NSF Standard 60 ACH Aluminum Chlorohydrate Coagulant for Surface Water Treatment and Turbidity Removal

Product Overview

Bluwat Chemicals supplies NSF Standard 60 ACH Coagulant for surface water treatment, turbidity removal, and municipal drinking water clarification. ACH, also known as Aluminum Chlorohydrate, Aluminum Hydroxychloride, or Aluminum Chlorhydrol, is a high-basicity aluminum-based coagulant used to remove suspended solids, colloidal particles, turbidity, color, and organic matter from raw water.

Surface water sources such as rivers, lakes, and reservoirs often contain variable levels of silt, clay, algae, natural organic matter, color, and fine suspended particles. These impurities can change significantly after rainfall, seasonal temperature changes, flooding, or biological activity. A stable and efficient coagulant is essential for maintaining reliable drinking water quality.

NSF Standard 60 ACH Coagulant offers strong coagulation performance, broad pH adaptability, and low impact on treated water pH, making it suitable for surface water treatment plants that require consistent clarification results.

What Is ACH Coagulant?

ACH Coagulant is a concentrated inorganic polymer coagulant with high Al2O3 content and high basicity. Its molecular formula is Al2(OH)5Cl·2H2O. It contains highly active polymeric aluminum species that can effectively destabilize suspended particles and colloids in raw water.

When ACH is added to surface water, it neutralizes the negative charges on fine particles. These destabilized particles then combine into larger flocs during the flocculation stage. The flocs can be removed by sedimentation, clarification, flotation, or filtration.

Because ACH has a high degree of neutralization, it usually causes less pH reduction than many conventional metal salt coagulants. This is especially useful for surface water treatment plants that need stable operation under changing raw water conditions.

Why Surface Water Needs Effective Coagulation

Surface water is one of the most common sources for municipal drinking water. However, it often contains impurities that cannot be removed by simple filtration alone.

Without effective coagulation, these fine particles may pass through sedimentation and filtration systems, causing poor water clarity, higher filter load, and unstable treated water quality. NSF Standard 60 ACH Coagulant helps drinking water plants improve particle removal and maintain stable clarification performance.

Key Benefits

1. NSF Standard 60 Certified for Drinking Water Applications

NSF Standard 60 ACH Coagulant is suitable for potable water treatment applications where certified water treatment chemicals are required. It supports municipal water treatment plants, water utilities, contractors, and distributors serving drinking water projects.

2. Excellent Turbidity Removal

ACH effectively removes turbidity caused by suspended solids, fine particles, silt, clay, and colloids. It helps produce clearer water and improves the performance of downstream filtration systems.

3. Strong Performance for River, Lake, and Reservoir Water

Surface water quality can change quickly. ACH provides stable coagulation performance for different raw water sources, including river water, lake water, reservoir water, and mixed surface water sources.

4. High Basicity and Low pH Impact

With high basicity, ACH has a lower influence on treated water pH. This helps reduce the need for additional pH correction chemicals and supports more stable plant operation.

5. Lower Dosage Potential

Due to its high Al2O3 content and strong charge neutralization ability, ACH can often achieve effective coagulation at lower dosage levels compared with many traditional coagulants.

6. Broad pH Working Range

ACH can perform across a broad pH range, which is helpful when raw water pH changes due to seasonal or environmental conditions.

Main Applications

NSF Standard 60 ACH Coagulant is suitable for:

Application in Surface Water Treatment Plants

In surface water treatment plants, ACH is usually added during the coagulation stage before flocculation and clarification. It can be dosed as a liquid product or prepared from powder into a solution before use.
