Understanding ACH: Key Properties and Handling for Water Treatment Professionals
For water treatment professionals, a deep understanding of the chemicals used is critical for successful plant operation, regulatory compliance, and cost management. Aluminum Chlorohydrate (ACH) is a highly effective inorganic polymer coagulant that offers significant advantages, but like any industrial chemical, understanding its key properties and proper handling procedures is essential. As a dedicated manufacturer and supplier of ACH, we are committed to providing professionals with the knowledge they need to utilize this powerful coagulant effectively and safely. When you are ready to buy ACH, partner with experts.
At its core, ACH is a group of water-soluble aluminum salts characterized by the general formula AlnCl3n−m(OH)m. Its defining features include a high concentration of Al2O3 (typically over 23%) and a high basicity (often 75-85%). This high basicity is a crucial differentiator, meaning the aluminum aggregates in ACH carry a more substantial positive charge. This enhanced cationic charge is what allows ACH to efficiently neutralize and destabilize negatively charged contaminants present in raw water, such as colloids, organic matter, and fine suspended particles. The result is the formation of robust, dense flocs that sediment rapidly, leading to superior turbidity removal and clearer treated water.
The handling and storage of ACH require adherence to standard chemical safety protocols. Typically supplied as a clear liquid, ACH is non-flammable and non-explosive. However, it is a mild acid and can be corrosive to certain materials. Therefore, appropriate storage tanks and piping systems should be used, often constructed from materials like fiberglass/epoxy, lined steel, polypropylene, or polyethylene. Schedule 80 PVC or polymer-lined piping is generally suitable. It is also important to consult the Safety Data Sheet (SDS) for specific guidance on personal protective equipment (PPE) such as gloves, eye protection, and protective clothing when handling ACH. Proper ventilation in storage and handling areas is also recommended.
The application of ACH in water treatment is straightforward. It can be added directly to the water stream, or diluted to a more manageable concentration, typically between 2-20% for liquid products. The exact dosage will depend on the raw water quality, temperature, and desired treatment outcome, often determined through jar testing. Its effectiveness across a wide pH range and its minimal impact on water alkalinity are significant operational advantages, often reducing the need for pH adjustment chemicals.
