Effective water treatment hinges on the precise application of chemical coagulants like Polyaluminium Chloride (PAC). As a leading manufacturer and supplier of PAC in China, we understand that optimizing dosage and application methods is critical for achieving desired water quality while managing costs. This guide delves into the practical aspects of using PAC to ensure maximum efficiency for your operations.

The first step in determining the correct dosage of Polyaluminium Chloride is always a jar test. This laboratory procedure allows you to simulate the coagulation process using your specific raw water source. By testing various concentrations of PAC, you can identify the optimal dosage that effectively removes turbidity, color, and other contaminants while minimizing chemical usage. Factors such as water temperature, pH, alkalinity, and the nature of the pollutants will influence the ideal PAC dosage, which typically ranges from a few parts per million (ppm) to tens of ppm for solid PAC, and higher for liquid formulations. Remember, more is not always better; overdosing can lead to residual aluminum issues or ineffective treatment.

When applying PAC, consider its form – whether solid powder or liquid solution. Solid PAC is usually dissolved in water to create a solution of a specific concentration (commonly 5-20%) before being introduced into the water stream. It’s advisable to prepare the solution in a dedicated tank and use it within 24 hours, as its effectiveness can diminish over time. Liquid PAC is often ready for direct dosing or dilution as per the manufacturer's recommendations. The method of introduction is also important; PAC should be mixed rapidly with the raw water to ensure thorough dispersion and contact with the contaminants. This is followed by a period of slow mixing to promote flocculation, allowing the formation of larger, settleable flocs.

Maintaining the correct pH is another crucial aspect of PAC application. While PAC is effective over a broad pH range (typically 5-9), optimizing the pH for your specific water conditions can significantly enhance coagulation performance. If your water is highly acidic or alkaline, minor adjustments might be necessary, but PAC generally requires less pH adjustment than traditional coagulants like alum, contributing to its cost-effectiveness. Always refer to the technical data sheet provided by your PAC supplier for specific guidance on pH management and optimal application parameters.
