The pursuit of clean water is a fundamental aspect of public health and industrial sustainability. At the heart of effective water treatment lies coagulation, a critical process that initiates the removal of impurities. Aluminum Chlorohydrate (ACH) has emerged as a high-performance coagulant, distinguished by its advanced chemical properties and superior efficacy. As a leading manufacturer and supplier, we are dedicated to providing high-quality ACH that professionals can rely on to achieve exceptional water quality.

The efficacy of ACH as a coagulant is rooted in its sophisticated inorganic polymer structure. Unlike simpler metal salts such as alum, ACH is a highly polymerized species of aluminum. This polymerization results in molecules with a significantly higher positive charge density. In water treatment, contaminants such as suspended solids, organic matter, and colloidal particles typically carry a negative surface charge. The highly cationic nature of ACH allows it to effectively neutralize these charges through a process known as charge neutralization. This destabilizes the particles, preventing them from repelling each other.

Following charge neutralization, ACH facilitates flocculation. The destabilized particles begin to aggregate, forming larger, amorphous masses called flocs. ACH's structure promotes the formation of strong, dense flocs that settle rapidly. This is a significant advantage over the lighter, fluffier flocs produced by some traditional coagulants, which can be more easily carried over into downstream filtration stages. The rapid sedimentation of ACH-formed flocs leads to a more efficient separation of impurities from the water, resulting in clearer settled water and improved filter performance.

The high basicity of ACH (often exceeding 80%) is another key scientific attribute. Basicity refers to the degree of neutralization of the aluminum salt by hydroxyl ions. A higher basicity indicates a more highly polymerized and positively charged aluminum species. This characteristic means ACH requires less alkalinity from the raw water to achieve effective coagulation, thus minimizing its impact on the water's pH. This property is particularly beneficial in waters with low natural alkalinity, where other coagulants might cause a significant drop in pH, requiring additional chemical intervention.

Furthermore, ACH's high concentration of aluminum oxide (Al2O3) means that a smaller dosage is required to achieve desired treatment results compared to less concentrated coagulants. This reduced dosage translates directly into lower chemical consumption, less generated sludge, and consequently, lower disposal costs. For water treatment professionals, understanding these scientific principles behind ACH—its polymerization, charge characteristics, high basicity, and concentrated form—is essential for optimizing treatment strategies and achieving superior outcomes. We are committed to supplying ACH that meets these high scientific standards, ensuring our customers receive a product that delivers consistent, high-performance results for all their water treatment needs.
