AquaBlade L Diffuser

Design

Design Advantages

Each Diffuser uses our long term proven silicone rubber membrane technology which has been demonstrated to outperform EPDM and other typical membrane materials in terms of microbial resistance, resistance to temperature.

There are no metal components internal to the diffuser, so chemical cleaning is readily achieved

The Structural pultruded GRP base is very strong, enabling a 5.8m diffuser to require only two supports (4 anchors or bolts), so less time is required for on-site installation, reducing the overall cost of the diffusers

The diffuser air inlet incorporates an integral check valve to prevent backflow

Low profile base plant design maximises the realised aeration volume of any aeration basin

Technical

Performance Characteristics

A high transfer rate of oxygen is produced through the optimised profile of the slits and the slitting pattern. When airflow to the diffuser is stopped, these slits tightly close to prevent backflow of mixed liquor.

• The diffuser membrane will not shrink even after years of operation. The special high quality elastomeric material also provides a high resistance to the formation of biofilms especially when compared to other reputable membrane manufacturers.

• Excellent flow versus back pressure characteristics allowing reduced power consumption.

• Typical airflows range from 3 Nm /h.m to 18Nm /h.m with a maximum of 30 Nm /h.m for both fine and coarse pore membranes (see Diffuser Pressure Loss Curve).

Key Advantages

Key Characteristics

• The concave profile of the Aquabalde L Baseplate allows for air to pass between the baseplate and the silicone membrane serving as an air feed chamber. This pipe like air chamber reduced the need for any additional feed pipes in the bioreactor and also allows the diffusers to be fitted closer to the floor of the reactor increasing tank operational volumes

• By utilising a structural FRP baseplate to retain the proprietary silicone membrane all feed pipework used in conventional diffuser grids is removed from the bioreactor. Only a 2 inch feed is required to feed up to 2 x 5.8m diffusers. Diffuser manifolds can be utilised to offer multiple 2 inch feeds, or multiple 2 inch flexible feeds can be utilised. This versatility offers designers the choice that best suits the application.
