Maintaining clean and safe water is a critical challenge for both industrial and municipal applications. One of the most widely used and reliable chemicals for achieving this goal is aluminum sulfate for water treatment. Known for its excellent coagulation performance and cost efficiency, aluminum sulfate, often referred to as alum, remains a cornerstone of modern water purification processes.
In Indonesia, Lautan Air Indonesia (LAI) stands out as a trusted manufacturer and supplier of high-quality aluminum sulfate, ensuring consistent product performance and reliable availability across the nation.
How Aluminum Sulfate Works in Water Treatment
The effectiveness of aluminum sulfate for water treatment lies in its function as a coagulant, which helps remove suspended solids, organic matter, and fine particles that make water cloudy or colored.
When aluminum sulfate is added to raw water, it reacts with the water’s natural alkalinity to form aluminum hydroxide, a gelatinous substance known as floc. This floc binds together small impurities (such as dirt, silt, bacteria, and organic materials) into larger, heavier particles that can easily settle during the sedimentation process.
The overall process can be summarized in three key stages:
- Coagulation: Aluminum sulfate neutralizes the electrical charges of suspended particles, allowing them to clump together.
- Flocculation: The tiny neutralized particles aggregate into larger flocs.
- Sedimentation and Filtration: These flocs settle to the bottom of the tank, and the clarified water above is filtered for further purification.
This process dramatically reduces turbidity and color, making aluminum sulfate a fundamental component in drinking water treatment plants, wastewater systems, and industrial water treatment facilities.
Because it works effectively across a wide range of pH and raw water conditions, aluminum sulfate remains one of the most versatile and dependable solutions for water treatment operations in Indonesia and worldwide.

The Benefits of Using Aluminum Sulfate
The popularity of aluminum sulfate in water treatment is not without reason. Its combination of performance, reliability, and cost-effectiveness offers a range of advantages that make it a preferred choice among operators and engineers alike.
1. Effective Coagulation and Clarification
Aluminum sulfate efficiently removes fine suspended solids that are too small to settle naturally. By promoting the formation of dense, easily separable flocs, it produces visibly clearer and cleaner water. This is essential for both industrial processes and potable use.
2. Enhances Filtration Efficiency
By reducing turbidity before the filtration stage, aluminum sulfate helps extend the lifespan and performance of filtration media. This translates to lower maintenance frequency and operational costs for treatment facilities.
3. Stable and Reliable Quality
Aluminum sulfate has a long history of use in water treatment and is recognized for its consistent results. It performs well under different water conditions and temperature ranges, ensuring predictable performance year-round.
With these benefits, aluminum sulfate continues to be the industry standard for achieving efficient and reliable coagulation in both municipal and industrial settings.
