Natural draft aeration provided by Cascade Aerators

Cascade Aerators are …

• Natural draft gravity aeration for iron oxidation and dissolved oxygen increase
• Capable of adding 5 ppm oxygen and reducing small amount of free carbon dioxide
• Applied to iron removal and wastewater DO boost applications
• Designed for 200 to 5,000 gpm per unit

Features:

• Aluminum Construction
• No moving parts
• Open interior

Benefits:

• Corrosion resistant
• Light weight eases installation
• Economical to operate
• Maintenance free
• Eliminates fouling

Cascade aerators are best applied for oxidation of ferrous iron by addition of oxygen followed by detention and filtration.  Ideal for iron concentrations above 10 ppm as the open structure eliminates fouling from iron precipitation.  They also increase dissolved oxygen at the end of wastewater plants.
