5

• Filters ions (like ammonia)

• Filters raw organic materials

• Industrial landfills

• Re-activation

• Cement production

Why GAC?

Helix Data

• gap widths between the tips of rakers: 0 - 750 µm

• velocities at which flow approached the rakers: 35 - 70 cm/s

• ratio of slot width to rib height ~ 3–4

Calculation of Sediment Volume in physicalfilter• Annual rain at Valley State University: 775mm

• Annual drained water: 100mm

• Surface area per filter pipe: 100m2

• Concentration of sediment: 500g/m3

→ ~ 13,6 g/day

• Density of filtrate: ~ 960kg/m3

→ ~ 1,4 cm3/day
