Understanding the scientific principles behind chemical agents is crucial for optimizing their application and achieving desired results. Polyaluminium Chloride (PAC) is a powerful coagulant widely used in water treatment, and its efficacy stems from complex chemical interactions within the water. NINGBO INNO PHARMCHEM CO.,LTD, as a leading polyaluminium chloride manufacturer, is dedicated to explaining the science that makes PAC such an effective tool for cleaner water.

At its core, PAC is an inorganic polymer that acts as a precursor to aluminum hydroxide. When PAC is introduced into water, it undergoes hydrolysis, releasing positively charged aluminum species. These positively charged species are highly effective at neutralizing the negatively charged colloidal particles that cause turbidity and color in water. This process, known as charge neutralization, destabilizes the colloidal suspension, causing the particles to approach and adhere to one another.

Following charge neutralization, a process called sweep flocculation occurs. As the aluminum species hydrolyze further, they form large, amorphous precipitates of aluminum hydroxide. These precipitates act like microscopic nets, trapping and enmeshing the destabilized colloidal particles, as well as other suspended solids and dissolved organic matter. This aggregation forms larger, heavier particles, known as flocs, which can be easily removed from the water through sedimentation or filtration. The efficiency of PAC as a water treatment chemical pac is largely attributed to this dual mechanism.

The specific properties of PAC, such as its basicity and the distribution of its polymeric species, influence its performance. Higher basicity generally indicates a greater proportion of polynuclear aluminum species, which are more effective coagulants at lower dosages and across a wider pH range. This is why NINGBO INNO PHARMCHEM CO.,LTD offers various grades, including polyaluminium chloride with high basicity, to cater to diverse water treatment needs, from industrial wastewater treatment to drinking water purification. Our commitment as a drinking water purification chemical provider ensures that the science translates into safe water.

The reaction kinetics and the formation of aluminum hydroxide precipitates are influenced by factors such as pH, temperature, and the presence of other ions in the water. Understanding these variables allows water treatment professionals to optimize the use of PAC for maximum efficiency. By choosing to buy PAC from NINGBO INNO PHARMCHEM CO.,LTD, clients gain access to products backed by a deep understanding of the underlying chemical processes, ensuring superior water quality and environmental compliance.
