Some Common Uses of Polyaluminium Chloride in Daily Life
Polyaluminium chloride is a chemical that we often come across in our daily lives, yet many people are still unaware of its specific functions and benefits. What exactly is polyaluminium chloride? What are its key characteristics? And how does it perform in practical applications? Let's take a closer look at some essential knowledge about this important compound!
First, let's explore the performance of polyaluminium chloride. It has several notable advantages over traditional coagulants like aluminum sulfate. For example, it produces higher quality purified water, with a cost reduction of 15-30%. It also forms flocs more quickly and settles faster, improving processing efficiency. Additionally, it has lower alkalinity, which reduces the need for additional alkali agents. It works effectively across a wide pH range (5.0–9.0), making it highly adaptable. It is less corrosive, offers better operational conditions, and dissolves more easily than aluminum sulfate. Moreover, it causes less salt increase during water treatment, which is beneficial for ion exchange processes and high-purity water production. Lastly, it performs well even in low-temperature conditions, outperforming other inorganic coagulants.
Next, there are two main forms of polyaluminium chloride: liquid and solid. The liquid form is convenient for direct use, easy to load and unload, and generally more cost-effective. However, it requires special transportation and storage, increasing logistics costs. On the other hand, the solid form is easier to transport and store without the need for tankers, but it must be diluted before use, which increases labor intensity.
In terms of application, polyaluminium chloride is widely used in various industries. It’s commonly used in municipal water supply and wastewater treatment, industrial water purification, and the recovery of valuable materials from industrial waste. It helps settle coal dust in coal washing wastewater, recovers starch in food processing, and treats a variety of industrial effluents such as dyeing, leather, fluorine-containing, heavy metal, oily, papermaking, mining, brewing, metallurgical, meat processing, and more. It’s also used in paper sizing, sugar refining, casting, fabric anti-wrinkle treatments, catalyst carriers, pharmaceuticals, cement setting, and cosmetic ingredients.
These are just some of the many applications of polyaluminium chloride. If you have any questions or need further information, feel free to contact us. At Huaquan, we're here to help you understand and utilize this versatile chemical effectively.
