PAC Chemical Powder for Coagulation and Flocculation Water Treatment
Product Overview
PAC Chemical Powder, also known as Polyaluminum Chloride powder or Poly Aluminium Chloride powder, is an inorganic polymer coagulant widely used in water treatment.
In many water and wastewater treatment systems, coagulation and flocculation are important steps for removing turbidity, suspended solids, colloids and other fine impurities. These particles are often too small to settle naturally and may remain stable in water.
PAC powder helps start the coagulation process by neutralizing the surface charge of suspended particles and colloids. After the particles become unstable, they begin to gather into small flocs. With proper mixing and the addition of flocculant when needed, these flocs become larger and easier to separate.
Bluwat PAC powder is produced by spray drying technology and supplied in stable powder form. It is widely used in drinking water purification, sewage treatment, industrial wastewater clarification, paper mill wastewater, textile wastewater, mining wastewater and food processing wastewater.
Coagulation and Flocculation in Water Treatment
Coagulation and flocculation are closely related, but they are not the same process.
Coagulation is the first step. It uses a coagulant such as PAC to neutralize the charge of fine particles and colloids in water. This allows the particles to lose stability and begin to combine.
Flocculation is the next step. During slow mixing, the small particles and micro flocs grow into larger flocs. If PAM flocculant is added, the flocs can become bigger, stronger and faster settling.
In many treatment systems, PAC and PAM are used together. PAC works as the coagulant, and PAM works as the flocculant.
How PAC Powder Works
After PAC powder is dissolved in water and dosed into the treatment system, it disperses quickly under rapid mixing.
PAC interacts with suspended solids, colloids and organic impurities. It neutralizes the particle charge and helps form micro flocs.
During the flocculation stage, these micro flocs grow into larger flocs. The flocs can then be separated by sedimentation, dissolved air flotation or filtration.
This process helps reduce turbidity, suspended solids and fine particles, improving water clarity and supporting downstream treatment performance.
Key Advantages
Recommended PAC Grades
The suitable grade should be selected according to water quality, turbidity, pH, suspended solids, treatment target and budget.
Typical Applications
PAC and PAM Dosing Sequence
For many wastewater treatment applications, the recommended sequence is PAC first and PAM second.
This sequence helps achieve better coagulation and flocculation performance. If PAM is added before PAC, the treatment effect may be weaker because the particles have not been fully destabilized.
Suggested Use Method
A typical use process includes the following steps.
Jar testing is recommended before full scale application. The best dosage depends on water quality, pH, turbidity, suspended solids, alkalinity and treatment goals.
Packaging and Storage
Bluwat PAC powder is supplied in 25 kg bags with inner plastic bag and outer woven bag.
Storage recommendations:
- Store in a cool, dry and well ventilated warehouse.
- Keep away from moisture and direct sunlight.
- Keep the bags sealed before use.
- Avoid contact with incompatible materials.
- Use the product promptly after opening.
Good storage helps maintain powder quality, solubility and coagulation performance.
