Water treatment plays a crucial role in ensuring the cleanliness and safety of industrial and municipal water supplies. Polyaluminum chloride (PAC) is one of the most effective and widely used coagulants for water purification. Globex Venture specializes in supplying high-quality PAC to meet the diverse needs of customers worldwide.   What is Polyaluminum Chloride (PAC)? Polyaluminum chloride (PAC) is an inorganic polymer coagulant and one of the most effective coagulants currently available, efficiently removing suspended solids, organic matter, and pollutants from water. Its formulation involves partially neutralizing aluminum chloride, forming a polymer structure that enhances its coagulation properties.   PAC is available in both liquid and powder forms, making it versatile for various applications. Its chemical formula varies depending on the degree of polymerization and basicity.   Advantages of PAC in Water Treatment 1. High Coagulation Efficiency Compared to traditional coagulants like aluminum sulfate (alum), PAC has a higher charge density, making it more effective in destabilizing and aggregating suspended particles.   2. Wider pH Range Compatibility Unlike alum, PAC is effective over a wider pH range (4-10), reducing the need for pH adjustment and additional chemicals.   3. Reduced Sludge Formation Due to its high coagulation efficiency, PAC produces less sludge, lowering disposal costs and environmental impact.   4. Lower Dosage Requirements PAC requires lower dosages compared to traditional coagulants, resulting in cost savings for large-scale water treatment plants.   5.

Polyaluminum chloride is available in two colors: white and yellow.   Polyaluminum chloride is a highly effective water treatment chemical.  As a coagulant, it extracts and aggregates pollutants, colloids, and suspended solids. This leads to the formation of flocs, which can then be removed by filtration.   Polyaluminum chloride products used in water treatment are typically characterized by their basicity (%). Basicity refers to the ratio of hydroxyl ion concentration to aluminum ion concentration. Higher basicity means lower aluminum content, resulting in better removal of pollutants. Lower aluminum content is also beneficial to the process flow, as aluminum residue is significantly reduced.   Differences between Polyaluminum Chloride and Aluminum Sulfate Coagulants Aluminum sulfate has been a widely used coagulant in the water treatment industry for many years. It is used as a flocculant to remove pollutants, unwanted color, and general turbidity (haze) from water.   However, this process leaves a significant amount of aluminum residue in the water supply, requiring further filtration and generating a large amount of sludge-like waste (called water treatment residue), which is ultimately disposed of in landfills. These disposal costs directly impact the operating costs of water treatment plants, making it necessary to find alternatives that can reduce these costs.   While the waste treatment residue does possess many physical and chemical properties that could allow it to be used for more sustainable purposes, including as building materials or even soil nutrients, concerns about the toxicity of aluminum in soil and its detrimental effects on ecosystems have been well documented, limiting this approach.   On the other hand, polyaluminum chloride (PAC) has been developed as an alternative. PAC is more easily hydrolyzed, provides better coagulation, and has a faster flocculation rate, making it a more efficient product. Furthermore, it uses less aluminum, resulting in significantly reduced aluminum residue and sludge waste.   **Available Colors of Polyaluminum Chloride**   1. White Polyaluminum Chloride (PAC)   This is a newly developed water purification material specifically designed for food, drinking water, municipal water supply, precision manufacturing water purification, paper industry, pharmaceuticals, sugar refining, cosmetic additives, daily chemical industry, and many other fields. It has a very wide range of applications, is of very high purity, and is the most expensive. 3. Yellow Polyaluminum Chloride (PAC)   This is currently the most widely used polyaluminum chloride on the market. It is a highly effective flocculant suitable for wastewater treatment, offering excellent flocculation results. Therefore, it is the best choice for industrial water supply, industrial wastewater treatment, industrial water recycling, and municipal sewage treatment.

PAC Characteristics:   Yellow or brown granules or powder, easily soluble in water, readily absorbs moisture from the air, and is a novel, highly efficient inorganic polymer flocculant.   Applications:   This product is mainly used for drinking water purification and industrial wastewater treatment, such as industrial wastewater from industries like plasma papermaking and dyeing, municipal sewage, radioactive wastewater, and wastewater containing lead (Pb), chromium (Cr), and fluorine (F). It can also be used in precision casting, papermaking, and leather processing.   Usage Method:   Before use, dissolve the product in water to prepare a 5-10% solution, then dilute to the required concentration. Stirring is essential during dissolution, and the material should be added gradually. The diluted solution must be used within 24 hours; otherwise, hydrolysis will occur, reducing its effectiveness. Coagulation and sedimentation experiments can be conducted based on wastewater turbidity and the condition of the purification equipment to determine the optimal dosage.

Flocculants play a crucial role in modern water treatment processes, especially in wastewater and industrial effluent systems. A flocculant is a chemical agent that destabilizes suspended and colloidal particles in water, allowing them to aggregate into larger flocs that can be removed by sedimentation or flotation. In water treatment, flocculants are widely used to improve solid–liquid separation efficiency. When a flocculant is added to water, it interacts with charged particles and disrupts their natural stability. Through mechanisms such as electric double layer compression and charge neutralization, the dispersed particles begin to lose stability. Proper mixing during water treatment increases collision frequency, enabling impurities to form microflocs and later grow into visible flocs. In practical water treatment applications, flocculants are often combined with controlled stirring and reaction time to achieve optimal clarification results. Understanding how a flocculant functions is the first step toward selecting the right solution for different water treatment challenges.

Polyaluminum Chloride (PAC) is widely recognized as a high-performance coagulant in water treatment and wastewater treatment systems. Compared with conventional aluminum-based chemicals, PAC offers several operational and economic advantages that make it a preferred choice for industrial and municipal applications. One of the main advantages of polyaluminum chloride is its high coagulation efficiency at relatively low dosage. This allows treatment plants to reduce overall chemical consumption while maintaining excellent removal of suspended solids and colloidal particles, leading to lower operating costs. Polyaluminum Chloride PAC contains polymerized aluminum complexes that promote rapid and stable floc formation. The resulting flocs are denser and easier to separate through sedimentation or filtration, improving treatment efficiency and process reliability. Polyaluminum chloride performs effectively across a broad pH range, making it suitable for different types of industrial wastewater. In many cases, pH adjustment is minimal or unnecessary, simplifying system operation and reducing additional chemical use. Polyaluminum Chloride PAC typically results in lower residual aluminum concentrations in treated water. This helps facilities comply with strict environmental regulations and improves the overall safety and quality of the effluent.

Polyferric sulfate is a reliable inorganic polymer coagulant for water purification systems, valued for its strong aggregation ability and fast settling performance. Known for forming compact flocs, Polyferric sulfate helps remove suspended particles, color, and organic impurities efficiently, resulting in clearer treated water. The material is typically supplied as a yellow to reddish-brown solid that dissolves readily, allowing operators to prepare stable treatment solutions suitable for a wide range of water conditions. Across municipal and industrial applications, Polyferric sulfate demonstrates consistent results in turbidity reduction, phosphorus removal, and overall contaminant control. It has adaptable pH operating range and high charge density, Polyferric sulfate enhances particle destabilization and supports faster clarification compared to many traditional coagulants. It is commonly used in drinking water processing, industrial effluent treatment, and sewage management, where improved sludge compaction and easier dewatering are additional advantages. Beyond operational efficiency, Polyferric sulfate is also recognized for its cost-effectiveness and environmental compatibility. Lower dosage requirements and reduced residual impact make Polyferric sulfate an appealing alternative for facilities seeking to balance performance with sustainability goals. As treatment standards continue to rise, the demand for dependable coagulants like Polyferric sulfate is expected to grow, supporting cleaner water outcomes across diverse sectors.

As a byproduct of biological wastewater treatment, wastewater treatment plants (WWTPs) inevitably generate large amounts of wastewater sludge (WAS), posing a significant challenge. WAS is a typical solid waste that can easily cause secondary pollution if not properly treated. Typically, WAS treatment and disposal costs account for as much as 60% of the total operating costs of a wastewater treatment plant. However, WAS is rich in organic matter such as proteins and carbohydrates, making it a renewable bioenergy resource. WAS is commonly used for anaerobic digestion to produce methane. Short-chain fatty acids (SCFAs) are intermediate products of anaerobic digestion, including acetic acid, propionic acid, isobutyric acid, n-butyric acid, isovaleric acid, and n-valeric acid. Therefore, the production of SCFAs from sludge fermentation has attracted increasing attention in recent years, as the resulting SCFAs are not only a preferred carbon source for biological nitrogen and phosphorus removal but also raw materials for microbial production of biodegradable plastics.   Due to the low sludge decomposition rate and rapid consumption by methanogenic bacteria, the yield of SCFAs from wastewater sludge (WAS) fermentation is usually low. Therefore, previous studies have mostly focused on promoting SCFA production by accelerating sludge decomposition or inhibiting the activity of methanogens. Literature reports that various WAS pretreatment methods, such as enzymatic, free nitrite, thermal, Fenton, ozone, and ultrasonic pretreatment [9][10][11], as well as the operating conditions of anaerobic reactors (e.g., acid and alkaline control) [9], can effectively increase SCFA production. For example, pretreatment of waste activated sludge (WAS) with free nitrite (1.54–1.80 mg/L) for 2 days significantly enhances sludge disintegration, thereby increasing short-chain fatty acid (SCFA) production by 1.5–3.7 times [12]. Furthermore, increasing certain organic matter in fermentation sludge, such as carbohydrates and intracellular polyhydroxyalkanoates (PHAs), can also promote SCFA production.   Polyaluminum chloride (PAC) is an inorganic coagulant produced by the partial hydrolysis of an acidic aluminum chloride solution in a specific reactor. PACs are typically composed of aluminum monomers (such as Al³⁺, Al(OH)₂⁺, etc.), dimers (Al₂O₃), trimers (Al₃O₄), and inert macromolecular polymers with molecular weights typically greater than 3000 Da[18]. The chemical forms of hydrolyzed aluminum can be classified into three categories based on their reaction rates with iron indicators: monomers (Ala) (instantaneous reactions, i.e., aluminum monomers, dimers, and trimers), medium-rate polymers (Alb) (reaction within 120 minutes, i.e., Al₂O₃), and sols or gels (Alc) (non-reactive, i.e., aluminum polymers with molecular weights typically greater than 3000 Da). Under certain conditions, when a large amount of highly charged polynuclear aluminum hydrolysis products (Alb) are present, PACs are superior to traditional aluminum-based coagulants (such as AlCl3 and alum) in removing particulate matter and/or organic matter. Since the 1980s, polyphosphate precipitates (PACs) have been widely used in water and wastewater treatment worldwide for the removal of fine particles and heavy metals, precipitation of phosphates, and inactivation of viruses. During wastewater treatment, PACs are inevitably absorbed and concentrated by sludge, leading to their accumulation in large quantities within the sludge. The PAC content in sludge is highly dependent on the water source and other chemicals used, and varies significantly across different regions.

Polyaluminum Chloride (PAC) is a highly efficient coagulant widely used in water and wastewater treatment. Compared with traditional aluminum salts, Polyaluminum Chloride PAC delivers better performance with lower chemical consumption, making it a cost-effective solution for industrial and municipal applications. Polyaluminum Chloride PAC works effectively at low dosage and forms fast, dense flocs that are easy to separate by sedimentation or filtration, improving overall treatment efficiency. In addition, it performs well over a wide pH range, often reducing the need for pH adjustment. Due to its high reactivity, Polyaluminum Chloride PAC also results in lower residual aluminum levels in treated water, helping meet environmental standards and ensuring stable, reliable water quality.
