Aluminum Chlorohydrate: The Most Efficient Coagulant for Water Treatment

Aluminum chlorohydrate (ACH) is a water treatment chemical that is used to remove suspended particles and dissolved organic matter from water. It is a highly efficient coagulant, meaning that it requires less dosage than other coagulants to achieve the same results. This can save water treatment plants money on chemicals and operating costs.

The Highest Aluminum Concentration and Basicity:
Solid aluminum chlorohydrate powder owns aluminum concentration around 46% [Al2O3(w/w)]. Liquid ACH, i.e. Aluminum chlorohydrate 50% solution owns aluminum concentration 23% [Al2O3(w/w)]. It is the highest aluminum concentration in all commercially available aluminum-based solution. The basicity of Aluminum Chlorohydrate at 83% is also the highest in all commercially available polyaluminum chloride-based solution. Basicity refers to the degree of acid neutralization and represents a measure of how highly polymerized the aluminum is in Aluminum Chlorohydrate (ACH).

Wide pH Range:
Because of its 83% high basicity, ACH can be used over a wide pH range of 5-9.5, making it a versatile coagulant that can be used in a variety of water treatment applications. It is commonly used in drinking water treatment, wastewater treatment, and industrial water treatment.

Less Dosage:
Aluminum chlorohydrate owns the highest aluminum concentration and basicity in all commercially available aluminum-based solution. To treat the same raw waters, Aluminum chlorohydrate requires the minimum dosage.

Low Sludge Production:
ACH produces less sludge than other coagulants, such as alum and ferric chloride. This is because ACH forms a more compact floc than these other coagulants. The compact floc is easier to settle and filter, which means that less sludge is produced.

No Heavy Metals:
ACH does not contain any heavy metals. This makes it a safe and environmentally friendly coagulant. Heavy metals can be harmful to human health and the environment, so it is important to use a coagulant that does not contain them.

Less Aluminum Residue:
By well controlling the dosage of ACH Aluminum chlorohydrate, aluminum residue even can’t be detected in treated outlet water, with less aluminum residue. ACH Aluminum chlorohydrate is in NSF(National Sanitation Foundation) Official Listings as Drinking Water Treatment Chemicals - Coagulation & Flocculation. ACH Aluminum chlorohydrate is safe for drinking water treatment.

Safe for Storage:
Aluminum chlorohydrate is not corrosive. Stable for long-term storage.

How ACH Works to Treat Water:
ACH works by reacting with the impurities in water to form larger particles. These larger particles are then easily removed from the water through sedimentation or filtration.

The reaction of ACH with impurities in water is called coagulation. Coagulation is a physical process that occurs when two or more particles come into contact with each other and form a larger particle. The larger particle is called a floc.

The floc is formed when the positively charged aluminum ions in ACH react with the negatively charged impurities in water. The positive and negative charges attract each other, and the particles form a larger particle.

The floc is then easily removed from the water through sedimentation or filtration. Sedimentation is the process of allowing the floc to settle to the bottom of the water. Filtration is the process of passing the water through a filter, which removes the floc.

Conclusion:
ACH is a highly efficient, versatile, and safe coagulant that can be used in a variety of water treatment applications, especially for drinking water treatment. It is a valuable tool for water treatment plants that are looking to improve the quality of their water.

If you are looking for a coagulant that is efficient, versatile, and safe, then ACH is a good option for you.
