White Powder Solid Poly Aluminium Chloride (PAC)
Poly Aluminium Chloride (PAC), also known as Aluminium Chloride Hydroxide, is a water-soluble, inorganic polymer with the general chemical formula [Al2(OH)nCl6-n]m. It is widely used due to its simplicity, broad range of applications, low cost, and high efficiency in water treatment and various other industries.
PAC is a water treatment agent that destabilizes the colloids in wastewater, causing them to aggregate.
PAC is typically supplied as a solution or powder. Its powdered form makes transportation and storage easier while reducing the volume required for use. The production process of powdered PAC utilizes advanced spray drying technology.
PAC is a pre-hydrolyzed coagulant composed of aluminum, hydroxide, and chloride. The -OH groups are responsible for the Basicity in PAC, and the high positive charge density on aluminum makes it a powerful destabilizer for negatively charged suspended impurities in water. This property makes PAC more cationic than alum, providing superior results.
The white solid poly aluminium chloride produced by this company, with a 30% concentration and medium Basicity, is labeled as PAC-W30. It contains a minimum of 28% Al2O3 and has a Basicity range of 40% to 50%.
White PAC is produced through a different process compared to yellow PAC and is manufactured in separate reactors. Additionally, liquid white PAC is transformed into this solid white product (PAC-W30) using the company’s dedicated drying tower.
This product is obtained by drying the liquid white PAC using the company’s specialized drying tower, making it an excellent choice for turbidity removal from water. It is offered by the company for potable water treatment and wastewater applications.
The product specifications, based on laboratory results, meet standard requirements and are provided as follows:
Storage and Handling:
PAC should be stored at moderate temperatures in a dry and well-ventilated area. It must be kept in sealed and closed containers as much as possible, protecting it from physical damage and freezing. Under no circumstances should it be subjected to thermal decomposition, as it can produce hazardous decomposition products such as hydrochloric acid and aluminum oxides.
Advantages of Using White Solid Poly Aluminium Chloride (PAC) 30% (PAC-W30)
The white solid poly aluminium chloride produced by this company, with its high positive charge, delivers more efficient coagulation and turbidity removal even at much lower doses compared to alum and ferric chloride. Additionally, it forms denser sludge, resulting in less sludge volume.
This coagulant works by neutralizing the negative charge of suspended particles and colloids, causing the precipitation of turbidity-causing materials in water. Due to its superior sedimentation performance and the formation of larger flocs, PAC performs much more effectively in coagulation and flocculation than conventional coagulants like ferric chloride and alum.
This polymeric chemical leaves behind much less aluminum in the water compared to other common aluminum-based coagulants, making it highly beneficial for human health and environmental protection.
Its dosage, with a pH between 3.5 to 5, is so low that it has no significant impact on the pH of the water. It maintains its high performance efficiency over a wide range of pH and temperature conditions.
Compared to alum, PAC can use longer molecular chains and a much higher electric charge in solution for separation and treatment. Additionally, it maximizes the physical coagulation process, providing better coagulation with PAC, especially in waters with medium to high turbidity.
Overall, PAC has numerous advantages over aluminum sulfate in the process, including:
– Reduced coagulant dosage
– Effective performance over a wider range of raw water pH
– Higher sedimentation rate of produced flocs
– Reduced filtration cycles
– Reduced consumption of coagulant aids
Applications of White Solid Poly Aluminium Chloride (PAC) 30% (PAC-W30)
This product, PAC-W30, is highly effective for turbidity removal and water clarification, with strong coagulation and flocculation capabilities. It is also widely used in industrial water treatment and wastewater treatment in various chemical, petrochemical, and pharmaceutical industries. Furthermore, it finds applications in papermaking, leather processing, cosmetics, food industries, cement, paints, textiles, and more.
