Slide 3: What is activated carbon?
What is activated carbon? A highly porous carbonaceous material with very strong adsorptive capacity • Very high surface area • 1 teaspoon of carbon (5 g) has the same surface area as a football field (≈ 1,000 m²/g) 3
Slide 4: Activated Carbon Feedstocks
Activated Carbon Feedstocks Steam or chemical activation manufacturing processes opens up the porosity RAW MATERIALS • Coal • Peat • Wood • Coconut shells • Olive pits • Peach stones • Various waste by- products Once granular activated carbon (GAC) has been used and is loaded with impurities, it c
Slide 5: Activated Carbon Pore Structure
Activated Carbon Pore Structure GAC Surface Coconut-based A Macro pores r> 25 nm B Meso pores r 1-25 nm C Micro pores r< 1 nm Coal-based • Varies by feedstock • Modified by manufacturing A Macro pores r> 25 nm processes to meet treatment B Meso pores r 1-25 nm objectives for specific applications C
Slide 6: Adsorption Process
Adsorption Process Adsorption proces Driving force Micro pores < 1 nm Meso pores 1-25 nm Macro pores > 25 nm
Slide 7: Activated carbon treatment objectives in water applications
Activated carbon treatment objectives in water applications ACTIVATED CARBON IN WATER TREATMENT OBJECTIVES TREATMENT • Remove hydrophobic compounds, • Taste & odor causing compounds dissolved organics, non- and poorly biodegradable compounds • Organic micro-pollutants (pesticides) • Treats relativel

Slide 11: Copper Sulfate
Copper Sulfate Used to control algae growth and fish parasites in aquariums Topic Description Indication • Protozoa • Algae growth Problem • Highly toxic to freshwater fish • Toxic to invertebrates and live plants • Prolonged exposure may cause anemia, kidney and gill problems Solution • Activated a
Slide 12: Ozone Effects
Ozone Effects Used to improve water quality (colors, odors) by breaking down dissolved organic compounds into simpler forms that can be consumed by bacteria Topic Description Indication • Disinfectant, antibacterial, antiviral, antiprotozoal • Oxidizes organics Problem • Can burn mucus membranes of
