Product Overview

Alliance Chemical provides high-quality Aluminum Sulfate 50% solution, which is a versatile liquid formulation widely utilized across various industrial sectors. This chemical agent — identified by CAS number 10043-01-3 — is formulated with an active concentration of 50%. It offers exceptional performance in bulk processes where precise chemical additions are required. Our liquid formulation simplifies handling by eliminating the dusting hazards and dissolution delays associated with dry solid alternatives. This addition to our premium salts catalog is highly efficient for continuous-flow operations.

Our Aluminum Sulfate 50% liquid is manufactured under strict quality standards to ensure stability and uniform composition. With a molecular formula of Al2O12S3 and a molecular weight of 342.2, this product acts as a highly effective coagulant and processing aid. Industrial operators rely on this liquid format for consistent dosing in continuous systems without the risk of clumping or incomplete dissolution. As a trusted Texas chemical supplier, Alliance Chemical ensures that each batch meets rigorous standards, providing reliability for demanding chemical processing facilities.

Why This Grade

Choosing the appropriate concentration of aluminum sulfate is critical for the efficiency and safety of industrial operations. While anhydrous or dry hydrate forms exist, a stable 50% liquid solution offers immediate reactivity without the energy costs and labor involved in mixing solid compounds. The 50% concentration is carefully balanced to maintain a low freezing point while maximizing active aluminum content, ensuring it remains fluid and pumping-ready even in moderate temperatures. Relying on an unverified or inconsistent concentration can cause severe process disruptions, including line clogging and dosing imbalances.

Furthermore, utilizing an incorrect concentration or lower grade of aluminum sulfate can lead to significant failure modes in processing equipment. Deviations in pH and active aluminum content can trigger premature precipitation, resulting in scale buildup, pump failure, and pipeline blockages. These issues require unscheduled maintenance downtime and can damage downstream equipment. By choosing our stabilized 50% solution, operators avoid these complications and maintain optimal process parameters. Our solution is designed specifically to prevent these mechanical and chemical failures in heavy industrial environments.

Industrial Applications

  • Water purification systems where it acts as an effective coagulant to bind suspended particles, facilitating sediment removal during clarification processes.
  • Sewage and municipal wastewater treatment to precipitate dissolved phosphorus and assist in sludge dewatering and clarification workflows.
  • Paper manufacturing processes where it serves as a sizing agent to improve paper strength, ink absorption, and water resistance.
  • Industrial firefighting foams where it functions as a stabilizer to generate durable, heat-resistant barrier bubbles for fire suppression.
  • Chemical manufacturing where it is used as a precursor or reactant to synthesize other aluminum compounds and specialty catalysts.

Hazmat & Shipping

This product is classified as a regulated hazardous material for transport. It is officially designated as **UN3264**, **Hazard Class 8**, **Packing Group II**, with the proper shipping name **Corrosive liquid, acidic, inorganic, n.o.s. (Aluminum sulfate solution)**. The GHS signal word for this chemical is **Danger**. GHS pictograms are not applicable as none are listed under this specific classification. It is critical that all transport and handling personnel are fully trained in hazmat compliance to ensure safe transit, unloading, and storage.

Because this product is a corrosive liquid that carries the hazard statements H290 (corrosive to metals) and H318 (causes serious eye damage), appropriate personal protective equipment (PPE) is mandatory during all handling phases. Operators must wear chemical-resistant gloves, protective clothing, and full face shields or splash goggles as specified under precautionary statement P280. Additionally, emergency eye wash stations must be readily accessible in the immediate work area. Please refer to the Safety Data Sheet (SDS) provided with every order for comprehensive compliance and safety information.

Handling & Storage

Proper storage and handling are essential to maintain the integrity of Aluminum Sulfate 50% and ensure workplace safety. This corrosive liquid must be stored in compatible, corrosion-resistant containers such as high-density polyethylene (HDPE), fiber-reinforced plastic (FRP), or rubber-lined steel. It is incompatible with strong bases, carbon steel, galvanized iron, and aluminum. Maintain storage temperatures within a stable range, avoiding extreme cold to prevent crystallization, as well as excessive heat. Ensure the storage area is well-ventilated and equipped with secondary containment systems to prevent environmental release in the event of a spill.
