PAC-031 Yellow PAC Powder for Wastewater Coagulation
Product Overview
PAC-031 Yellow PAC Powder is an inorganic polymer coagulant designed for wastewater coagulation and industrial water clarification.
As a Polyaluminum Chloride powder, PAC-031 helps destabilize suspended solids, colloidal particles and fine impurities in wastewater. After dosing and mixing, these small particles can form larger flocs and separate from water through sedimentation, dissolved air flotation or filtration.
Industrial wastewater and municipal sewage often contain high turbidity, suspended solids, organic impurities, sludge particles and unstable colloids. PAC-031 is widely used in these systems because it provides practical coagulation performance and cost effective treatment for large volume wastewater applications.
Bluwat supplies PAC-031 as yellow spray dried powder in 25 kg bags, suitable for wastewater treatment plants, industrial users, contractors and water treatment chemical distributors.
Why PAC-031 Is Used for Wastewater Coagulation
Wastewater coagulation is an important step in many treatment systems. Without proper coagulation, fine suspended particles and colloids may remain stable in water and fail to settle efficiently.
PAC-031 helps break this stability. It neutralizes the surface charge of particles and allows them to gather into micro flocs. During slow mixing, the flocs become larger and easier to remove.
For industrial wastewater and sewage treatment, PAC-031 is often selected when the treatment target is turbidity removal, suspended solids reduction, sludge settling improvement and overall wastewater clarification.
It can be used alone as a coagulant or together with PAM flocculant for stronger floc formation and faster sedimentation.
Key Advantages
PAC-031 is suitable for large volume wastewater treatment where treatment cost and stable performance are both important.
PAC-031 is supplied as yellow PAC powder and is widely used in industrial wastewater, sewage treatment and general water clarification.
PAC-031 can help treat wastewater with high suspended solids, fine particles and cloudy appearance.
With basicity of 50–90%, PAC-031 offers flexible coagulation performance for different wastewater conditions.
PAC-031 helps fine particles and colloids form larger flocs, improving sedimentation and solid liquid separation.
PAC-031 is commonly used before PAM flocculant. PAC-031 starts coagulation, while PAM enlarges flocs and improves settling speed.
PAC-031 can be used in municipal sewage, industrial wastewater, textile wastewater, paper mill wastewater, mining wastewater, coal washing wastewater and food processing wastewater.
Bluwat supplies PAC-031 from factory production with 25 kg bag packaging, container loading service and technical support.

Main Applications
PAC-031 is widely used for industrial wastewater coagulation. It helps reduce turbidity, suspended solids, colloidal particles and fine impurities in wastewater.
PAC-031 can be applied in sewage treatment plants to improve floc formation, suspended solids removal and effluent clarification.
For wastewater with high turbidity and heavy suspended solids, PAC-031 helps improve particle aggregation and sedimentation.
PAC-031 can support coagulation and clarification in textile wastewater treatment. It is often used together with water decoloring agent and PAM flocculant.
PAC-031 helps remove fibers, fillers, suspended solids and fine particles from paper mill wastewater, supporting better sludge separation.
Mining wastewater often contains fine mineral particles and high suspended solids. PAC-031 helps these particles form 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 reuse.
PAC-031 supports pretreatment of food processing wastewater by reducing suspended solids and improving clarification before biological treatment.
For chemical wastewater with unstable colloids and mixed impurities, PAC-031 can 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 PAC-031 solution is added into wastewater, it disperses quickly under rapid mixing. The coagulant contacts suspended solids, colloids and fine particles in the wastewater.
During coagulation, PAC-031 neutralizes the 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 flocs are separated from water through sedimentation, dissolved air flotation or filtration.
Suggested Dosing Process
A common wastewater coagulation process using PAC-031 includes the following steps.
First, prepare PAC-031 powder solution with clean water.
Second, dose PAC-031 solution into wastewater under rapid mixing.
Third, allow PAC-031 to fully contact suspended solids and colloidal particles.
Fourth, adjust pH if necessary according to jar test results.
Fifth, 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 determined by jar testing. Wastewater type, turbidity, pH, suspended solids, color, organic content and treatment target can all affect the best dosage.
PAC-031 and PAM Combination
PAC-031 and PAM are commonly used together in wastewater treatment.
PAC-031 works as the coagulant. Its main function is to destabilize suspended solids and colloids, allowing them to form micro flocs.
PAM works as the flocculant. Its main function is to bridge micro flocs into larger flocs and improve settling speed.
The recommended dosing order is PAC-031 first and PAM second.
For wastewater with strong 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 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 yellow powder with Al2O3 content of at least 29% and a wider basicity range. It is commonly used for industrial wastewater, sewage treatment, high turbidity wastewater and cost effective coagulation.
For many wastewater treatment projects, PAC-031 is a practical option when the buyer needs stable treatment performance and competitive operating cost.
