Poly aluminum chloride (PAC) is one of those super - useful chemicals that many industries can't do without. As a supplier of poly aluminum chloride, I've seen firsthand how it's used in a bunch of different ways. In this blog, I'll break down the main uses of PAC so you can get a better idea of why it's such a big deal.
Water Treatment
One of the most well - known uses of poly aluminum chloride is in water treatment. Whether it's for drinking water, industrial wastewater, or sewage treatment, PAC plays a crucial role.
In drinking water treatment, the goal is to make water safe and clean for human consumption. PAC acts as a coagulant. When it's added to water, it neutralizes the electrical charges of suspended particles. These particles, which are usually very small and can be difficult to remove on their own, start to clump together. This process is called coagulation. Once the particles form larger clumps, or flocs, they can be easily removed through sedimentation or filtration. This helps to get rid of impurities like dirt, bacteria, and some heavy metals, making the water clear and safe to drink.
For industrial wastewater, different industries produce different types of pollutants. For example, the mining industry might have high levels of heavy metals in its wastewater, while the food processing industry could have a lot of organic matter. PAC can be customized to deal with these specific pollutants. It helps to separate the contaminants from the water, allowing the treated water to be reused in the industrial process or safely discharged into the environment.
Sewage treatment also relies heavily on PAC. In sewage plants, large amounts of human waste and other organic materials need to be removed. PAC helps to coagulate these materials, making them easier to settle out. This reduces the load on the subsequent treatment processes and helps to produce cleaner effluent.

Paper Making
The paper - making industry is another major consumer of poly aluminum chloride. In paper production, PAC has several important functions.
First, it's used as a sizing agent. Sizing is the process of making paper resistant to liquids, especially water. When PAC is added to the paper pulp, it reacts with the cellulose fibers in the pulp. This forms a thin layer on the surface of the fibers, which helps to prevent water from penetrating the paper. This is crucial for making high - quality paper, such as printing paper and packaging paper, as it improves the paper's strength, printability, and resistance to ink spread.
Secondly, PAC helps in the retention and drainage of the paper pulp. In the paper - making process, the pulp contains a lot of water that needs to be removed. PAC helps to flocculate the fine particles in the pulp, allowing the water to drain more easily. At the same time, it also helps to retain the fine fibers and fillers in the paper, which improves the paper's quality and reduces waste.

Textile Industry
In the textile industry, PAC is used for dyeing and printing processes. During the dyeing process, it helps to fix the dyes onto the fabric. The positively charged PAC molecules interact with the negatively charged dye molecules, forming a stable complex. This ensures that the dye is evenly distributed on the fabric and has good color fastness. In other words, the color won't fade easily when the fabric is washed or exposed to sunlight.
PAC is also used in the treatment of textile wastewater. Textile manufacturing generates a large amount of wastewater that contains dyes, chemicals, and other pollutants. PAC can coagulate these pollutants, making them easier to remove from the water. This helps the textile industry to meet environmental regulations and reduce its impact on the environment.
Oil and Gas Industry
The oil and gas industry also makes use of poly aluminum chloride. In oilfield water treatment, produced water is a by - product of oil and gas extraction. This water contains various contaminants such as oil, suspended solids, and salts. PAC can be used to separate the oil from the water. It coagulates the oil droplets and suspended solids, allowing them to be removed through sedimentation or filtration. This helps to recycle the water for further use in the oilfield operations or to safely dispose of it.
In the gas processing industry, PAC can be used to treat the wastewater generated during the gas purification process. It helps to remove impurities and contaminants from the water, ensuring that the treated water meets the environmental standards.
Construction Industry
In the construction industry, PAC can be used as an additive in concrete. When added to concrete, it can improve the workability of the concrete mixture. It helps to reduce the water content required for a given level of workability, which in turn increases the strength of the concrete. PAC also has a retarding effect on the setting time of concrete. This can be useful in large - scale construction projects where it's necessary to control the hardening time of the concrete.
Other Uses
There are also some other minor but still important uses of poly aluminum chloride. For example, in the pharmaceutical industry, PAC can be used in the purification of some drugs. It helps to remove impurities and clarify the drug solutions.
In the cosmetic industry, PAC can be used in some formulations as an astringent. It has the ability to constrict the pores on the skin, which can be beneficial for some skin - care products.
