Ensuring access to clean water is a fundamental necessity, and the efficacy of the chemicals used in this process is paramount. NINGBO INNO PHARMCHEM CO.,LTD. highlights the crucial role of Polyaluminium Chloride (PAC) as a powerful flocculant, explaining the scientific principles behind its exceptional performance in water treatment.

Water sources often contain a variety of impurities, including dissolved organic matter, suspended solids, colloids, and fine particles. Many of these impurities carry a negative electrical charge, which causes them to repel each other and remain dispersed in the water. The process of coagulation and flocculation is designed to overcome this repulsion, aggregate these particles, and allow them to be removed through sedimentation and filtration.

Polyaluminium Chloride is a highly efficient coagulant because of its unique chemical structure. It is essentially a pre-polymerized inorganic salt containing multiple aluminum ions bridged by hydroxyl groups. This structure gives PAC a high positive charge density. When introduced into water, the positively charged PAC molecules rapidly neutralize the negative charges on the suspended impurities. This process, known as charge neutralization, destabilizes the particles, making them more prone to aggregation.

Following charge neutralization, the bridging action of the PAC polymer chains becomes critical. These long polymer chains can physically connect the destabilized particles, forming larger, more amorphous aggregates called flocs. The quality of these flocs is crucial for efficient removal. PAC is known for forming large, dense, and compact flocs that settle rapidly. This rapid settling significantly reduces the time required for clarification in sedimentation tanks, thereby improving the overall efficiency of the water treatment process.

The effectiveness of polyaluminium chloride as a flocculant is further enhanced by its broad applicability. Unlike simpler inorganic salts, PAC's polymeric nature allows it to function effectively over a wider range of pH and water temperatures. This makes it a versatile choice for various water sources and treatment conditions. For those looking to buy polyaluminium chloride, understanding its flocculating mechanism highlights why it's a preferred choice over traditional coagulants for achieving superior water clarity.

When considering the correct polyaluminium chloride dosage, it's essential to perform jar tests to optimize the amount of chemical needed for specific water conditions. This ensures that the maximum flocculation efficiency is achieved without overdosing. At NINGBO INNO PHARMCHEM CO.,LTD., we are committed to providing high-quality PAC that delivers exceptional flocculation performance, contributing to the production of safe and clean water for both municipal and industrial use.
