PAC Powder Insoluble Matter ≤1.5% for Industrial Wastewater Treatment
Product Overview
PAC Powder Insoluble Matter ≤1.5% is a Polyaluminum Chloride water treatment chemical designed for industrial wastewater and sewage treatment applications.
In industrial wastewater treatment, the main treatment target is often to reduce turbidity, suspended solids, colloidal particles, sludge particles and fine impurities. These particles may remain stable in water and cannot settle efficiently without chemical coagulation.
PAC powder works as an inorganic polymer coagulant. After dosing and mixing, it helps neutralize the surface charge of fine particles and colloids. These particles then gather into larger flocs, which can be removed by sedimentation, dissolved air flotation or filtration.
Bluwat PAC-031 is a yellow spray dried PAC powder 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, municipal sewage, high turbidity wastewater and cost effective coagulation applications.
Why Insoluble Matter ≤1.5% PAC Is Used for Wastewater
For many industrial wastewater projects, the treatment system needs a balance between coagulation performance and operating cost.
PAC powder with insoluble matter ≤1.5% is suitable for wastewater systems where the water quality is relatively complex and the treatment volume is large. It can provide effective floc formation and turbidity removal while maintaining a practical cost level.
This grade is commonly used in sewage treatment plants, industrial effluent treatment systems, mining wastewater, coal washing wastewater, paper mill wastewater and high turbidity wastewater clarification.
For wastewater applications, PAC-031 is often selected when the user needs a cost effective yellow PAC powder for regular coagulation and sedimentation.
Key Advantages
PAC powder with insoluble matter ≤1.5% is suitable for large volume industrial wastewater and sewage treatment projects.
This PAC grade helps treat wastewater containing heavy suspended solids, sludge particles and fine colloidal impurities.
PAC powder destabilizes fine particles and supports the formation of larger flocs for easier separation.
PAC-031 has a basicity range of 50–90%, giving flexible performance for different wastewater treatment conditions.
PAC-031 is supplied as yellow spray dried powder and is widely used in wastewater and sewage treatment systems.
PAC can be used before PAM flocculant to improve floc size, settling speed and sludge separation.
It can be used in industrial wastewater, municipal sewage, textile wastewater, paper mill wastewater, mining wastewater and coal washing wastewater.
Bluwat supplies PAC powder directly from factory with 25 kg bag packaging, export loading service and technical support.

Main Applications
PAC powder insoluble matter ≤1.5% is widely used in industrial wastewater treatment to reduce turbidity, suspended solids, colloids and fine impurities.
PAC-031 can be used in municipal sewage treatment plants to improve coagulation, floc formation and effluent clarification.
For wastewater with high turbidity and high suspended solids, PAC powder helps improve particle aggregation and solid liquid separation.
Textile wastewater may contain color, suspended solids, organic matter and fine particles. PAC powder can be used together with water decoloring agent and PAM flocculant to improve clarification.
PAC helps remove fibers, fillers and fine suspended solids from paper mill wastewater, supporting better sedimentation and clearer effluent.
Mining wastewater often contains fine mineral particles and high suspended solids. PAC powder helps these particles form larger flocs for easier settling.
PAC-031 can support coal washing wastewater treatment by improving sedimentation of fine coal particles and reducing wastewater turbidity.
Food processing wastewater may contain organic residues, protein, starch, oil and suspended solids. PAC powder can be used as a coagulant for pretreatment and clarification.
For chemical wastewater with mixed colloids and process residues, PAC powder helps improve coagulation before sedimentation, DAF or filtration.
How PAC Powder Insoluble Matter ≤1.5% Works
-
PAC powder is normally dissolved in clean water before dosing.
-
After the prepared PAC solution is added into wastewater, it disperses under rapid mixing and contacts suspended solids, colloidal particles and fine impurities.
-
During chemical coagulation, PAC neutralizes the surface charge of these particles. Once the particles lose stability, they begin to gather and form micro flocs.
-
During slow mixing, the micro flocs grow into larger and heavier flocs. These flocs can then be removed by sedimentation, dissolved air flotation or filtration.
-
When PAM flocculant is added after PAC, the flocs can become larger, stronger and faster settling, improving wastewater clarification performance.
Suggested Dosing Process
A common wastewater treatment process using PAC powder insoluble matter ≤1.5% includes the following steps.
-
First, test wastewater quality, including pH, turbidity, suspended solids, color and treatment target.
-
Second, prepare PAC powder solution with clean water.
-
Third, dose PAC solution into wastewater under rapid mixing.
-
Fourth, allow PAC 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, color, organic content and treatment target can all affect the best dosage.
PAC and PAM Combination
PAC powder and PAM flocculant are commonly used together in industrial wastewater treatment.
PAC 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 order is PAC first and PAM second.
For wastewater with high color or stable dissolved pollutants, a water decoloring agent may be used before PAC depending on wastewater condition and jar test result.
PAC-031 Compared with Low Insoluble PAC Grades
PAC-01 is white powder with Al2O3 content of at least 30% and insoluble matter of no more than 0.1%. 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 commonly used for industrial wastewater, municipal wastewater and sewage treatment where lower insoluble matter is preferred.
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, high turbidity wastewater, sewage treatment and cost effective coagulation.
For large volume wastewater treatment projects where operating cost is important, PAC-031 is a practical choice.
