PAC Poly Aluminum Chloride: Uses, Benefits & Applications
PAC polyaluminum chloride is a widely used water treatment chemical known for its excellent coagulation and flocculation properties. It is commonly used in drinking water and wastewater treatment, as well as in industrial applications.
Due to its high efficiency, PAC has become a preferred alternative to traditional coagulants like alum.
🔹 What is PAC Poly Aluminum Chloride?
PAC (polyaluminium chloride) is an inorganic polymer coagulant made from aluminum salts. It is used to remove suspended particles, organic matter, and impurities from water.
👉 PAC works faster and more efficiently than many conventional water treatment chemicals.
🔹 Chemical Composition of PAC
Polyaluminium chloride is composed of polymerized aluminum hydroxide complexes.
General representation:
Aln(OH)mCl3n−mAl_n(OH)_mCl_{3n-m}Aln(OH)mCl3n−m
This structure allows PAC to perform effective coagulation in a wide range of water conditions.
🔹 How PAC Works in Water Treatment
PAC polyaluminum chloride works through coagulation and flocculation.
Step-by-step:
- Neutralizes charges of suspended particles
- Forms micro-flocs
- Flocs combine into larger particles.
- Particles settle and can be filtered out.
👉 This process improves water clarity and removes contaminants efficiently.
🔹 Applications of PAC Poly Aluminum Chloride
Drinking Water Treatment
- Removes turbidity and impurities
- Improves water clarity
- Eliminates harmful particles
Wastewater Treatment
- Removes suspended solids
- Reduces organic pollutants
- Improves treatment efficiency
Industrial Applications
- Textile industry
- Paper processing
- Chemical manufacturing
🔹 Benefits of PAC Poly Aluminum Chloride
- High coagulation efficiency
- Works across a wide pH range
- Produces less sludge than alum
- Faster settling time
- Cost-effective for large-scale use
🔹 PAC vs Alum
PAC polyaluminum chloride offers several advantages over aluminum sulfate (alum):
- Better performance in low temperatures
- Lower dosage required
- Reduced sludge production
- Improved water clarity
👉 This makes PAC a more efficient modern coagulant.
🔹 Why PAC is Widely Used
PAC is widely used because it provides:
- Consistent water treatment results
- High adaptability to different water conditions
- Reliable performance in municipal and industrial systems
