The selection of an appropriate coagulant is a cornerstone of effective water treatment. For decades, Aluminum Sulfate (alum) has been a workhorse in the industry. However, advancements in chemical technology have led to the development of superior alternatives, with Poly Aluminium Chloride (PAC) standing out as a leading contender. As a dedicated manufacturer and supplier, we aim to provide insights into why PAC is increasingly becoming the preferred choice for diverse water treatment needs.

Aluminum Sulfate works by releasing aluminum ions that neutralize the negative charges on suspended particles, leading to flocculation. While effective, its performance is often limited by a narrower optimal pH range (typically 5.8-8.5) and a greater tendency to impact water pH, often requiring additional alkaline agents for correction. Furthermore, alum can result in higher residual aluminum levels in treated water and generate substantial volumes of sludge, increasing disposal costs.

Poly Aluminium Chloride, on the other hand, is a pre-hydrolyzed inorganic polymer coagulant. Its sophisticated structure provides a higher cationic charge density, enabling it to neutralize impurities more effectively. This results in faster floc formation and sedimentation, even in challenging water conditions. One of PAC's most significant advantages is its broad effective pH range, often spanning from 5.0 to 9.0, with optimal results typically achieved between pH 6.5 and 7.6. This wide applicability minimizes the need for pH adjustment chemicals, leading to simplified operations and reduced costs.

Key benefits of using PAC as your primary coagulant include:

1. Enhanced Efficiency: PAC’s superior charge density leads to more robust floc formation and faster settling times, improving the overall efficiency of sedimentation and filtration processes.

2. Lower Dosage Requirements: Typically, PAC can be used at significantly lower doses than alum to achieve equivalent or better results. This not only reduces chemical consumption but also leads to substantial cost savings.

3. Reduced Sludge Volume: PAC generates considerably less sludge compared to alum, simplifying waste management and lowering disposal expenses. This is a critical factor for environmental sustainability and operational efficiency.

4. Wider Application Range: PAC performs exceptionally well across varying water temperatures and pH levels, making it a versatile solution for diverse water sources, including industrial wastewater, municipal water, and even sensitive drinking water applications.
