Low Insoluble PAC Powder for Drinking Water Clarification
Product Overview
Low Insoluble PAC Powder is a high quality Polyaluminum Chloride powder designed for drinking water clarification and high clarity water treatment applications.
In drinking water treatment, chemical purity and dissolution quality are very important. A PAC powder with low insoluble matter can dissolve more cleanly in water and support stable dosing performance. This helps water treatment plants achieve more reliable coagulation, floc formation and turbidity removal.
Bluwat PAC-01 is a white Polyaluminum Chloride 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, raw water clarification and potable water purification.
After dosing into raw water, PAC powder helps destabilize suspended solids, clay particles, colloids and fine impurities. These particles then form larger flocs and can be removed through sedimentation, flotation or filtration.
Why Low Insoluble Matter Is Important
For drinking water clarification, low insoluble matter is an important quality indicator.
If a coagulant contains too much insoluble material, it may affect dissolution, increase residue, cause dosing system deposits and reduce treatment stability. In drinking water plants, this can create extra operation pressure and may influence final clarification performance.
Low insoluble PAC powder dissolves more easily and helps produce a cleaner dosing solution. This supports smoother chemical feeding, better contact with raw water impurities and more stable floc formation.
For applications that require cleaner water treatment chemicals, PAC-01 white powder is often preferred.
Key Advantages
Low Insoluble Matter
PAC-01 has insoluble matter of no more than 0.1%, supporting cleaner dissolution and stable operation in drinking water treatment systems.
High Al2O3 Content
With Al2O3 content of at least 30%, PAC powder provides strong active content for effective coagulation and turbidity removal.
White Powder Grade
PAC-01 is supplied as white powder and is suitable for drinking water clarification and high purity water treatment requirements.
Good Solubility
The spray dried PAC powder dissolves well in water and can be prepared as a dosing solution for continuous water plant operation.
Effective Turbidity Removal
PAC powder helps remove turbidity caused by suspended solids, clay particles, colloids and fine impurities in raw water.
Strong Floc Formation
After proper dosing and mixing, PAC helps fine particles form visible and compact flocs for easier sedimentation and filtration.
Stable Clarification Performance
Low insoluble PAC powder supports consistent coagulation performance and helps improve water clarity before filtration and disinfection.
Factory Direct Supply
Bluwat supplies PAC powder directly from factory with stable quality, 25 kg bag packaging and export support.

Main Applications
Drinking Water Clarification
Low insoluble PAC powder is used in drinking water treatment plants to clarify raw water before filtration and disinfection. It helps reduce turbidity and suspended solids.
Raw Water Treatment
PAC powder can be applied to river water, lake water, reservoir water and surface water sources that contain clay particles, algae, colloids and fine impurities.
Potable Water Purification
When selected and used according to local treatment requirements, low insoluble PAC powder supports potable water treatment by improving coagulation and clarification performance.
Surface Water Clarification
Surface water quality can change due to rainfall, seasonal conditions and upstream activity. PAC powder helps stabilize clarification by improving particle aggregation.
Low Turbidity Water Treatment
In low turbidity raw water, fine particles can be difficult to settle. PAC powder helps destabilize these particles and improve floc formation.
Seasonal High Turbidity Water
During rainy seasons or raw water quality fluctuations, PAC can help reduce turbidity load and support stable filtration operation.
High Purity Industrial Water Pretreatment
Low insoluble PAC powder can also be used in some industrial water pretreatment systems where cleaner dissolution and high clarity are required.
How Low Insoluble PAC Powder Works
Low insoluble PAC powder is normally dissolved in clean water before dosing.
After the prepared PAC solution is added into raw water, it disperses quickly under rapid mixing. PAC contacts suspended solids, colloids, clay particles and fine impurities.
During the coagulation stage, 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 flocs. These flocs can then settle in a sedimentation tank or be removed by filtration.
This process helps reduce turbidity, improve water clarity and protect downstream filtration and disinfection systems.
Suggested Dosing Process
A common dosing process for drinking water clarification includes the following steps.
First, prepare PAC powder solution with clean water.
Second, dose the PAC solution into raw water under rapid mixing.
Third, allow PAC to fully contact suspended solids and colloidal particles.
Fourth, continue slow mixing to support floc growth.
Fifth, allow the formed flocs to settle in the sedimentation tank.
Finally, send the clarified water to filtration and disinfection.
The actual dosage should be confirmed by jar testing. Raw water turbidity, pH, alkalinity, water temperature, organic matter and treatment target can all affect the best dosage.
PAC Powder and Filtration Performance
Good coagulation before filtration is important for drinking water treatment.
If fine particles and colloids are not removed properly before filtration, filter media may become overloaded and filtration efficiency may decrease. This can lead to shorter filter runs and less stable treated water clarity.
Low insoluble PAC powder helps form larger and more removable flocs before filtration. This can reduce fine particle load entering the filter and support more stable plant operation.
Low Insoluble PAC Compared with General PAC Grades
PAC-01
PAC-01 is white powder with Al2O3 content of at least 30% and insoluble matter of no more than 0.1%. It is commonly recommended for drinking water clarification and high purity water treatment.
PAC-02
PAC-02 is yellow powder with Al2O3 content of at least 30% and insoluble matter of no more than 0.1%. It is widely used for industrial wastewater, municipal wastewater and general water treatment.
PAC-031
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 and cost effective coagulation.
For drinking water clarification, PAC-01 is usually selected when white powder appearance, low insoluble matter and high purity are required.
