Tube Settler Media provides a large settling surface area within the specified volume thus giving high flow rates. They have a chevron shaped self-supporting structure in a tubular form with six sides. They are primarily used in applications like water treatment, primary secondary clarifiers in wastewater treatment.

MBBR (Moving Bed Biofilm Reactor) media specifications typically include size, shape, density, specific surface area, and void ratio. Common sizes range from 10mm to 25mm in diameter and 7mm to 25mm in length. The density is usually between 0.93 and 0.98 g/cm³, and the specific surface area can range from 350 to 1200 m²/m³. The void ratio, or the amount of empty space within the media, is typically between 60% and 90%

Parameter Typical Value / Range Notes

Type Granular Activated Carbon (Coconut Shell based preferred) High hardness, low attrition
Particle Size 6 × 12 mesh (1.70 – 3.35 mm) or 8 × 16 mesh (1.18 – 2.36 mm) Common for CIP/CIL
Iodine Number 900 – 1100 mg/g minimum Measures overall adsorption capacity
Gold Adsorption (K-Value) ≥ 30 g Au/ton carbon Direct measure of gold adsorption capacity
R-Value (Elution) ≥ 0.8 Indicates ease of gold elution/desorption
Apparent Density 480 – 520 kg/m³ Bulk density of carbon
Hardness / Attrition Resistance ≥ 98% (ASTM D3802) Minimizes fines generation during agitation
Moisture Content ≤ 5% As packed
Ash Content ≤ 4% Lower ash improves performance
pH (10% slurry) 9 – 11 Mildly alkaline
Surface Area (BET) 900 – 1100 m²/g Porosity measure
