Aluminium chloro hydrate powder
Aluminum chlorohydrate is a compound used as an antiperspirant. Aluminum chlorohydrate is a group of water-soluble aluminum complexes with the general formula AlnCl(3n-m)(OH)m. It is included up to 25% in over-the-counter hygiene products as an activ
Application & Uses
Applications
Aluminium Chlorohydrate is commonly used for:
- Drinking-water treatment
- Municipal wastewater treatment
- Industrial effluent treatment
- Raw-water clarification
- Turbidity and suspended-solids removal
- Colour reduction
- Clarification prior to filtration
- Paper and pulp processing
- Textile wastewater treatment
- Industrial process-water treatment
- Sludge conditioning
- Oil and grease removal in suitable wastewater systems
Dosage & Directions for Use
Application & Dosage
ACH can normally be dosed neat or diluted with clean water before injection. It should be introduced at a location providing rapid initial mixing, followed by sufficient flocculation time.
The optimum dosage depends on turbidity, suspended solids, organic loading, pH, alkalinity and treatment objectives. Laboratory jar testing is recommended to establish the most economical dosage for each water source.
For wastewater applications, ACH can also be used in combination with a suitable polyacrylamide flocculant such as RXSOL PAM Emulsion 1630 where larger floc formation and improved settling or dewatering are required.

Product Description & Chemical Profile
Aluminium Chlorohydrate (ACH)
Product Description
Aluminium Chlorohydrate (ACH) is a highly concentrated inorganic aluminium-based coagulant used primarily for water and wastewater treatment. It is a pre-polymerized aluminium salt with high aluminium content and high basicity, providing efficient coagulation and flocculation over a relatively broad operating pH range.
ACH works by neutralizing the electrical charge of suspended and colloidal particles, allowing them to combine into larger flocs that can be removed through sedimentation, flotation or filtration.
Compared with conventional aluminium salts such as aluminium sulphate, ACH can provide lower dosage requirements, reduced sludge generation and less impact on treated-water pH and alkalinity, depending on the water characteristics and treatment process.
