Selecting the optimal flocculant is a critical decision for any water treatment facility aiming for efficient impurity removal and high water quality. While various chemical options exist, Aluminum Sulfate (Al2(SO4)3) stands out as a workhorse coagulant due to its effectiveness, affordability, and widespread availability. As a leading manufacturer and supplier of water treatment chemicals, NINGBO INNO PHARMCHEM CO.,LTD. offers high-quality 17% iron-free Aluminum Sulfate, and we understand the nuances of choosing the right solution for diverse water treatment challenges.

Aluminum Sulfate's primary mechanism involves charge neutralization and sweep flocculation. When added to water, it hydrolyzes to form aluminum hydroxide, a positively charged precipitate that adsorms negatively charged suspended particles, colloidal matter, and dissolved organic compounds. These destabilized particles then aggregate into larger, heavier flocs that are easily removed by sedimentation and filtration. Its effectiveness is particularly pronounced in treating raw water with moderate turbidity and alkalinity. The 17% iron-free grade (CAS No. 10043-01-3) is preferred when low iron content in the treated water is a strict requirement, such as in drinking water purification.

Compared to other common flocculants like Ferric Sulfate or Polyaluminum Chloride (PAC), Aluminum Sulfate often presents a more economical option, especially for large-scale operations. Ferric Sulfate is also a strong coagulant but can sometimes contribute to higher levels of iron in treated water and may cause more aggressive corrosion. PAC, on the other hand, is a pre-hydrolyzed aluminum compound that can be effective over a wider pH range and often requires lower dosage, but it can be more expensive. The choice often depends on specific water characteristics, treatment goals, and budget constraints.

For applications in the paper industry, Aluminum Sulfate also plays a crucial role in sizing and improving paper strength. Similarly, in the textile sector, it acts as a mordant for dyeing. Its versatility makes it a valuable chemical for various industrial processes.
