High Basicity Aluminum Chlorohydrate (ACH) with High Al2O3 Content 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.

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
- Medicine: Ingredients of topical medications for treating hyperhidrosis.
- Graphite products: Enhance fire resistance and physical and chemical properties.

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 in Southeast Asia and the Americas.
Q
What pH range is ACH effective for water treatment?
ACH can effectively coagulate and flocculate within a broad pH range of 5–9.5, significantly reducing the dependence of water treatment processes on precise pH control and making it highly versatile for various water sources.
Q
What contaminants can ACH remove from water?
ACH can rapidly remove a wide range of contaminants through electrochemical, adsorption, and precipitation processes, including suspended solids, heavy metal ions (iron, cadmium, lead, mercury), organic matter, fluoride, total organic carbon (TOC), and radioactive pollutants.
Q
Is ACH used in personal care products?
Yes. ACH is widely used in antiperspirants and deodorants (roll-ons, sprays) as it reduces sweat secretion by blocking sweat glands and inhibits bacterial growth. It is also used as a cosmetic raw material in oil-control skin care products to regulate skin oil secretion.
Q
What packaging options are available for ACH liquid, and how should it be stored?
ACH liquid is available in 200L plastic drums, 1000L IBC totes, and liquid bags for container shipment. It should be stored in a cool, dry place away from direct sunlight. When properly sealed, it has a shelf life of 1 year and does not undergo hydrolysis over extended storage periods.
Q
How does ACH compare to ordinary PAC in terms of dosage and sludge generation?
ACH delivers a unit treatment effect that is approximately 30% better than ordinary polyaluminum chloride. This means less chemical dosage is required to achieve the same treatment result, and sludge production is reduced by over 50%, significantly lowering overall water treatment costs.
