Why is polyaluminium ferric chloride more effective than traditional water purifiers?
Publish Time: 2025-07-03
In the water treatment industry, polyaluminium ferric chloride (PAFC) liquid products have become important agents in the fields of sewage treatment, industrial circulating water purification, drinking water treatment, etc. due to its efficient coagulation performance, wide adaptability and excellent treatment effect. As a new type of high-efficiency inorganic polymer flocculant, it combines the advantages of polyaluminium chloride and polyferric sulfate, and shows excellent performance in removing suspended matter, organic matter, heavy metal ions and decolorization in water. It is gradually replacing traditional aluminum salt or iron salt products and is widely used in municipal, chemical, printing and dyeing, papermaking and other industries.The biggest advantage of polyaluminium ferric chloride is its efficient and stable coagulation ability. The product has a large specific surface area and strong electrical neutralization and adsorption bridging effects. It can quickly condense colloidal particles and tiny impurities in water to form large and dense alum flowers with fast sedimentation speed and high treatment efficiency. Compared with traditional aluminum sulfate or ferric chloride, PAFC uses less and forms a smaller volume of sludge, thereby reducing the cost of subsequent sludge treatment.Secondly, polyaluminium ferric chloride has a wide range of applicability and is suitable for treatment needs under different water quality conditions. Whether it is low-temperature and low-turbidity water, high-turbidity surface water, or complex water such as oily wastewater and printing and dyeing wastewater, polyaluminium ferric chloride can play a good purification role. In particular, it can still maintain good results under a wide pH range (5-11), making it stable in various water treatment scenarios and reducing the additional investment required to adjust water quality.From the perspective of environmental protection and safety, polyaluminium ferric chloride liquid products are packaged in polyethylene barrels with good sealing performance, easy to transport and store, and not easy to leak and pollute the environment. Although this product is corrosive to a certain extent, as long as it is operated in accordance with the specifications and avoids mixing with other chemicals, the use process can be ensured to be safe and controllable. At the same time, since it does not contain heavy metal ions that are harmful to the environment, the treated effluent will not cause secondary pollution, which is in line with the development direction of green water treatment.In addition, polyaluminium ferric chloride has a long shelf life, which can be stored for 6 months in liquid form and up to 12 months in solid form, providing users with a sufficient application window. Even if stored in a humid environment, it will not affect its use effect, enhancing the flexibility and stability in practical applications. For enterprises that need long-term storage or bulk purchases, this feature greatly improves the convenience and economy of use.It is worth mentioning that polyaluminium ferric chloride also has significant advantages in reducing operating costs. Due to its small dosage and high treatment efficiency, the unit water treatment cost is significantly lower than that of traditional agents. At the same time, the precipitated sludge formed is easy to dehydrate, which reduces the cost of sludge disposal and improves the overall operating efficiency. This is an extremely attractive choice for modern water treatment companies that pursue energy saving, consumption reduction, quality improvement and efficiency enhancement.With its core advantages such as high-efficiency coagulation, wide applicability, safety and environmental protection, convenient storage and transportation, and cost control, polyaluminium ferric chloride (liquid) has become one of the indispensable important agents in the current water treatment industry. Whether in urban sewage treatment plants, industrial wastewater treatment projects, or rural water supply projects, it demonstrates strong market competitiveness and technical value.
