Powder Activated Carbon for Fish Pond

Particle Size:

• Fine powder with particle size typically ranging from 10 to 100 microns.
• Smaller particles provide a higher surface area for adsorption.

Iodine Number (Indicator of Adsorption Capacity):

• Minimum 600–1200 mg/g.
• Higher iodine numbers indicate better adsorption efficiency.

Moisture Content:

• Should be less than 8–10%.

pH Range:

• Neutral to slightly alkaline, typically 6–9, to avoid altering pond water pH significantly.

Ash Content:

• Low ash content, generally less than 10–15%, to minimize residue.

Surface Area:

• Usually around 600–1200 m²/g, which allows efficient removal of impurities.

Apparent Density:

• 0.3–0.6 g/cm³, depending on the source material and activation method.

Source Material:

• Derived from coconut shells, wood, or coal, as these provide different adsorption properties. For fish ponds, coconut shell-based PAC is often preferred due to its high purity and lower impurities.

Water Solubility:

• Insoluble in water to prevent disintegration or contamination.
