Poly Aluminium Chloride (PAC) is widely used across various industries due to its strong coagulating, flocculating, and water treatment properties. Below are the industries that commonly use PAC:
- Water Treatment Industry
- Municipal Drinking Water Treatment: PAC is extensively used in water purification plants to clarify drinking water. It acts as a coagulant, removing suspended particles, turbidity, and organic matter.
- Wastewater Treatment: PAC is used in the treatment of both industrial and municipal wastewater. It helps in removing heavy metals, phosphates, oils, and suspended solids, making the water safer for discharge or reuse.
- Swimming Pool Water Treatment: It is used to coagulate impurities and enhance the clarity of pool water.
- Paper Industry
- Paper Production: PAC is used in the papermaking process as a retention aid and sizing agent. It improves paper strength, enhances the retention of fillers and fibers, and helps with the smoothness of the paper surface.
- Effluent Treatment: Paper mills often use PAC to treat their wastewater before disposal, ensuring that the discharge meets environmental standards.
- Textile Industry
- Dyeing and Finishing: In the textile industry, PAC is used in dyeing processes to help the dye bind better to fabrics and achieve uniform coloration. It can also be used in the wastewater treatment process to remove color, solids, and other pollutants.
- Effluent Treatment: Textile mills use PAC to treat effluents that contain dyes, chemicals, and other waste materials, reducing environmental pollution.
- Oil and Gas Industry
- Enhanced Oil Recovery: PAC is used in oil drilling operations to clarify drilling water, allowing for smoother operations. It is also used to treat wastewater generated from oil and gas exploration and refining processes.
- Mining and Metallurgy Industry
- Mineral Processing: PAC is used in mining to treat water used in mineral processing, particularly to remove suspended particles, making the water suitable for reuse or discharge.
- Metal Precipitation: It helps in the separation of metals and removal of heavy metals from wastewater streams in metallurgical processes.
- Food and Beverage Industry
- Water Purification: In food and beverage production, PAC is used to purify process water and treat wastewater. It’s often utilized for its ability to remove contaminants without adding harmful by-products, making it ideal for applications where water quality is critical.
- Pharmaceutical Industry
- Process Water Treatment: PAC is used in the pharmaceutical industry for treating process water and wastewater, ensuring that it meets the stringent requirements for purity and cleanliness.
- Chemical Industry
- Industrial Effluent Treatment: PAC is used to treat industrial effluents, including in chemical plants, to remove solids, oils, and other impurities before discharging the wastewater.
- Tanning and Leather Industry
- Wastewater Treatment: PAC is used in the leather tanning process, particularly in treating wastewater generated from the tannery. It helps in the removal of suspended solids, fats, and oils from the effluent, ensuring compliance with environmental regulations.
- Construction Industry
- Concrete Admixture: PAC can be used as an additive in the preparation of concrete mixtures to improve the strength and durability of the concrete, particularly in high-performance applications.
- Cosmetics and Personal Care Industry
- Cosmetic Formulations: In some personal care products, PAC is used as a coagulant or stabilizer in emulsions, though this is a less common application compared to its primary industrial uses.
- Sugar Refining Industry
- Sugar Clarification: PAC is used in sugar mills during the clarification process, where it helps remove impurities and suspended solids from sugar juice, ensuring a clearer and purer final product.
- Dye and Pigment Industry
- Dye Production: In the production of dyes and pigments, PAC is used to treat wastewater and improve the efficiency of dye binding to fabrics or materials. It helps reduce color and chemical contaminants from effluents.
PAC is prized for its effectiveness as a coagulant in both water treatment and industrial processes, offering a reliable and economical solution for improving water quality and removing pollutants from various streams.
