Sodium Aluminate Solutions
Sodium Aluminate is most widely used in municipal drinking water and waste water treatment systems. As an alkali, Sodium Aluminate can work in applications where the addition of caustic is not desirable. It provides an economical source of highly reactive alumina.
Liquid sodium aluminate (LSA) is becoming an increasingly popular choice for the removal of phosphorus in municipal and industrial wastewater plants. As discharge limits for nitrogen and phosphorus become more stringent, many plants are implementing both biological and chemical treatment systems for their reduction. However, both these treatment processes can deplete the available alkalinity and depress effluent pH below discharge limits.
Sodium Aluminate Solutions Specs
The USALCO® manufacturing process utilizes only the finest available raw materials in the production of USALCO Sodium Aluminate Solutions, in which alumina tri-hydrate (ATH) is dissolved into sodium hydroxide and water. Proprietary stabilization techniques may also be used to prevent alumina from precipitating. USALCO Sodium Aluminate Solutions are strongly alkaline products that are available in three strengths:
- 38% solution
- 43% solution
- 45% solution
All strengths of liquid Sodium Aluminate meet the specifications of the American Water Works Association Standard (AWWA) B405-16 and comply with the requirements of NSF/ANSI/CAN 60 at maximum dosages of 89 to 105 mg/L. If a dry product better suits your application, USALCO also offers granular Sodium Aluminate GU – 55 (dry sodium aluminate).
Transportation & Packaging
USALCO® provides Sodium Aluminate in bulk truckload quantities for municipalities and industrial users. We use dedicated trucks to insure quality and have multiple plants to meet your needs.
