GAC for Water Treatment | Activated Carbon Filter Media

Intro: Premium activated carbon specifically engineered for water treatment applications. Effectively removes chlorine, organic compounds, and improves taste/odor. Available in GAC, carbon block, and powdered forms for various water treatment needs.

Why Choose Activated Carbon for Water Treatment?

Activated carbon is one of the most effective filtration media for removing contaminants through adsorption - where impurities are trapped within the pore structure of carbon particles.

Key Benefits:

• Chlorine Removal: Protects downstream equipment and membranes
• Organic Compound Removal: Effectively reduces VOCs and pesticides
• Taste & Odor Improvement: Eliminates unpleasant tastes and smells
• Chemical-Free Process: Physical adsorption requires no chemicals

3 Main Types of Water Treatment Activated Carbon

1. Granular Activated Carbon (GAC)

• Particle Size: 0.4-2.5mm
• Applications: Large-scale water treatment systems
• Advantages: High contact time, easy regeneration
• Service Life: 6-24 months

2. Carbon Block Filters

• Filtration Grade: 1-10 micron
• Applications: Point-of-use and final polishing
• Advantages: Combined mechanical and chemical filtration
• Service Life: 3-12 months

3. Powdered Activated Carbon (PAC)

• Particle Size: 10-50 microns
• Applications: Emergency treatment and wastewater
• Advantages: Rapid adsorption, flexible dosing
• Usage: Batch treatment processes
