NSF Standard 60 Aluminum Chlorohydrate for TOC Reduction in Drinking Water Plants
Product Overview
Bluwat Chemicals supplies NSF Standard 60 Aluminum Chlorohydrate for TOC reduction, natural organic matter control, and drinking water clarification. Aluminum Chlorohydrate, also known as Aluminum Hydroxychloride, Aluminum Chlorhydrol, or ACH, is a high-basicity aluminum-based coagulant widely used in municipal drinking water treatment plants.
In drinking water treatment, Total Organic Carbon, also known as TOC, is an important water quality parameter. TOC is often related to natural organic matter, color, odor potential, and the performance of downstream treatment processes. When raw water contains high organic matter, the coagulation process becomes more important for improving clarification efficiency and supporting stable treated water quality.
NSF Standard 60 Aluminum Chlorohydrate provides strong charge neutralization and efficient floc formation. It helps water treatment plants remove suspended solids, turbidity, color-causing substances, and part of the organic matter present in raw water.
What Is TOC in Drinking Water Treatment?
TOC means Total Organic Carbon. It represents the amount of carbon contained in organic compounds in water. In raw water sources such as rivers, lakes, and reservoirs, TOC may come from decomposed plants, algae, soil organic matter, agricultural runoff, wastewater influence, and seasonal biological activity.
High TOC in raw water may affect:
Water color and appearance
Coagulation performance
Filter operation
Disinfection process stability
Taste and odor control
Potential formation of disinfection by-products
Overall drinking water treatment efficiency
Coagulation is one of the common treatment steps used to reduce certain types of organic matter before filtration and disinfection. ACH can support this process by improving particle and organic matter removal.
What Is Aluminum Chlorohydrate ACH?
Aluminum Chlorohydrate is an inorganic polymer coagulant with the molecular formula Al2(OH)5Cl·2H2O. It has high Al2O3 content, high basicity, and active polymeric aluminum species.
When ACH is added to raw water, it neutralizes negatively charged particles, colloids, and organic matter complexes. These destabilized impurities can then form larger flocs during the flocculation stage. The flocs can be removed by sedimentation, clarification, flotation, or filtration.
Because ACH has high basicity, it usually has less impact on treated water pH than many conventional aluminum salts. This makes it useful for drinking water plants that need stable coagulation and pH control.
Key Benefits
NSF Standard 60 Certified
NSF Standard 60 Aluminum Chlorohydrate is suitable for drinking water treatment applications where certified coagulants are required. It supports municipal water plants, engineering companies, and chemical distributors serving potable water projects.
TOC & Organic Reduction
ACH can help reduce certain types of natural organic matter during the coagulation process. By improving floc formation, it supports the removal of organic particles, color-causing substances, and colloidal organic matter from raw water.
Color & Turbidity Removal
Raw water with organic matter often has color and turbidity problems. ACH helps remove suspended solids, colloidal particles, and color-causing impurities, improving treated water clarity.
High Al2O3 Content
With high Al2O3 content, ACH delivers strong coagulation performance and may reduce the required dosage compared with some lower-concentration coagulants.
High Basicity
The high basicity of ACH helps reduce pH depression during treatment. This is important for drinking water plants that need stable pH conditions and want to reduce additional chemical adjustment.
Filtration Stability
By removing more particles and organic matter during coagulation and clarification, ACH can help reduce the loading on downstream filters and support more stable filtration operation.
Main Applications
TOC reduction in drinking water plants
Natural organic matter control
Municipal drinking water treatment
Potable water clarification
Surface water purification
River water treatment
Lake water treatment
Reservoir water treatment
Color reduction
Turbidity removal
Suspended solids reduction
Filter load reduction
Water treatment plant optimization
Application in Drinking Water Plants
In drinking water treatment plants, ACH is normally applied in the coagulation stage. It may be dosed as liquid ACH or prepared from ACH powder into solution before use.
A typical process may include:
Raw water intake
ACH coagulant dosing
Rapid mixing
Flocculation
Sedimentation or clarification
Filtration
Disinfection
Clean water storage
During rapid mixing, ACH disperses quickly and reacts with suspended particles, colloids, and organic matter. During flocculation, these impurities form larger flocs. The flocs are then removed through clarification and filtration. This process helps reduce turbidity, color, and part of the organic matter before disinfection.

How ACH Helps TOC Reduction
TOC reduction by coagulation depends on the type of organic matter, raw water pH, alkalinity, coagulant dosage, mixing condition, and flocculation performance. ACH helps the process through charge neutralization and floc formation.
ACH may support TOC reduction by:
Destabilizing colloidal organic matter
Improving removal of organic particles
Reducing color-causing substances
Enhancing floc strength
Improving sedimentation performance
Reducing fine particle carryover to filters
Supporting better downstream treatment stability
The actual TOC reduction efficiency should be confirmed through jar testing and plant trials because raw water composition can vary greatly.
ACH for Surface Water with Organic Matter
Surface water sources often contain natural organic matter from vegetation, algae, soil, and seasonal biological activity. During warm seasons or after rainfall, organic matter levels may increase.
ACH is suitable for treating surface water with organic matter because it offers:
Strong coagulation performance
Broad pH adaptability
Good turbidity and color removal
Stable floc formation
Lower pH impact than many traditional aluminum salts
Compatibility with conventional clarification and filtration systems
For drinking water plants treating river water, lake water, or reservoir water, ACH can be used as part of a process optimization strategy to improve clarification and organic matter control.
Dosage and Jar Testing
The proper dosage of ACH for TOC reduction depends on raw water quality and treatment goals. Because organic matter characteristics differ from one water source to another, jar testing is strongly recommended.
General testing and operation guidance:
Test different ACH dosages using actual raw water
Observe floc formation and settling performance
Measure turbidity, color, pH, and TOC when possible
Evaluate treated water clarity after settling or filtration
Adjust dosage according to seasonal water changes
Avoid overdosing to prevent unnecessary chemical consumption
