Aluminium Chlorohydrate (ACH)
- Chemical Name: Aluminium Chlorohydrate
- Chemical Formula: Al₂(OH)₅Cl (generalized formula)
- CAS Number: 12042-91-0
- Appearance: Clear to pale yellow liquid or white powder (solid form)
- Solubility: Highly soluble in water
Aluminium Chlorohydrate (ACH) is a high-purity, polymerized aluminum salt widely used in water treatment chemicals, personal care products, and industrial applications.
It is considered one of the most effective and concentrated forms of aluminum-based coagulants.
Applications of Aluminium Chlorohydrate
Water Treatment Industry
ACH is extensively used by water treatment chemicals suppliers and commercial water treatment companies for:
- Drinking water purification
- Wastewater treatment
- Industrial effluent treatment
- Municipal water treatment plants
Why ACH is preferred?
- High charge density
- Lower sludge production
- Works efficiently in a wide pH range
- Better turbidity removal than traditional alum
ACH is more advanced compared to conventional coagulants like Aluminium Sulfate and can partially replace Poly Aluminium Chloride in high-performance systems.
Personal Care & Cosmetics
ACH is a key ingredient in:
- Antiperspirants
- Deodorants
- Cosmetic formulations
It helps control sweating by forming a temporary gel plug in sweat glands.
Paper & Textile Industry
- Paper sizing
- Dye fixing
- Process water clarification
Advantages of Aluminium Chlorohydrate
- High basicity (up to 83%)
- Lower dosage required
- Reduced sludge volume
- Improved clarity & filtration
- Cost-effective for large-scale water treatment
Typical Specifications (Industrial Grade)
| Parameter | Typical Range |
|---|---|
| Al₂O₃ Content | 23–24% |
| Basicity | 75–83% |
| pH (1% Solution) | 3.5–4.5 |
| Iron Content | ≤ 0.01% |
Why Choose ACH for Water Treatment?
Compared to standard coagulants, ACH offers:
- Faster floc formation
- Better performance in cold water
- Lower residual aluminum
- Stable performance in variable raw water conditions
For industries searching for reliable water treatment chemicals suppliers, ACH is considered a premium-grade solution due to its efficiency and consistency.
Packaging & Storage
- Available in HDPE drums, IBC tanks, and bulk tankers
- Store in a cool, dry place
- Avoid contact with strong alkalis
