High Basicity Aluminum Chlorohydrate (ACH) with High Al2O3 Content - Top China Suppliers and Factory
Core Features
High degree of polymerization: The basicity is higher than that of ordinary polyaluminum chloride (PAC), second only to aluminum hydroxide.
Higher pH value: The aqueous solution is weakly acidic (pH 4-5), less acidic than ordinary polyaluminum. As hot areas usually have more acidic water, the treatment effect of ACH is better. Chlorinated aluminum hydroxide is more suitable for the markets in Southeast Asia and the Americas.
Broad-spectrum applicability: It can effectively coagulate within the pH range of 5-9.5, reducing the dependence of water treatment on pH value.
High-efficiency flocculation: Through electrochemical, adsorption, precipitation and other processes, it rapidly removes suspended solids, heavy metal ions (such as iron, cadmium, lead, mercury), organic matter and radioactive pollutants.
Low dosage: The unit treatment effect is 30% better than that of ordinary polyaluminum chloride, reducing the dosage of chemicals and the amount of sludge generated.

Application Area
(1) Water Treatment
• Drinking water purification: As a flocculant, it removes impurities such as turbidity, TOC (total organic carbon), iron, fluoride, cadmium, etc.• Industrial wastewater treatment: Used for decolorization of printing and dyeing wastewater, oil removal from papermaking wastewater, heavy metal removal from electroplating wastewater, etc.
• Sludge reduction: Reduces sludge production by over 50%, lowering treatment costs.
(2) Daily Chemicals and Personal Care
• Antiperspirants and deodorants: Reduce sweat secretion by blocking sweat glands, inhibit bacterial growth, and are widely used in products such as roll-ons and sprays.• Cosmetic raw materials: Used in oil-control skin care products to regulate skin oil secretion.
(3) Industrial Applications
• Precision casting: Used as a mold coagulant and flame retardant.• Paper industry: Improve paper strength, whiteness, and smoothness, and reduce fiber loss.
• Rubber and Tanning: As a crosslinking agent and dimensional stabilizer.
• Petroleum and Chemical Industry: Used for oil well profile control, drilling fluid additives, etc.
(4) Other Areas

Frequently Asked Questions
Q
What is Aluminum Chlorohydrate (ACH) and how does it differ from ordinary Polyaluminum Chloride (PAC)?
Aluminum Chlorohydrate (ACH) is a high-basicity aluminum salt coagulant with a basicity higher than ordinary PAC, second only to aluminum hydroxide. Its aqueous solution is weakly acidic (pH 4–5), making it less corrosive and more effective in treating acidic water sources common in tropical regions such as Southeast Asia and the Americas.
Q
What pH range is ACH effective for water treatment?
ACH can effectively coagulate within a broad pH range of 5 to 9.5. This wide applicability reduces the dependence of water treatment processes on strict pH control, making it highly versatile for various water sources and industrial applications.
Q
What contaminants can Aluminum Chlorohydrate remove from water?
ACH can rapidly remove a wide range of contaminants through electrochemical, adsorption, and precipitation processes. These include suspended solids, heavy metal ions (such as iron, cadmium, lead, and mercury), organic matter, turbidity, TOC (total organic carbon), fluoride, and even radioactive pollutants.
Q
How is ACH used in personal care and cosmetic products?
ACH is widely used in antiperspirants and deodorants, where it works by blocking sweat glands to reduce sweat secretion and inhibiting bacterial growth. It is commonly found in roll-on and spray formulations. It is also used as a cosmetic raw material in oil-control skin care products to help regulate skin oil secretion.
Q
What are the packaging options and shelf life of ACH liquid?
ACH liquid is available in multiple packaging options including 200L plastic drums, 1000L IBC totes, and container liquid bags for bulk shipments. When stored sealed in a cool, dry place away from direct sunlight, the liquid form has a shelf life of 1 year and does not hydrolyze over a long period of time.
Q
How does ACH compare to ordinary PAC in terms of dosage and sludge generation?
ACH offers significantly better performance per unit than ordinary polyaluminum chloride — its unit treatment effect is approximately 30% better than standard PAC. This means less chemical is required to achieve the same treatment result, which also leads to a substantial reduction in sludge production (over 50% less), lowering overall treatment costs and environmental impact.
