NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of providing advanced chemical solutions for water treatment, and our Polyferric Sulfate (PFS) consistently proves to be a superior alternative to traditional coagulants such as aluminum sulfate (alum) and ferric chloride. Understanding these differences highlights why PFS is increasingly the preferred choice for both municipal and industrial applications, including its use in PFS for drinking water purification.

One of the most significant advantages of PFS lies in its performance across a wider pH range. Traditional coagulants are often highly sensitive to pH fluctuations, necessitating precise pH control and the addition of corrective chemicals. PFS, however, remains effective in a broader pH spectrum, typically from 4 to 10, simplifying the treatment process and reducing operational complexity. This inherent stability is a key factor in its reliable performance in various water chemistries.

When it comes to efficiency, PFS generally requires a lower dosage to achieve the same or better results compared to alum or ferric chloride. This reduced chemical consumption directly translates into lower treatment costs, a critical consideration for any large-scale water treatment operation. Furthermore, the flocs formed by PFS are typically denser and more stable, leading to faster sedimentation and improved solids removal. This enhanced settling characteristic aids downstream processes like filtration, leading to higher effluent quality and greater throughput.

Environmental considerations also favor PFS. While traditional iron and aluminum salts can introduce residual contaminants into treated water or cause significant pH drops, PFS is known for its lower residual iron content and a less corrosive nature. This makes it a safer option for both the environment and the treatment infrastructure. The ability of PFS to effectively remove a wide array of pollutants, including heavy metals, COD, and BOD, further underscores its advantage in comprehensive water purification. For anyone looking at industrial wastewater treatment or general water clarity, the comparative advantages of PFS are clear.
