ACH stands for Aluminum Chlorohydrate, with CAS number 12042-91-0. ACH Chinese names are hydroxyaluminum chloride, basic aluminum chloride, or polyaluminum chloride, and its molecular formula is Al2 (OH) 5Cl · 2H2O. It is an inorganic polymer compound with a higher alkalinity (basicity) than polyaluminum chloride, second only to aluminum hydroxide. It undergoes bridging polymerization through hydroxyl groups, with the highest number of hydroxyl groups in the molecule.The aluminum oxide content in liquid ACH products is over 23%, while the aluminum oxide content in solid ACH products is between 46% and 50%. Has strong bridging and adsorption properties, is easily soluble in water, and undergoes physical and chemical processes such as electrochemistry, coagulation, adsorption, and precipitation during hydrolysis.

As a flocculant, it is mainly used for special water quality treatment of drinking water and water supply, such as printing and dyeing wastewater, to remove iron, fluorine, cadmium, and radioactive pollution. It is commonly used in environments with DH values greater than 7.5. Advantages: - Improved turbidity removal - Improved color removal - Enhanced removal of TOC (total organic carbon) - Reduced filtration turbidity - Increased filtration stroke - Reduced sediment by over 50% - Simplified operation, eliminated pH value and secondary polyelectrolyte addition - Reduced overall treatment cost.
The storage tanks and pipelines for polyaluminum solution should be made of materials that are corrosion-resistant. Fiberglass reinforced plastic, PVC, high-density polyethylene (HDPE), or rubber materials are the materials chosen for pipelines and storage tanks. Metering pumps and other equipment that come into contact with concentrated polyaluminum solutions must also use acid resistant materials such as PVC, rubber, polytetrafluoroethylene, ceramics, and Hastelloy C-type. Components that do not come into contact with liquids can be made of any material, such as carbon steel, stainless steel, copper, or aluminum.
Q1: What is the difference between aluminum chloride and polyaluminum chloride?
A1: Aluminum chloride (AlCl₃) is an inorganic compound commonly used in organic synthesis and as a catalyst. Polyaluminum chloride (PAC) is an inorganic polymer coagulant primarily used in water treatment. They differ significantly in structure, purpose, and application areas.
Q2: What is the difference between aluminum chloride and aluminum chloride hexahydrate?
A2: Aluminum chloride (AlCl₃) is the anhydrous form, typically appearing as a white solid. Aluminum chloride hexahydrate (AlCl₃·6H₂O) is its hydrated form, appearing as colorless crystals. They differ in physical properties and applications.
Q3: What are the differences in applications between aluminum chloride and ferric chloride?
A3: Aluminum chloride is primarily used as a catalyst in organic synthesis, while ferric chloride (FeCl₃) is commonly used as a coagulant in water treatment. They differ in chemical properties and application fields.
Q4: How do aluminum chloride and aluminum sulfate differ in water treatment roles?
A4: Both aluminum chloride and aluminum sulfate can be used as coagulants in water treatment. However, aluminum sulfate (Al₂(SO₄)₃) is more commonly used due to its lower cost and stable effectiveness. Aluminum chloride, being more acidic, requires careful pH control during use.
Q5: What is the difference between aluminum chloride and calcium chloride?
A5: Aluminum chloride (AlCl₃) and calcium chloride (CaCl₂) are distinct compounds. Aluminum chloride is mainly used in organic synthesis and as a catalyst, while calcium chloride is commonly used for de-icing, as a desiccant, and as a food additive. They differ in chemical properties and application areas.
