The effectiveness of any chemical in water treatment is deeply rooted in its molecular structure and chemical behavior. Aluminum Chlorohydrate (ACH) stands out as a leading coagulant due to its advanced scientific properties, specifically its high degree of polymerization and consequently high cationic charge. NINGBO INNO PHARMCHEM CO.,LTD. offers precisely formulated ACH products, engineered to harness these scientific advantages for optimal treatment outcomes.

At its core, ACH is not a single compound but rather a family of inorganic aluminum salts with a general formula that reflects a complex polymeric structure, often represented as AlnCl(3n-m)(OH)m. The key to its superior performance lies in the high basicity, typically ranging from 75-90%. Basicity, in this context, refers to the proportion of hydroxyl groups (OH-) associated with the aluminum ions within the molecule. A higher basicity indicates a more highly polymerized structure and, crucially, a greater density of positive charge on the aluminum species.

This high cationic charge is the primary driver of ACH's efficacy as a coagulant. In water treatment, contaminants such as suspended solids and dissolved organic matter are often negatively charged (anionic). The highly positively charged ACH molecules efficiently neutralize these negative charges, destabilizing the colloidal suspensions. This neutralization is the first step in coagulation, allowing particles that were previously repelling each other to begin to aggregate.

Following charge neutralization, the polymeric nature of ACH facilitates bridging mechanisms. The long, chain-like aluminum-hydroxide polymers can physically span across multiple destabilized particles, binding them together. This process leads to the formation of larger, more robust flocs. These ACH-induced flocs are typically denser and more compact than those formed by simpler inorganic salts like aluminum sulfate. The increased density and size of these flocs are critical for efficient removal through sedimentation and filtration processes.

Furthermore, the structure of ACH contributes to its effectiveness over a wider pH range. Many traditional coagulants are highly sensitive to pH, requiring careful adjustment to remain effective. ACH, due to its inherent alkalinity and stable polymeric structure, can perform efficiently in pH ranges from approximately 5 to 9.5, making it a more forgiving and versatile option for varying raw water chemistries. This broad operational window reduces the complexity and chemical cost of water treatment.

The scientific understanding of ACH’s molecular behavior is what distinguishes it as a high-performance coagulant. NINGBO INNO PHARMCHEM CO.,LTD. leverages this scientific knowledge in its production processes to ensure that the ACH supplied consistently delivers the desired high charge density and optimal polymerization for superior water purification and industrial applications.

In essence, the effectiveness of ACH isn't magic; it's a direct result of sophisticated inorganic chemistry. Its ability to form highly charged, polymeric species makes it an unparalleled tool for tackling even the most challenging water quality issues.
