Achieving optimal results in water treatment with Polyaluminum Chloride (PAC) hinges on determining the correct dosage. This process is critical for both treatment efficacy and cost management. For procurement professionals and R&D scientists, understanding how to optimize PAC dosage can significantly enhance operational efficiency. As a leading Polyaluminum Chloride manufacturer and supplier, we provide practical guidance to help you achieve the best outcomes.

The first step in optimizing PAC dosage is to conduct a jar test. This laboratory procedure simulates the coagulation and flocculation process under controlled conditions. By testing different concentrations of PAC against representative samples of your source water, you can observe the floc formation, settling speed, and clarity of the treated water. The goal is to find the lowest dosage that effectively removes turbidity, color, and other target contaminants. A standard recommendation is that when the turbidity of source water is between 100-500 mg/L, the dosage might range from 3-6 mg/L, but this is a general guideline and must be adjusted based on specific testing.

Several factors influence the ideal PAC dosage. These include the turbidity and chemical composition of the source water, the desired level of water quality, pH, temperature, and the presence of other treatment chemicals. For example, highly turbid water typically requires a higher PAC dosage than clearer water. Similarly, water with a high concentration of dissolved organic matter or specific ions may necessitate adjustments to the dosage or the use of a co-coagulant. When you plan to buy Polyaluminum Chloride, consider these variables.

Basicity and Al2O3 content of the PAC product itself also play a role in dosage requirements. Products with higher Al2O3 content may be effective at lower dosages due to their enhanced coagulating power. Our range of Polyaluminum Chloride products, from yellow to white grades, are formulated to offer flexibility in dosage optimization. As a manufacturer committed to customer success, we strongly advise performing these small-scale tests before implementing large-scale applications.

For businesses looking to buy Polyaluminum Chloride, remember that consistent quality from your supplier is key. By partnering with a reliable manufacturer like us, you ensure that the product's performance characteristics remain stable, making dosage optimization a more predictable process. We offer comprehensive technical support to assist you in performing these tests and determining the most cost-effective dosage for your specific water treatment needs.
