Aluminium Chlorohydrate (ACH) is a versatile chemical widely used in various industries, particularly for water and wastewater treatment. Here is a summary of its primary applications:

1. Water Treatment:
   ACH is an effective coagulant used to remove suspended solids, turbidity, and organic matter from water. It helps in reducing color and improving clarity in both drinking water and wastewater treatment processes.

2. Wastewater Treatment:
   ACH is used in industrial wastewater treatment to remove pollutants such as heavy metals, phosphates, and organic contaminants. It plays a key role in sludge dewatering, improving floc formation and separation.

3. Cosmetics and Antiperspirants:
   ACH is commonly used as an active ingredient in antiperspirants due to its ability to block sweat glands temporarily, reducing sweat production. It’s valued for being mild on the skin compared to other aluminum-based compounds.

4. Papermaking:
   In the paper industry, ACH is used as a retention aid, helping to improve paper quality by enhancing fiber bonding and reducing chemical consumption.

5. Textile Industry:
   ACH is used in the textile industry for dye-fixing processes, helping to improve the durability and vibrancy of dyes on fabrics.

6. Oil & Gas Industry:
   ACH is used in oil and gas applications to remove suspended solids, oil, and grease from water, especially in enhanced oil recovery processes and oilfield water treatment.
