Polyaluminum Chloride Coagulant Powder for Industrial Wastewater Treatment
Product Overview
Polyaluminum Chloride Coagulant Powder, also known as PAC powder, is an inorganic polymer coagulant widely used in industrial wastewater treatment. It is designed to improve coagulation, floc formation and solid liquid separation in different wastewater treatment processes.
Industrial wastewater often contains suspended solids, colloids, organic matter, color bodies, fine particles and other contaminants. These pollutants can remain stable in water and are difficult to remove by simple sedimentation. PAC powder helps destabilize these impurities and allows them to form larger flocs during the coagulation and flocculation process.
Bluwat PAC powder is produced by spray drying technology. It has stable quality, good solubility and strong adaptability to different wastewater conditions. It can be used alone as a coagulant or together with PAM flocculant to improve sedimentation, clarification and sludge separation.
Why PAC Powder Is Used for Industrial Wastewater
Industrial wastewater quality is often unstable. The pH, turbidity, color, suspended solids and organic load may change depending on production process, raw materials and discharge conditions.
PAC powder is widely used because it can quickly react with suspended particles and colloids. After dosing, PAC neutralizes the electrical charge on these particles and promotes the formation of micro flocs. During slow mixing, the flocs become larger and heavier, making them easier to settle or separate.
For many wastewater treatment plants, PAC is used as the main coagulant before PAM flocculant. PAC starts the coagulation process, while PAM helps enlarge the flocs and improve sedimentation speed. This combination is commonly used in industrial wastewater clarification, DAF systems, sedimentation tanks and sludge treatment processes.
Key Advantages
PAC powder provides efficient charge neutralization and helps form stable flocs in industrial wastewater. It is suitable for wastewater with suspended solids, colloids and fine particles.
The flocs formed after PAC dosing can settle faster under proper mixing and dosing conditions. This helps improve clarification efficiency and reduce treatment time.
PAC can be used in many industrial wastewater systems, including textile, paper, mining, chemical, food processing, metallurgical and municipal industrial wastewater.
PAC powder helps reduce turbidity and TSS by aggregating fine particles into larger flocs that are easier to remove.
In some industrial wastewater, PAC can help reduce color and organic impurities, especially when used together with decoloring agents and PAM flocculants.
PAC and PAM are commonly used together in wastewater treatment. PAC works as the coagulant, while PAM works as the flocculant to strengthen floc size and settling performance.
With proper jar testing and dosage optimization, PAC powder can help reduce chemical consumption and improve treatment efficiency.
Typical Industrial Wastewater Applications
Textile wastewater usually contains color, suspended solids, surfactants and organic matter. PAC powder can be used as a coagulant to improve color removal, turbidity reduction and solid liquid separation. In difficult dyeing wastewater, it is often used after a water decoloring agent and before PAM flocculant.
Paper mill wastewater may contain fibers, fillers, suspended solids and organic impurities. PAC can help improve clarification, reduce turbidity and support sludge separation in paper wastewater treatment systems.
Mining and mineral processing wastewater often contains fine suspended solids and mineral particles. PAC powder helps improve particle aggregation and solid liquid separation, supporting clearer overflow water and better sedimentation.
Coal washing wastewater contains fine coal particles and high suspended solids. PAC can be used as a coagulant to improve settling performance and support water recycling.
Food processing wastewater may contain organic matter, suspended solids, oil and protein residues. PAC can support coagulation and clarification before biological treatment or final sedimentation.
Chemical industrial wastewater can contain complex impurities and unstable colloids. PAC powder helps destabilize particles and improve pretreatment performance before further treatment steps.
For industrial wastewater entering municipal treatment systems, PAC can help reduce turbidity, suspended solids and phosphorus load, supporting more stable plant operation.
Recommended PAC Grades for Industrial Wastewater
Bluwat supplies different PAC powder grades for different treatment needs.
For most industrial wastewater treatment applications, PAC-02 and PAC-031 are commonly selected based on water quality, treatment target and cost requirements.
Suggested Treatment Process
A typical industrial wastewater treatment process using PAC powder can be arranged as follows.
First, check wastewater pH, turbidity, color, suspended solids and treatment target.
Second, prepare PAC powder into a solution with clean water.
Third, add PAC solution into wastewater under rapid mixing to ensure full contact with particles and colloids.
Fourth, adjust pH if necessary according to the wastewater type and coagulation performance.
Fifth, add PAM flocculant solution under slow mixing to enlarge flocs and improve sedimentation.
Finally, allow flocs to settle or separate through sedimentation, flotation or filtration.
The exact dosage should be determined by jar testing. Different wastewater sources may require different PAC dosage, PAM type and pH conditions.
PAC and PAM in Wastewater Treatment
PAC and PAM are often used together but they have different functions.
PAC is a coagulant. Its main role is to neutralize particle charge and destabilize suspended solids and colloids.
PAM is a flocculant. Its main role is to bridge small flocs into larger flocs and improve settling speed.
For industrial wastewater treatment, the usual sequence is PAC first and PAM second. If wastewater contains high color or stable dissolved pollutants, a water decoloring agent or other pretreatment chemical may also be used before PAC.
Packaging and Storage
Bluwat PAC powder is supplied in 25 kg bags with inner plastic bag and outer woven bag.
The product should be stored in a cool, dry and well ventilated place. Keep away from moisture, heat and direct sunlight. Keep the bags sealed when not in use.
Proper storage helps maintain stable product performance and prevents moisture absorption during long term storage.
