What are the characteristics of White Polyaluminium Chloride in sewage treatment?

Hello! I’m a supplier of white polyaluminium chloride (WPAC), a highly effective water treatment agent widely recognized in the industry. In this blog, I’ll share with you the unique characteristics of white polyaluminium chloride in sewage treatment based on my years of experience in the field. White Polyaluminium Chloride

High Purity and Low Impurity Content

One of the most prominent features of white polyaluminium chloride is its high purity. Unlike other polyaluminium chloride products, white polyaluminium chloride is made from high – quality raw materials and undergoes a refined production process. The content of aluminum oxide (Al₂O₃) in white polyaluminium chloride can reach more than 30%, and it has extremely low impurity content, especially the content of heavy metals such as iron, lead, and mercury.

In sewage treatment, this high – purity characteristic makes white polyaluminium chloride perform outstandingly. When treating drinking water or high – standard industrial water, the low impurity content ensures that the water quality after treatment meets strict safety and hygiene standards. For example, in the treatment of drinking water sources, the low heavy – metal content in white polyaluminium chloride avoids the secondary pollution of water, which is crucial for ensuring the health of the public.

Excellent Coagulation Performance

Coagulation is a key step in sewage treatment, and white polyaluminium chloride has excellent coagulation performance. It can quickly hydrolyze in water to form a variety of hydroxo – aluminum complexes with positive charges. These complexes can neutralize the negative charges on the surface of suspended particles and colloids in sewage, reducing the electrostatic repulsion between particles and making them easier to aggregate.

Compared with traditional coagulants such as ferric chloride and aluminum sulfate, white polyaluminium chloride can form larger and denser flocs in a shorter time. The large flocs settle quickly, which can effectively separate suspended solids from water, improving the sedimentation efficiency of sewage treatment. In addition, the flocs formed by white polyaluminium chloride have strong adsorption capacity, which can adsorb some dissolved organic matter and heavy metal ions in sewage while removing suspended particles, further improving the water quality.

Wide Applicability to Different Water Qualities

White polyaluminium chloride has a wide range of applicability to different water qualities. Whether it is high – turbidity sewage, low – turbidity sewage, acidic sewage, or alkaline sewage, white polyaluminium chloride can play a good role in treatment.

For high – turbidity sewage, the strong coagulation ability of white polyaluminium chloride can quickly reduce the turbidity of water, making the water clear. In the treatment of low – turbidity sewage, it can still effectively remove fine suspended particles and colloids, improving the clarity of water. When dealing with acidic or alkaline sewage, white polyaluminium chloride has a certain buffer capacity. It can adjust the pH value of water to a certain extent during the coagulation process, and maintain a relatively stable treatment effect in a wide pH range (usually pH 5 – 9).

Low Residual Aluminum in Treated Water

In sewage treatment, the residual amount of aluminum in the treated water is an important issue. Excessive residual aluminum in water may have potential negative impacts on human health and the environment. White polyaluminium chloride has a significant advantage in this regard.

Due to its high purity and good coagulation performance, white polyaluminium chloride has a relatively low residual amount of aluminum in the treated water compared with other polyaluminium chloride products. During the treatment process, most of the aluminum in white polyaluminium chloride participates in the coagulation reaction and forms flocs, which are removed by sedimentation or filtration. This characteristic makes white polyaluminium chloride more suitable for applications where strict control of residual aluminum is required, such as the treatment of drinking water.

Good Stability

White polyaluminium chloride has good stability, both in terms of physical and chemical properties. Physically, it is a white powder or granular solid at normal temperature, which is easy to store and transport. It will not easily deliquesce or agglomerate under normal storage conditions, ensuring its quality and performance.

Chemically, white polyaluminium chloride has a stable chemical structure. It can maintain its activity and coagulation performance for a long time, even when stored for a certain period. This stability makes it a reliable choice for sewage treatment plants. They can purchase white polyaluminium chloride in large quantities and store it for future use without worrying too much about the degradation of its performance over time.

Environmental Friendliness

In today’s era of increasing environmental awareness, the environmental friendliness of water treatment agents is highly valued. White polyaluminium chloride is an environmentally friendly water treatment agent. As mentioned above, its low heavy – metal content and low residual aluminum in treated water reduce the potential pollution to the environment.

In addition, the production process of white polyaluminium chloride is relatively clean and energy – efficient. With the continuous improvement of production technology, the energy consumption and waste emissions in the production process have been effectively controlled. When used in sewage treatment, it can help sewage treatment plants meet the increasingly strict environmental protection requirements, making it an ideal choice for sustainable water treatment.

Cost – effectiveness

Although the price of white polyaluminium chloride may be relatively higher than some ordinary polyaluminium chloride products, its high efficiency in sewage treatment makes it cost – effective in the long run.

Due to its excellent coagulation performance, a relatively small amount of white polyaluminium chloride can achieve the same or better treatment effect compared with other coagulants. This means that less dosage is required in sewage treatment, reducing the cost of chemicals. At the same time, the fast sedimentation speed of flocs formed by white polyaluminium chloride shortens the treatment time, improves the treatment efficiency of sewage treatment plants, and reduces the operating cost.

In conclusion, white polyaluminium chloride has many unique characteristics in sewage treatment, including high purity, excellent coagulation performance, wide applicability, low residual aluminum, good stability, environmental friendliness, and cost – effectiveness. These characteristics make it a preferred choice for various sewage treatment applications, from drinking water treatment to industrial wastewater treatment.
