In the critical field of water treatment, selecting the correct coagulant is paramount to achieving efficient purification, meeting regulatory standards, and managing operational costs. While traditional coagulants like Polyaluminum Chloride (PAC) and aluminum sulfate (alum) have long been industry staples, Aluminum Chlorohydrate (ACH) is increasingly recognized for its advanced performance and inherent advantages. This article delves into why ACH stands out and why it's a compelling choice for many applications.

Understanding Coagulant Chemistry: The Role of Charge and Basicity

Coagulants work by neutralizing the negative charges of suspended particles and dissolved organic matter in water, causing them to aggregate into larger flocs. These flocs can then be more easily removed through sedimentation or filtration. The effectiveness of a coagulant is largely determined by its aluminum concentration and basicity – a measure of its acid neutralization capacity, reflecting how highly polymerized the aluminum is.

The Distinct Advantages of Aluminum Chlorohydrate (ACH)

ACH, a group of specific aluminum salts, offers a unique profile of benefits that set it apart:

1. Higher Aluminum Concentration and Basicity: ACH typically boasts the highest aluminum concentration (often exceeding 23% Al2O3 in liquid form) and basicity (around 80-85%) among commercially available aluminum-based solutions. This translates to a higher cationic charge, making it exceptionally effective at destabilizing and removing even very small suspended particles. Consequently, less dosage is required compared to PAC or alum to achieve similar or superior results.

2. Reduced Dosage and Cost Savings: The higher efficiency of ACH means you can use less product to treat the same volume of water. This leads to significant cost savings on chemical procurement, transportation, and storage. For businesses looking to buy Aluminum Chlorohydrate in bulk, these savings can be substantial.

3. Minimal Impact on pH: Due to its inherently high basicity, ACH has a negligible effect on the treated water's pH. This is a major advantage over other coagulants that often cause significant pH depression, requiring additional alkali (like soda ash) to adjust and stabilize the water. This not only simplifies the treatment process but also reduces the consumption of secondary chemicals.

4. Wide pH Range Adaptability: ACH performs effectively across a broad pH range, typically from 5 to 9.5. This versatility allows it to be used in diverse water sources and conditions without extensive pH adjustments, making it a reliable supplier for various operational needs.

5. Lower Sludge Production and Easier Dewatering: ACH forms denser, more compact flocs compared to traditional coagulants. This characteristic leads to a reduced volume of chemical sludge produced during the treatment process. Furthermore, the sludge generated by ACH typically dewaters more efficiently, further reducing handling and disposal costs.

6. Environmental Friendliness and Safety: ACH is considered an eco-friendly option due to its reduced sludge output and lower corrosiveness. It also contains very low levels of impurities, making it safe for drinking water applications and suitable for high-demand industrial processes. When you purchase ACH from a reputable manufacturer, you can be assured of its quality and safety compliance.

7. Versatile Applications: Beyond its primary use in drinking water and wastewater treatment, ACH is also utilized in the paper industry as a sizing agent and retention aid, and in cosmetics and pharmaceuticals. Its broad applicability makes it a valuable chemical across multiple sectors.
