NSF 60 Certified Aluminum Chlorhydrol for High Turbidity Raw Water Treatment
Product Overview
Bluwat Chemicals supplies NSF 60 Certified Aluminum Chlorhydrol for high turbidity raw water treatment, drinking water clarification, and municipal water purification systems. Aluminum Chlorhydrol, also known as Aluminum Chlorohydrate, Aluminum Hydroxychloride, or ACH, is a high-basicity aluminum-based coagulant designed to remove turbidity, suspended solids, fine particles, color, and organic matter from raw water.
High turbidity raw water is a common challenge for municipal water treatment plants, especially during rainy seasons, flood periods, river disturbance, construction runoff, and seasonal source water changes. Fine clay, silt, organic particles, and colloids can remain suspended in water and are difficult to remove by filtration alone.
NSF 60 Certified Aluminum Chlorhydrol provides strong coagulation performance, fast particle destabilization, and stable floc formation. It helps water treatment plants improve clarification efficiency and maintain treated water quality even when raw water turbidity changes quickly.
What Is Aluminum Chlorhydrol?
Aluminum Chlorhydrol is another commonly used name for Aluminum Chlorohydrate, a highly concentrated aluminum-based coagulant in the polyaluminum family. Its molecular formula is Al2(OH)5Cl·2H2O.
ACH contains active polymeric aluminum species that can neutralize negatively charged suspended particles and colloids in raw water. After charge neutralization, these fine particles combine into larger flocs during the flocculation process. The flocs can then be removed by sedimentation, clarification, flotation, or filtration.
Because Aluminum Chlorhydrol has high basicity and high Al2O3 content, it can provide strong coagulation performance with relatively low dosage and less pH impact compared with many conventional aluminum salts.
High Turbidity Raw Water Challenges
Raw water turbidity can increase sharply when surface water sources are affected by environmental changes. High turbidity may reduce treatment efficiency, increase filter backwashing frequency, and make it harder for water plants to maintain stable water quality.
Common causes of high turbidity raw water include:
Key Benefits
1. NSF 60 Certified for Drinking Water Treatment
NSF 60 Certified Aluminum Chlorhydrol is suitable for potable water treatment applications where certified drinking water chemicals are required. It is suitable for municipal water treatment plants, water utilities, and engineering projects handling high turbidity raw water.
2. Strong Turbidity Removal Performance
ACH effectively removes turbidity caused by suspended solids, silt, clay, fine particles, and colloidal impurities. It helps improve water clarity and supports stable downstream filtration.
3. High Al2O3 Content for Efficient Coagulation
Aluminum Chlorhydrol contains a high level of Al2O3, which provides strong active coagulation performance. This can help reduce dosage compared with lower-concentration coagulants.
4. High Basicity and Lower pH Impact
With high basicity, Aluminum Chlorhydrol has a lower tendency to reduce treated water pH. This is important for drinking water plants that need stable pH control during high turbidity events.
5. Fast Floc Formation
ACH can quickly destabilize fine particles and support the formation of larger flocs. Stronger flocs improve settling and clarification performance.
6. Suitable for Seasonal Turbidity Fluctuations
Raw water quality often changes by season. ACH provides broad pH adaptability and stable coagulation performance, making it useful for plants facing frequent turbidity variation.
Main Applications
NSF 60 Certified Aluminum Chlorhydrol is suitable for:
Application in High Turbidity Water Treatment
In high turbidity water treatment, Aluminum Chlorhydrol is usually dosed into the rapid mixing stage. Proper mixing ensures that the coagulant quickly contacts suspended particles and colloids.

Why ACH Works Well for High Turbidity Water
High turbidity raw water contains a large number of suspended particles. These particles usually carry negative charges and remain dispersed in water. Without effective charge neutralization, they are difficult to settle.
Dosage Optimization During High Turbidity Events
The required dosage of Aluminum Chlorhydrol depends on turbidity level, pH, alkalinity, water temperature, organic matter, and treatment process design. During high turbidity events, operators should adjust dosage based on jar testing and plant performance.
