PAC-02 Yellow Polyaluminum Chloride Powder for Industrial Wastewater
Product Overview
PAC-02 Yellow Polyaluminum Chloride Powder is an industrial water treatment coagulant designed for wastewater clarification and chemical coagulation.
Industrial wastewater often contains suspended solids, colloidal particles, fine impurities, organic matter, color bodies and process residues. These impurities can remain stable in water and are difficult to remove by natural settling alone.
PAC-02 helps destabilize these fine particles through coagulation. After dosing and mixing, suspended particles and colloids begin to form larger flocs. These flocs can then be removed by sedimentation, dissolved air flotation or filtration.
Bluwat PAC-02 is produced by spray drying technology and supplied as yellow powder. It offers stable Al2O3 content, low insoluble matter and reliable performance for industrial wastewater treatment and municipal wastewater clarification.
Why PAC-02 Is Suitable for Industrial Wastewater
Industrial wastewater quality is often more complex than drinking water or simple municipal sewage. Wastewater may come from textile dyeing, paper making, mining, food processing, chemical production, metal processing or mixed industrial sources.
PAC-02 is suitable for these applications because it provides strong coagulation performance and wide adaptability. It can help reduce turbidity, suspended solids and colloidal impurities. In many systems, it can also support color reduction and COD reduction when used together with other treatment chemicals.
For difficult wastewater, PAC-02 is commonly used before PAM flocculant. PAC-02 starts the coagulation process, while PAM helps enlarge the flocs and improve settling speed.
Key Advantages
PAC-02 contains at least 30% Al2O3, providing strong active content for industrial wastewater coagulation.
PAC-02 is supplied as yellow powder and is widely used for industrial wastewater, sewage treatment and general water clarification.
With insoluble matter of no more than 0.1%, PAC-02 provides good dissolution performance and stable dosing operation.
PAC-02 helps destabilize suspended solids and colloids, allowing fine particles to form larger flocs.
PAC-02 can reduce turbidity caused by fine particles, sludge particles and colloidal impurities in wastewater.
PAC-02 works well with PAM flocculant. PAC is added first for coagulation, and PAM is added later for stronger flocculation and faster sedimentation.
PAC-02 is suitable for textile, paper, mining, food processing, chemical, municipal and other industrial wastewater treatment systems.
Bluwat supplies PAC-02 directly from factory with stable quality, 25 kg bag packaging and export service.
Technical Specifications
Main Applications
PAC-02 is widely used for industrial wastewater clarification. It helps remove suspended solids, turbidity, colloids and fine impurities from wastewater.
Textile wastewater often contains color, turbidity, organic matter and suspended particles. PAC-02 can be used together with water decoloring agent and PAM flocculant to improve clarification performance.
PAC-02 helps remove fibers, fillers, suspended solids and fine particles from paper mill wastewater, supporting clearer effluent and better sludge separation.
Mining wastewater usually contains fine mineral particles and high suspended solids. PAC-02 helps improve particle aggregation and solid liquid separation.
PAC-02 can support treatment of coal washing wastewater by improving sedimentation of fine coal particles and reducing turbidity.
Food processing wastewater may contain organic matter, suspended solids, oil, protein and starch residues. PAC-02 can be used as a coagulant for pretreatment and clarification.
For chemical wastewater with unstable colloids and mixed impurities, PAC-02 helps improve coagulation before sedimentation, DAF or filtration.
PAC-02 can also be used in municipal wastewater plants for turbidity reduction, suspended solids removal and phosphorus removal support.
How PAC-02 Works in Wastewater Treatment
PAC-02 powder is normally dissolved in clean water before dosing.
After the PAC-02 solution is added into wastewater, it disperses quickly under rapid mixing. PAC-02 contacts suspended particles, colloids and fine impurities in the wastewater.
During coagulation, PAC-02 neutralizes the surface charge of these particles. Once the particles lose stability, they begin to form micro flocs.
During slow mixing, micro flocs grow into larger and stronger flocs. If PAM flocculant is added after PAC-02, the flocs can become bigger and settle faster.
Finally, the flocs are separated from water through sedimentation, dissolved air flotation or filtration.
Suggested Dosing Process
A common wastewater treatment process using PAC-02 includes the following steps.
The actual dosage should be confirmed by jar testing. Wastewater type, pH, turbidity, suspended solids, color, organic content and treatment target can all affect the best dosage.
PAC-02 and PAM Combination
PAC-02 and PAM are commonly used together in industrial wastewater treatment.
PAC-02 is the coagulant. It destabilizes suspended solids and forms micro flocs.
PAM is the flocculant. It bridges micro flocs into larger flocs and improves settling speed.
The recommended dosing sequence is PAC-02 first and PAM second.
For wastewater with high color or stable dissolved pollutants, a water decoloring agent may be used before PAC-02 depending on the wastewater condition.
PAC-02 Compared with Other PAC Grades
PAC-01 is white powder and is commonly used for drinking water treatment and high purity water applications.
PAC-02 is yellow powder with Al2O3 content of at least 30% and low insoluble matter. It is suitable for industrial wastewater, municipal wastewater and general clarification.
PAC-031 is also yellow powder and is often used for cost effective industrial wastewater and sewage treatment applications.
For many industrial wastewater projects, PAC-02 provides a good balance of performance, solubility and cost.
