Coarse Bubble Diffuser – ProFlex™ Style 730CBD
The Proco ProFlex™ Style 730CBD is a state-of-the-art coarse bubble diffuser designed for the most demanding wastewater treatment applications. It is an engineered, molded, non-clogging, elastomeric duckbill-type mixing valve. As an essential component in aeration systems, it is responsible for introducing oxygen into wastewater, promoting the breakdown of organic matter, and creating a powerful mixing action that is strong enough to carry sewage effluent to the surface for removal. Its robust construction and unique design ensure reliable, long-lasting performance with minimal maintenance.
How Does It Work?
The ProFlex™ 730CBD operates with a simple yet highly effective mechanism driven by an air blower or compressor:
Air Injection – Pressurized air is delivered to the diffuser, which is installed at the bottom of the treatment tank.
Bubble Formation – The air flows through the diffuser’s specially engineered orifices, creating a continuous stream of coarse bubbles.
Wastewater Aeration & Mixing – These bubbles rise through the wastewater, efficiently transferring oxygen. This action promotes complete mixing of the reservoir, lifting sludge and sediment to the surface for removal.
Backflow Prevention – When the air supply is turned off, the diffuser’s unique elastomeric duckbill design closes bubble-tight around a 360˚ periphery. This innovative feature prevents any backflow of wastewater into the aeration system, protecting your equipment and minimizing maintenance.
What are the Main Applications?
The ProFlex™ 730CBD is ideal for a wide range of industrial and municipal wastewater treatment applications where low maintenance and long life are required, including:
- Grit Chambers
- Equalization Basins
- Sludge Holding Tanks
- Aerobic Digesters
- Post-Aeration Systems
Key Features and Benefits
The ProFlex™ 730CBD coarse bubble diffuser offers a host of features and benefits:
- High-Efficiency Mixing: The coarse bubble design provides excellent mixing and aeration, leading to improved treatment efficiency.
- Low Maintenance: The self-cleaning, non-clogging elastomeric duckbill design prevents backflow and clogging, significantly reducing maintenance requirements.
- Durable Construction: Made from high-quality elastomers, the diffuser is built to withstand harsh operating conditions and provide a long service life.
- Easy Installation: The standard 3/4” NPT stainless steel hex nipple allows for quick and secure installation with a positive seal.
The design of the ProFlex™ coarse bubble diffuser prevents backflow of media and fluids into the diffuser and manifold piping. Exiting airflow discharges towards the floor of the chamber eliminating accumulation of solids. This in turn creates a complete overturn loop which ensures high mixing of the reservoir, once again resulting in minimal maintenance.
The ProFlex™ 730CBD design provides the engineers with SCFM information for each orifice size which allows the Engineer / Municipality to design and implement their air pump / compressor flow data which in turn lowers design costs.
