High Basicity & High Al2O3 Content Aluminum Chlorohydrate (ACH) from 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.

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 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 suitable for treating acidic water sources commonly found in tropical and subtropical regions such as Southeast Asia and the Americas.
Q
What pH range is ACH effective in for water treatment?
ACH can effectively coagulate and flocculate within a broad pH range of 5 to 9.5. This broad-spectrum applicability significantly reduces the dependence of water treatment processes on strict pH control, making it versatile for various water sources.
Q
How much does ACH reduce sludge production compared to conventional coagulants?
ACH demonstrates a unit treatment effect approximately 30% better than ordinary polyaluminum chloride. This superior efficiency means less chemical dosage is required, and sludge production is reduced by over 50%, significantly lowering overall water treatment and disposal costs.
Q
What are the main application areas of Aluminum Chlorohydrate besides water treatment?
Beyond water treatment, ACH is widely used in daily chemicals and personal care products (antiperspirants, deodorants, oil-control cosmetics), industrial applications (precision casting, paper manufacturing, rubber and tanning, petroleum and chemical industries), as well as in medicine for treating hyperhidrosis and in graphite products to enhance fire resistance.
Q
What are the available packaging options for liquid ACH and how should it be stored?
Liquid ACH is available in 200L plastic drums, 1000L IBC totes, and liquid bags for flexible shipping options. It should be stored in a cool, dry place away from direct sunlight. When kept sealed, liquid ACH has a shelf life of 1 year and does not undergo hydrolysis over extended storage periods.
Q
What contaminants can ACH remove during water treatment?
ACH is highly effective at removing 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 including total organic carbon (TOC), fluoride, turbidity, and even radioactive pollutants, making it suitable for both drinking water purification and industrial wastewater treatment.
