ProFlex™ Series 730CBD Coarse Bubble Diffusers

Coarse bubble diffusers are a sought after pollution control technology used to aerate or mix wastewater for effluent/sewage treatment. Coarse bubble diffusers produce 1/4 to 1/2 inch (6.4 to 13 mm) bubbles which rise rapidly from the floor of a wastewater treatment plant or sewage treatment plant tank. They are typically used in grit chambers, equalization basins, primary and secondary settling ponds, and many other areas where sediment settling is a concern.

Benefits of The ProFlex™ 730CBD

When a diffuser system is operational the complete system is charged by an air blower or a compressor , this ensures the volume of air is always exiting the valves outlet, but what happens when the air is suddenly missing, or a power failure occurs?
PROCO 730CBD Series Coarse Bubble Diffuser In other aeration systems including fine bubble elastomeric design, the media can encounter a sudden backflow into the aeration manifold as well as the blower or air compressors internals. The ProFlex™ 730CBD with its unique elastomeric duck bill design is always in a 100% closed position and relies on static head to open, so the instant there is an absence of inlet pressure the valve is closed bubble tight ensuring unwanted media does not flow back into the manifold.
With the ProFlex™ 730CBD being an all-elastomeric design, there is no concern for maintenance or costly down-time resulting in a perfect diffuser system, designed to provide long life features. The ProFlex™ 730CBD also features a “Hex” 3/4″ NPT SS nipple instead of a standard SS pipe nipple, this feature allows the owner/contractor a hassle-free install experience, ensuring a positive seal on the manifold without worry of breaking the adapter or the manifold’s inlet fitting.
EPDM or Neoprene is the most specified elastomer, and both offer superb flexibility along with long life designed elastomers. (Other elastomers are available)

When to use a ProFlex™ 730CBD

To prevent backflow of media and fluids into the diffuser and manifold piping. Exiting airflow is designed to discharge 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.
Another benefit is the economics of the ProFlex™ 730CBD design, with its simplistic yet engineered models the Customer can see huge savings over a more costly maintenance ridden design. The ProFlex™ 730CBD design provides the engineers with SCFM information for each orifice size which also allows the Engineer/Municipality to design and implement their air pump/compressor flow data and engineer their own system which greatly lowers design costs, (see dia vs SCFM below)
