Polyaluminium Chloride Powder for Water and Wastewater Treatment Chemicals
Product Overview
Polyaluminium Chloride Powder, also known as Polyaluminum Chloride Powder, Poly Aluminium Chloride Powder or PAC powder, is a widely used coagulant chemical for water and wastewater treatment.
It is designed to remove turbidity, suspended solids, colloidal particles, organic impurities and fine particles from water. After dosing, PAC powder helps destabilize small particles that are difficult to settle naturally. These particles then form larger flocs and can be removed by sedimentation, flotation or filtration.
Bluwat PAC powder is produced by spray drying technology and supplied in stable powder form. It offers good solubility, reliable coagulation performance and flexible application across different water qualities.
As one of the commonly used water treatment chemicals, PAC powder can be applied in both clean water purification and wastewater clarification processes.
Why PAC Powder Is Used in Water and Wastewater Treatment
Water and wastewater treatment systems often face different impurity problems.
In drinking water treatment, the main target is to remove turbidity, suspended solids, colloids and fine impurities before filtration and disinfection.
In wastewater treatment, the main target is to reduce suspended solids, turbidity, color, colloids, organic matter and phosphorus load before discharge or reuse.
PAC powder is effective because it supports chemical coagulation. It neutralizes particle charges and helps fine impurities gather into visible flocs. These flocs can then be separated more easily from water.
For many treatment plants, PAC is used as the primary coagulant. When stronger floc formation is required, PAC is commonly used together with PAM flocculant.
Key Advantages
PAC powder helps destabilize suspended solids and colloidal particles, supporting faster coagulation and clearer water.
Under proper mixing conditions, PAC helps form compact flocs that can settle, float or filter more easily.
PAC can be used in drinking water treatment, municipal wastewater treatment, industrial wastewater treatment and many industry-specific effluent systems.
Bluwat supplies PAC-01, PAC-02 and PAC-031 grades to meet different water treatment requirements.
The spray dried powder dissolves well in water and can be prepared as a dosing solution for continuous treatment operation.
PAC is often used before PAM flocculant to improve coagulation, floc size and sedimentation performance.
PAC powder is packed in 25 kg bags, suitable for warehouse storage, container loading and export supply.
Bluwat provides stable PAC powder quality, technical support and export service for global water treatment customers.

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 colloids before filtration.
PAC powder can support sewage treatment plants by improving coagulation, suspended solids removal, phosphorus removal support and effluent clarity.
PAC powder is widely used in industrial wastewater treatment systems to reduce turbidity, TSS, color, organic impurities and colloidal particles.
For textile and dyeing wastewater, PAC can help improve coagulation and floc formation. It is often used together with water decoloring agent and PAM flocculant.
PAC helps remove fibers, fillers and suspended solids from paper mill wastewater and supports better sludge separation.
PAC powder improves solid liquid separation in mining wastewater and coal washing wastewater, helping reduce fine suspended particles.
PAC can be used for food processing wastewater pretreatment to reduce suspended solids and improve clarification before further treatment.
PAC powder is suitable for wastewater with unstable colloids, fine particles and mixed industrial impurities.
How PAC Works in Treatment Process
PAC powder is normally dissolved in clean water before dosing.
After the PAC solution is added into water or wastewater, it disperses under rapid mixing and contacts suspended particles and colloids.
PAC neutralizes the surface charge of these particles. As the particles lose stability, they start to combine and form micro flocs.
During slow mixing, these micro flocs grow into larger flocs. If PAM flocculant is added after PAC, the flocs can become stronger and settle faster.
Finally, the flocs are removed through sedimentation, dissolved air flotation or filtration.
This process helps improve water clarity and supports stable operation of downstream treatment units.
Suggested Dosing Sequence
For most water and wastewater treatment applications, the suggested process is:
First, prepare PAC powder solution with clean water.
Second, dose PAC solution into water or wastewater under rapid mixing.
Third, allow PAC to fully contact suspended solids and colloids.
Fourth, adjust pH if needed according to jar test results.
Fifth, add PAM flocculant under slow mixing when larger flocs are required.
Finally, separate the flocs by sedimentation, flotation or filtration.
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.
PAC and PAM Combination
PAC and PAM are both important water treatment chemicals, but they have different functions.
PAC is a coagulant. It neutralizes the charge of fine particles and starts the coagulation process.
PAM is a flocculant. It bridges small flocs into larger flocs and improves sedimentation speed.
In many wastewater treatment systems, the common dosing order is PAC first and PAM second. This combination is widely used in municipal wastewater, industrial wastewater, textile wastewater, paper mill wastewater and mining wastewater treatment.
