Fine Bubble Coarse Type Air Diffuser

coarse bubble diffusers when:

• Strong mixing is required.
• The wastewater contains high solids or grease.
• Maintenance simplicity and resistance to clogging are priorities.

Uses of Coarse Bubble Diffusers

• Wastewater treatment plants
  • Equalization tanks
  • Grit chambers
  • Sludge holding tanks
  • Aerobic digesters
• Industrial effluent treatment
  • Mixing wastewater with high solids, grease, or fibrous materials
• Chemical mixing tanks
  • Keeping chemicals uniformly suspended
• Aquaculture
  • Providing aeration in ponds and tanks where strong water circulation is needed
• Lagoons and oxidation ponds
• Aeration and circulation to reduce odors and improve treatment

• Excellent mixing: Large bubbles create strong turbulence, preventing solids from settling.
• Less prone to clogging: Large openings are more resistant to blockage from sludge, grease, and debris.
• Durable: Suitable for harsh operating conditions and abrasive wastewater.
• Easy maintenance: Requires less frequent cleaning compared with fine bubble diffusers.
• Lower pressure loss: Typically needs lower air pressure to operate, reducing blower pressure requirements.
• Handles variable air flow: Performs well across a wide range of airflow rates.
• Reliable operation: Continues to perform effectively even in challenging wastewater conditions.
