Spray Dried PAC-031 Powder for Industrial Wastewater Treatment
Product Overview
Spray Dried PAC-031 Powder is a Polyaluminum Chloride water treatment chemical designed for industrial wastewater treatment and wastewater coagulation.
It is supplied as yellow powder and produced by spray drying technology. The powder form is convenient for storage, transportation, export shipment and solution preparation before dosing.
Industrial wastewater often contains suspended solids, colloidal particles, fine impurities, sludge particles, organic matter and process residues. These pollutants may remain stable in water and cannot be removed efficiently by natural settling alone.
PAC-031 works as an inorganic polymer coagulant. After dosing and mixing, it helps destabilize suspended particles and colloids. These small particles then form larger flocs, which can be removed by sedimentation, dissolved air flotation or filtration.
Bluwat supplies PAC-031 spray dried powder in 25 kg bags for industrial wastewater treatment plants, municipal sewage treatment plants, contractors and water treatment chemical distributors.
What Is Spray Dried PAC-031 Powder
Spray dried PAC-031 powder is made from Polyaluminum Chloride solution through spray drying technology. This process converts liquid PAC into stable dry powder under controlled production conditions.
PAC-031 is a yellow powder grade with Al2O3 content of at least 29%, basicity of 50–90% and insoluble matter of no more than 1.5%.
It is commonly used for industrial wastewater treatment, municipal sewage treatment, high turbidity wastewater and cost effective coagulation applications.
Compared with drinking water grade PAC, PAC-031 is mainly selected for wastewater systems where stable clarification performance and competitive operating cost are important.
Why PAC-031 Is Used for Industrial Wastewater Treatment
Industrial wastewater quality can vary greatly depending on the production process. Textile dyeing, paper making, mining, coal washing, food processing, chemical production and metal processing wastewater may all contain different levels of turbidity, suspended solids, color, organic matter and colloidal impurities.
PAC-031 helps improve the first stage of clarification by chemical coagulation. It Roller-neutralizes the surface charge of fine particles and makes them easier to gather into flocs.
After proper coagulation and flocculation, wastewater can be clarified more efficiently in sedimentation tanks, DAF units or filtration systems.
For many industrial wastewater projects, PAC-031 is a practical option because it provides reliable coagulation performance with a cost effective treatment profile.
Key Advantages
PAC-031 is produced by spray drying technology and supplied as stable yellow powder. It is easy to pack, store, transport and dissolve before use.
PAC-031 is suitable for large volume industrial wastewater and sewage treatment projects where operating cost is an important factor.
With basicity of 50–90%, PAC-031 can adapt to different wastewater conditions and treatment requirements.
PAC-031 helps reduce turbidity caused by suspended solids, colloids, fine particles and sludge particles.
After proper dosing and mixing, PAC-031 helps fine particles form visible flocs for easier sedimentation or flotation.
PAC-031 is commonly used for wastewater with high suspended solids and cloudy appearance.
PAC-031 is often used before PAM flocculant. PAC-031 starts coagulation, while PAM improves floc size, settling speed and sludge separation.
Bluwat supplies spray dried PAC-031 powder directly from factory with 25 kg bag packaging, container loading service and technical support.

Main Applications
Spray dried PAC-031 powder is widely used in industrial wastewater treatment to reduce turbidity, suspended solids, colloids and fine impurities.
PAC-031 can be used in sewage treatment plants to improve coagulation, floc formation and suspended solids removal.
For wastewater with high turbidity and heavy suspended solids, PAC-031 helps improve particle aggregation and solid liquid separation.
Textile wastewater may contain color, turbidity, suspended solids and organic matter. PAC-031 can be used together with water decoloring agent and PAM flocculant to improve clarification performance.
PAC-031 helps remove fibers, fillers, suspended solids and fine particles from paper mill wastewater, supporting clearer effluent and better sludge separation.
Mining wastewater often contains fine mineral particles and high suspended solids. PAC-031 helps these particles gather into larger flocs for easier settling.
PAC-031 can be used in coal washing wastewater treatment to improve sedimentation of fine coal particles and support water recycling.
Food processing wastewater may contain organic matter, protein, starch, oil and suspended solids. PAC-031 can be used as a coagulant for pretreatment and clarification.
For chemical wastewater with unstable colloids and mixed impurities, PAC-031 helps improve coagulation before sedimentation, DAF or filtration.
How PAC-031 Works in Wastewater Treatment
PAC-031 powder is normally dissolved in clean water before dosing.
After the prepared PAC-031 solution is added into wastewater, it disperses quickly under rapid mixing. PAC-031 contacts suspended solids, colloidal particles and fine impurities in the wastewater.
During chemical coagulation, PAC-031 neutralizes the surface charge of these particles. Once the particles lose stability, they begin to form micro flocs.
During slow mixing, the micro flocs grow into larger flocs. If PAM flocculant is added after PAC-031, the flocs can become larger, stronger and faster settling.
Finally, the formed flocs are separated from water through sedimentation, dissolved air flotation or filtration.
Suggested Dosing Process
A common industrial wastewater treatment process using spray dried PAC-031 powder includes the following steps.
First, test wastewater quality, including pH, turbidity, suspended solids, color and treatment target.
Second, prepare PAC-031 powder solution with clean water.
Third, dose PAC-031 solution into wastewater under rapid mixing.
Fourth, allow PAC-031 to fully contact suspended solids and colloidal particles.
Fifth, adjust pH if necessary according to jar test results.
Sixth, add PAM flocculant under slow mixing if larger flocs and faster sedimentation are required.
Finally, separate the formed flocs through sedimentation, DAF or filtration.
The actual dosage should be confirmed by jar testing. Wastewater source, pH, turbidity, suspended solids, organic content, color and treatment target can all affect the best dosage.
PAC-031 and PAM Combination
PAC-031 and PAM are commonly used together in industrial wastewater treatment systems.
PAC-031 works as the coagulant. It destabilizes suspended solids and colloids and forms micro flocs.
PAM works as the flocculant. It bridges micro flocs into larger flocs and improves settling speed.
The recommended dosing sequence is PAC-031 first and PAM second.
For wastewater with high color or stable dissolved pollutants, a water decoloring agent may be used before PAC-031 depending on wastewater condition and jar test result.
PAC-031 Compared with PAC-01 and PAC-02
PAC-01 is white powder with Al2O3 content of at least 30% and low insoluble matter. It is commonly used for drinking water treatment and high purity water clarification.
PAC-02 is yellow powder with Al2O3 content of at least 30% and insoluble matter of no more than 0.1%. It is suitable for industrial wastewater, municipal wastewater and general clarification.
PAC-031 is yellow powder with Al2O3 content of at least 29% and insoluble matter of no more than 1.5%. It is commonly used for industrial wastewater, sewage treatment, high turbidity wastewater and cost effective coagulation.
For industrial wastewater projects where treatment cost and stable coagulation performance are both important, PAC-031 is a practical choice.
