Flocculation is a fundamental process in water treatment and many other industrial applications, aimed at aggregating dispersed particles into larger, settleable flocs. At the forefront of effective flocculants stands aluminium sulphate, a compound whose chemical properties make it exceptionally adept at this task. NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality aluminium sulphate, enabling industries to harness the power of flocculation for cleaner processes and better outcomes.

The mechanism of flocculation by aluminium sulphate is rooted in its behavior in aqueous solutions. When dissolved in water, aluminium sulphate undergoes hydrolysis, releasing positively charged aluminum ions (Al³⁺) and forming various polynuclear aluminum hydroxy complexes. These positively charged species play a crucial role in neutralizing the negative surface charges of suspended colloidal particles present in the water. Typically, impurities in water carry a negative charge, which causes them to repel each other, keeping them dispersed and stable. The addition of aluminium sulphate effectively neutralizes these charges, reducing electrostatic repulsion and allowing particles to approach each other more closely. This is the principle of charge neutralization, a primary mode of action for aluminium sulphate as a coagulant.

Following charge neutralization, a process known as sweep flocculation or enmeshment occurs. As more aluminium sulphate is added, positively charged aluminum hydroxide precipitates begin to form. These precipitates have a large surface area and a gelatinous texture, which effectively entrap or enmesh the destabilized colloidal particles and other suspended matter. This creates larger, heavier agglomerates known as flocs. The efficiency of this process, particularly for aluminium sulphate flocculation applications, is highly valued in sectors ranging from municipal water treatment to industrial wastewater management.

The benefits of using aluminium sulphate as a flocculant are significant. It is a highly cost-effective chemical for achieving water clarification and impurity removal. Its ability to produce dense, settleable flocs facilitates their easy separation from the treated water through sedimentation, filtration, or flotation. This makes it a critical component for industries that need to comply with stringent discharge limits or require high-purity process water.
