The safety of potable water is non-negotiable. Ensuring that water treatment chemicals are not only effective but also safe for human consumption is a primary concern for municipalities and water authorities worldwide. Polyaluminium Chloride (PAC) has gained significant traction in potable water treatment due to its efficacy and favorable safety profile compared to older coagulants. NINGBO INNO PHARMCHEM CO.,LTD. sheds light on why PAC is considered a safer choice.

Historically, aluminum sulfate (alum) has been widely used for potable water treatment. While effective, alum can contribute to higher levels of residual aluminum in treated water, and its use often requires careful pH adjustment to avoid issues like aluminum toxicity or increased corrosivity. Concerns about aluminum's potential links to health conditions, though largely unsubstantiated by robust scientific evidence for drinking water exposure, have led to a demand for coagulants that minimize aluminum residuals.

Polyaluminium Chloride (PAC) offers distinct advantages in this regard. As a more advanced coagulant, PAC often requires lower doses and exhibits a more efficient removal of impurities, including turbidity, color, and organic matter. Crucially, under optimized treatment conditions, PAC can lead to lower residual aluminum concentrations in the final potable water compared to alum. This enhanced performance contributes to meeting stringent drinking water standards and provides greater assurance regarding the safety of the treated water.

Furthermore, PAC's broad operating pH range simplifies the treatment process, reducing the need for extensive pH adjustments. This not only improves operational efficiency but also minimizes the potential for unintended chemical side effects that could impact water safety. When considering how to use polyaluminium chloride for potable water, adherence to recommended dosages and proper monitoring are key to maximizing its benefits and ensuring safety.

Compliance with international standards is a critical factor in the adoption of any water treatment chemical for potable water. Many PAC products conform to standards set by organizations like the American Water Works Association (AWWA) and meet criteria like NSF/ANSI 60 for drinking water chemicals. This adherence to strict quality and safety regulations underscores PAC's suitability for potable water applications. The market's preference for safe water treatment chemicals has driven the widespread adoption of PAC globally.

The ongoing research into polyaluminium chloride water treatment applications continues to validate its efficacy and safety. As a high efficiency inorganic coagulant, it offers a compelling combination of performance and peace of mind. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing potable water treatment facilities with high-quality PAC that meets rigorous safety standards, contributing to the delivery of safe and clean drinking water to communities.
