PAC Powder Insoluble Matter ≤0.1% for Water Clarification
Product Overview
PAC Powder Insoluble Matter ≤0.1% is a Polyaluminum Chloride water treatment chemical designed for applications that require good dissolution, stable dosing and reliable clarification performance.
In water treatment, insoluble matter is an important quality indicator. Low insoluble matter means the PAC powder can dissolve more cleanly in water and produce a more stable dosing solution. This helps reduce residue in dosing tanks, pipelines and pumps, while supporting better contact between the coagulant and impurities in water.
Bluwat supplies low insoluble PAC powder grades including PAC-01 white powder and PAC-02 yellow powder. Both grades have insoluble matter of no more than 0.1% and Al2O3 content of at least 30%.
PAC-01 is commonly used for drinking water treatment and high clarity water purification. PAC-02 is commonly used for industrial wastewater treatment, municipal wastewater treatment, sewage treatment and general water clarification.
Why Low Insoluble Matter Is Important
Low insoluble matter is important for both water treatment performance and dosing system operation.
When PAC powder dissolves well, the prepared solution is more uniform and easier to dose. This helps the coagulant disperse quickly after entering raw water or wastewater.
If insoluble matter is too high, undissolved residue may remain in the solution tank or dosing line. This may affect dosing accuracy, increase cleaning frequency and reduce operation stability.
For drinking water treatment, low insoluble matter supports cleaner solution preparation and better clarification before filtration and disinfection.
For industrial wastewater treatment, low insoluble matter helps maintain stable chemical feeding and supports consistent coagulation results.
Key Advantages
PAC-01 and PAC-02 both have insoluble matter of no more than 0.1%, supporting clean dissolution and stable dosing operation.
With Al2O3 content of at least 30%, these PAC powder grades provide strong active content for coagulation and turbidity removal.
Low insoluble PAC powder dissolves well in water and can be prepared as a solution for continuous dosing systems.
PAC powder helps remove turbidity, suspended solids, colloids, clay particles, sludge particles and fine impurities.
After proper dosing and mixing, PAC powder helps fine particles form larger flocs for easier sedimentation, flotation or filtration.
PAC-01 can be used for drinking water clarification, while PAC-02 can be used for industrial wastewater and municipal wastewater treatment.
PAC powder can be used before PAM flocculant to improve floc size, settling speed and solid liquid separation.
Bluwat supplies PAC powder directly from factory with stable quality, 25 kg bag packaging and export service.
Recommended PAC Grades
PAC-01 is suitable for applications that require white powder, high purity and cleaner clarification.
PAC-02 is suitable for wastewater treatment applications that require strong coagulation performance and low insoluble matter.
Main Applications
PAC-01 white powder can be used in drinking water treatment plants to remove turbidity, suspended solids and colloids before filtration and disinfection.
Low insoluble PAC powder helps clarify river water, lake water, reservoir water and surface water by improving coagulation and floc formation.
PAC-01 supports potable water treatment where stable quality, good solubility and low residue are important.
PAC-02 yellow powder is suitable for industrial wastewater clarification, including textile wastewater, paper mill wastewater, mining wastewater, chemical wastewater and food processing wastewater.
PAC powder can be used in municipal wastewater plants to improve suspended solids removal, floc formation and effluent clarity.
PAC-02 helps sewage treatment systems improve coagulation, sedimentation and solid liquid separation.
In dissolved air flotation systems, PAC powder helps destabilize particles before flotation separation, especially when used with PAM flocculant.
PAC powder helps reduce fine particles before filtration, supporting smoother filtration operation and clearer treated water.
How PAC Powder Insoluble Matter ≤0.1% Works
Low insoluble PAC powder is normally dissolved in clean water before dosing.
After the prepared PAC solution is added into raw water or wastewater, it disperses quickly under rapid mixing. PAC contacts suspended solids, colloids and fine impurities in the water.
During chemical coagulation, PAC 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 and more visible flocs. These flocs can then be removed through sedimentation, dissolved air flotation or filtration.
When PAM flocculant is added after PAC, the flocs can become larger and settle faster, improving solid liquid separation.
Suggested Dosing Process
A common water clarification process using low insoluble PAC powder includes the following steps.
First, prepare PAC powder solution with clean water.
Second, dose the PAC solution into raw water or wastewater under rapid mixing.
Third, allow PAC to fully contact suspended solids and colloidal particles.
Fourth, adjust pH if necessary according to jar test results.
Fifth, continue slow mixing to support floc growth.
Sixth, add PAM flocculant if larger flocs and faster settling are required.
Finally, separate the formed flocs through sedimentation, DAF or filtration.
The actual dosage should be confirmed by jar testing. Water quality, pH, turbidity, suspended solids, organic matter, color and treatment target can all affect the best dosage.
PAC and PAM Combination
PAC powder and PAM flocculant are commonly used together in water and 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 sequence 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-01 and PAC-02 Selection Guide
Choose PAC-01 when the application is drinking water treatment, potable water treatment, raw water clarification or high purity water treatment.
Choose PAC-02 when the application is industrial wastewater treatment, municipal wastewater treatment, sewage treatment or general water clarification.
Both PAC-01 and PAC-02 have insoluble matter of no more than 0.1% and Al2O3 content of at least 30%. The final selection should be based on water quality, treatment target, local requirements, dosage cost and jar test results.
