for heavy-duty industrial applications, including process water management in the pulp and paper industry. It acts as a degreaser and is used to prevent scale in boiler systems.

To appreciate NALCO 3688, one must first grasp the difficulty of the Bayer process. Bauxite ore, the primary source of aluminum, contains only 30-60% aluminum hydroxide. The remainder is a complex mixture of impurities, most notably iron oxides, silica, and titanium dioxide. The Bayer process dissolves the aluminum content using caustic soda (sodium hydroxide) under high heat and pressure, creating a sodium aluminate solution. However, this leaves behind a voluminous, highly alkaline slurry of red mud—a problematic waste containing the undissolved impurities. The central challenge of the refinery is to rapidly and efficiently separate the valuable, clear sodium aluminate liquor from this red mud. Gravity settling alone is far too slow, potentially taking weeks, which would make aluminum production economically unviable. Nalco 3688 — Technical Summary Product name: Nalco
