Spray Dried Polyaluminum Chloride Powder for Water Purification
Product Overview
Spray Dried Polyaluminum Chloride Powder, also called PAC powder or Poly Aluminium Chloride powder, is a commonly used water purification chemical for coagulation and flocculation.
It is produced by spray drying technology, which converts liquid PAC into stable powder form. The powder product is easy to pack, store, transport and dissolve before dosing. Compared with liquid products, spray dried PAC powder is more convenient for long distance shipment and warehouse storage.
In water purification systems, PAC powder helps remove turbidity, suspended solids, colloidal particles and organic impurities. It can improve water clarity and support sedimentation, filtration and downstream treatment processes.
Bluwat supplies spray dried PAC powder in different grades, including PAC-01, PAC-02 and PAC-031, to meet different water treatment requirements.
What Is Spray Dried PAC Powder
Spray dried PAC powder is made from liquid Polyaluminum Chloride through a spray drying process. During this process, the liquid material is atomized and dried into fine powder under controlled conditions.
This production method helps produce PAC powder with stable appearance, good solubility and consistent active content. The powder form is suitable for international export, bulk storage and flexible use in water treatment plants.
Spray dried PAC powder can be dissolved in water to prepare a dosing solution. After dosing into raw water or wastewater, it works as a coagulant to destabilize particles and promote floc formation.
Why Spray Dried PAC Is Used for Water Purification
Water purification requires stable chemical performance and efficient impurity removal. Raw water and wastewater may contain fine particles, clay, colloids, organic matter, color bodies and suspended solids.
Spray dried PAC powder provides strong coagulation ability. It helps fine impurities gather into larger flocs, making them easier to settle or remove by filtration.
Because of its powder form, it is easy to transport and store. This is especially useful for water treatment plants, industrial users, distributors and export customers who need stable supply and long shelf life.
Key Advantages

Cost Effective Treatment
With suitable dosage and proper application, PAC powder can help improve treatment efficiency and reduce overall operating cost.
Product Grades and Specifications
Bluwat provides multiple grades of spray dried PAC powder.
PAC-01
PAC-02
PAC-031
Different water treatment systems may require different PAC grades. The final selection should be based on water quality, treatment target and jar test result.
Main Applications
Drinking Water Purification
Spray dried PAC powder can be used for raw water clarification in drinking water treatment plants. It helps remove turbidity and suspended particles before filtration and disinfection.
Municipal Wastewater Treatment
PAC powder supports coagulation and sedimentation in municipal wastewater treatment systems. It can help reduce turbidity, suspended solids and phosphorus load.
Industrial Wastewater Clarification
For industrial wastewater containing fine particles and colloids, PAC powder helps improve clarification and solid liquid separation.
Textile Wastewater Treatment
PAC can be used in textile wastewater treatment to support turbidity removal and floc formation. It is often used together with water decoloring agent and PAM flocculant.
Paper Mill Wastewater Treatment
PAC powder helps remove fibers, fillers and suspended solids from paper mill wastewater and supports sludge separation.
Mining and Coal Washing Wastewater
In mining and coal washing wastewater, PAC powder promotes aggregation of fine mineral particles and improves water clarification.
Food Processing Wastewater
PAC can be used for wastewater from food processing plants to reduce suspended solids and improve pretreatment efficiency.
How to Use PAC Powder
Spray dried PAC powder should usually be dissolved in water before dosing.
A typical use process includes the following steps.
-
1
First, prepare a PAC solution with clean water.
-
2
Second, dose the solution into raw water or wastewater under rapid mixing.
-
3
Third, allow PAC to fully disperse and contact suspended particles.
-
4
Fourth, continue slow mixing to support floc growth.
-
5
Fifth, add PAM flocculant if larger flocs and faster sedimentation are required.
-
6
Finally, separate the flocs through sedimentation, flotation or filtration.
Jar testing is recommended before full scale application. The correct dosage depends on turbidity, pH value, water temperature, suspended solids, organic matter and treatment target.
PAC Powder and Water Purification Performance
PAC powder is mainly used in the coagulation stage of water purification. It does not simply filter impurities by itself. Instead, it changes the stability of fine particles in water and helps them form removable flocs.
This makes PAC powder an important chemical before sedimentation and filtration. When the coagulation step works well, the whole water purification process can become more stable and efficient.
In many treatment systems, PAC is used together with PAM. PAC forms micro flocs, and PAM enlarges the flocs for better settling performance.
Packaging and Storage
Bluwat spray dried PAC powder is packed in 25 kg bags with inner plastic bag and outer woven bag.
