Coarse Bubble Diffusers in Jaipur
Coarse bubble diffusers are aeration devices used in wastewater and industrial treatment systems to introduce air into liquids in the form of relatively large bubbles, typically greater than 4–6 mm in diameter. They are designed to provide robust mixing, agitation, and oxygen transfer in applications where preventing solids deposition, scouring tank bottoms, and maintaining circulation is more important than achieving very high oxygen transfer efficiency. They are commonly installed at the bottom of aeration tanks, equalization tanks, and grit chambers, where they ensure continuous suspension of solids and avoid sludge settling. Unlike fine bubble diffusers, they do not clog easily and require less maintenance, making them suitable for handling wastewater with high solids, fats, oil, or grease content.
|
Bubble Size: |
Produces larger bubbles (typically 4–10 mm in diameter). |
|
Oxygen Transfer Efficiency: |
Lower compared to fine bubble diffusers, but sufficient for basic aeration and mixing. |
|
Mixing Capability: |
Provides strong agitation and circulation, preventing solids from settling at the tank bottom. |
|
Clogging Resistance: |
Less prone to clogging due to larger orifices; suitable for wastewater with high solids, oil, and grease. |
|
Durability: |
Constructed from robust materials (such as EPDM rubber, polypropylene, or stainless steel) for long service life. |
|
Airflow Capacity: |
Handles higher air flow rates compared to fine bubble diffusers. |
|
Maintenance: |
Requires less frequent cleaning and maintenance. |
|
Application Areas: |
Commonly used in grit chambers, equalization tanks, anaerobic digesters, and high-strength industrial wastewater treatment. |
|
Energy Use: |
Slightly higher energy consumption due to lower oxygen transfer efficiency, but compensated by superior mixing. |
|
Installation: |
Easy to install and suitable for both fixed and removable piping systems. |
