Polyaluminum Chloride Powder CAS 1327-41-9 for Water Treatment
Product Overview
Polyaluminum Chloride Powder CAS 1327-41-9, also known as PAC powder or Poly Aluminium Chloride powder, is a widely used water treatment coagulant.
It is designed to improve coagulation, floc formation and solid liquid separation in different water and wastewater treatment systems. After dosing into water, PAC helps destabilize suspended solids, colloidal particles and fine impurities. These small particles then gather into larger flocs and can be removed through sedimentation, flotation or filtration.
Bluwat supplies spray dried Polyaluminum Chloride powder in different grades, including PAC-01, PAC-02 and PAC-031. These grades are used for drinking water purification, municipal wastewater treatment, industrial wastewater clarification and other water treatment applications.

What Is Polyaluminum Chloride CAS 1327-41-9
Polyaluminum Chloride is an aluminum based inorganic polymer coagulant. CAS 1327-41-9 is commonly used to identify this chemical product in technical documents, product specifications, safety data sheets and international trade.
In water treatment, Polyaluminum Chloride works mainly as a coagulant. It neutralizes the surface charge of suspended particles and colloids, allowing them to combine and form larger flocs.
Compared with traditional coagulants such as aluminum sulfate, PAC powder can often provide faster floc formation, better sedimentation and wider adaptability to different water qualities.
Why Use PAC Powder for Water Treatment
Water treatment systems often need to remove turbidity, suspended solids, colloids, organic matter and fine particles. Many of these impurities are too small to settle naturally.
PAC powder helps improve this process through chemical coagulation. It makes fine particles unstable and easier to aggregate. Once larger flocs are formed, the water becomes easier to clarify.
PAC powder can be used in drinking water plants, sewage treatment plants, industrial wastewater facilities, DAF systems, sedimentation tanks and filtration pretreatment systems.
Key Advantages
PAC powder provides strong charge neutralization and helps fine particles form larger flocs for easier removal.
After proper dosing and mixing, PAC can quickly react with suspended solids and colloids, supporting faster clarification.
Spray dried PAC powder dissolves well in water and can be prepared as a dosing solution for continuous treatment operation.
Polyaluminum Chloride CAS 1327-41-9 can be used for drinking water, municipal wastewater, industrial wastewater, paper, textile, mining, coal washing and food processing wastewater.
Bluwat supplies white and yellow PAC powder grades to meet different purity, performance and cost requirements.
PAC is commonly used before PAM flocculant. PAC starts coagulation, while PAM enlarges the flocs and improves settling speed.
PAC powder is supplied in 25 kg bags, suitable for storage, container loading and export supply.
Bluwat provides stable PAC powder quality, technical support and export service for global water treatment customers.
Product Grades and Specifications
The suitable PAC grade should be selected according to water quality, turbidity, pH, treatment target and customer application.
Main Applications
PAC-01 white powder can be used for raw water clarification in drinking water treatment plants. It helps remove turbidity, suspended solids and colloidal particles before filtration and disinfection.
PAC powder supports chemical coagulation in sewage treatment plants. It helps reduce turbidity, suspended solids and phosphorus load, improving effluent clarity.
PAC-02 and PAC-031 are widely used in industrial wastewater clarification. They help remove fine particles, colloids, organic impurities and suspended solids.
For textile and dyeing wastewater, PAC can support color reduction, turbidity removal and floc formation when used with decoloring agent and PAM flocculant.
PAC powder helps remove fibers, fillers and suspended solids from paper mill wastewater and supports sludge separation.
PAC improves solid liquid separation in mining wastewater and coal washing wastewater by aggregating fine mineral particles and suspended solids.
PAC can be applied in food processing wastewater pretreatment to reduce suspended solids and improve clarification efficiency.
How PAC Powder Works
Suggested Dosing Process
A typical PAC treatment process includes the following steps.
The actual dosage should be confirmed by jar testing. Water quality, pH, turbidity, suspended solids, temperature and treatment target can all affect the best dosage.
Packaging and Storage
Bluwat Polyaluminum Chloride Powder CAS 1327-41-9 is packed in 25 kg bags with inner plastic bag and outer woven bag.
