NSF 60 Certified Aluminum Chlorohydrate ACH for Municipal Drinking Water Treatment
Product Overview
Bluwat Chemicals supplies NSF 60 Certified Aluminum Chlorohydrate ACH for municipal drinking water treatment and potable water clarification. Aluminum Chlorohydrate, also known as Aluminum Hydroxychloride or Aluminum Chlorhydrol, is one of the most concentrated products in the polyaluminum coagulant family.
Compared with traditional metal salt coagulants and standard PAC products, ACH provides higher alumina content, higher basicity, and stronger charge neutralization performance. These characteristics make it highly suitable for drinking water plants that require reliable clarification, stable water quality, and efficient chemical consumption control.
In municipal water treatment, raw water quality can vary depending on season, rainfall, river conditions, algae growth, suspended solids, and organic matter concentration. NSF 60 Certified ACH helps operators achieve stable coagulation performance across a broad pH range while minimizing the impact on treated water pH.
What Is Aluminum Chlorohydrate ACH?
Aluminum Chlorohydrate is an inorganic polymer coagulant with the molecular formula Al2(OH)5Cl·2H2O. It is widely used in municipal and industrial water treatment for coagulation, clarification, turbidity reduction, color removal, organic matter reduction, and sludge conditioning.
ACH has a high degree of neutralization and high polynuclear aluminum content. This helps destabilize fine suspended particles and colloidal impurities in raw water, allowing them to form larger flocs that can be removed through sedimentation, flotation, or filtration.
For drinking water applications, NSF 60 Certified ACH provides an important quality assurance for water treatment plants, engineering companies, and chemical distributors serving the potable water industry.
Key Benefits of NSF 60 Certified ACH
1. Suitable for Municipal Drinking Water Treatment
NSF 60 Certified Aluminum Chlorohydrate is designed for potable water treatment applications where chemical safety, consistency, and performance are important. It is suitable for municipal water treatment plants, surface water treatment systems, and drinking water clarification processes.
2. High Al2O3 Content
ACH contains a high level of Al2O3, which allows it to deliver strong coagulation performance at lower dosage levels compared with many conventional coagulants. This can help water treatment plants reduce chemical consumption and improve operational efficiency.
3. High Basicity
With high basicity, ACH has a lower impact on treated water pH. This is especially useful for drinking water treatment plants that want to maintain stable pH conditions and reduce the need for additional pH correction chemicals.
4. Broad pH Working Range
ACH performs effectively across a wider pH range than many traditional metal salt coagulants. This flexibility helps operators manage changing raw water conditions without frequent chemical adjustments.
5. Improved Turbidity and Color Removal
ACH can effectively remove suspended solids, colloidal particles, turbidity, and color-causing substances from raw water. It supports clearer treated water and improved filtration performance.
6. Supports TOC and Organic Matter Reduction
In addition to turbidity removal, ACH can help reduce certain organic matter and total organic carbon in the coagulation process. This is valuable for drinking water plants focusing on improved water quality and downstream treatment stability.

Main Applications
NSF 60 Certified Aluminum Chlorohydrate ACH is suitable for:
Typical Municipal Drinking Water Treatment Process
In a municipal drinking water plant, ACH is usually applied during the coagulation stage. The general process may include:
After ACH is added into raw water, it neutralizes the charge of suspended particles and colloids. During flocculation, these destabilized particles form larger and stronger flocs, which can then be removed more easily by sedimentation and filtration.

Powder and Liquid ACH Options
Bluwat Chemicals can supply both powder and liquid Aluminum Chlorohydrate for different plant requirements.
ACH powder is suitable for customers who prefer lower transportation volume, longer storage flexibility, and on-site solution preparation.
ACH liquid is suitable for water treatment plants that require convenient dosing, automatic chemical feeding, and easier handling in continuous treatment systems.
Both product forms are designed to provide stable coagulation performance for municipal water treatment and clarification.
Why ACH Is Used in Municipal Water Treatment
Municipal drinking water treatment plants need coagulants that can deliver stable results under variable raw water conditions. Rainfall, seasonal temperature changes, algae, silt, suspended solids, and organic matter can all affect coagulation performance.
ACH is selected because it offers:
For plants currently using alum or PAC, ACH can be considered a higher-performance coagulant option when lower dosage, better turbidity removal, or improved process stability is required.
