High Basicity Aluminum Chlorohydrate (ACH) with High Al2O3 Content - China Suppliers & 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 effective in acidic water conditions typical of tropical regions. ACH also requires a 30% lower dosage than standard PAC for equivalent treatment results.
Q
What pH range is ACH effective 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 highly versatile across different water sources and conditions.
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), total organic carbon (TOC), fluoride, turbidity, and even radioactive pollutants. It is suitable for both drinking water purification and industrial wastewater treatment.
Q
Is ACH suitable for use in personal care and cosmetic products?
Yes. ACH is widely used in the personal care industry as an active ingredient in antiperspirants and deodorants. It works by temporarily blocking sweat glands to reduce perspiration and inhibiting bacterial growth that causes odor. It is also used in oil-control skincare formulations to help regulate skin oil secretion.
Q
What packaging options are available for ACH and how should it be stored?
ACH in liquid form is available in 200L plastic drums, 1000L IBC totes, or container liquid bags for bulk shipment. It should be stored in a cool, dry place away from direct sunlight. When kept sealed, the liquid product has a shelf life of 1 year and remains stable without hydrolysis over extended storage periods.
Q
What are the key technical specifications of ACH?
The key technical parameters of ACH include: Relative Density (25℃) of 1.33–1.38; Al₂O₃ content of 23–24%; basicity greater than 80%; pH value of 4.0–4.4 (30% aqueous solution); Fe content ≤100 ppm; and SO₄²⁻ content ≤100 ppm. These specifications ensure consistent high performance in both industrial and consumer applications.
