Achieving optimal results in water treatment with Polyaluminum Chloride (PAC) hinges critically on correct dosage. As a leading supplier of PAC, we understand that improper dosing can lead to inefficient treatment, increased costs, or even compromised water quality. This guide provides essential insights into determining and applying the right PAC dosage for your industrial applications.

The optimal dosage of PAC is not a one-size-fits-all parameter. It is influenced by several factors, including the raw water's turbidity, pH, temperature, and the specific contaminants present. For instance, water with higher turbidity or a greater organic load will typically require a higher PAC dosage to achieve effective flocculation and clarification.

The most reliable method for determining the correct PAC dosage is through a jar test. This laboratory procedure involves treating small samples of the raw water with varying concentrations of PAC. By observing the floc formation, settling speed, and clarity of the treated water, you can identify the dosage that yields the best results for your specific water source. We recommend performing these tests regularly, especially if raw water quality fluctuates.

When preparing to buy Polyaluminum Chloride, consider its form—powder or liquid—as this can affect how it's dosed. Solid PAC is usually dissolved in water to create a stock solution, which is then further diluted before application. The concentration of this solution and the injection rate into the water stream are critical for consistent performance. For industrial procurement, working with a supplier that offers technical support for dosage optimization can be invaluable.

The goal is to use the minimum amount of PAC necessary to achieve the desired water quality. Overdosing can lead to wasted product and potential issues like residual aluminum in treated water. Underdosing, conversely, results in ineffective treatment. By carefully determining and applying the correct PAC dosage, you can maximize the benefits of this efficient coagulant, ensuring cost-effectiveness and high-quality water treatment outcomes.
