- High Oxygen Transfer Efficiency: Micro-bubbles of 1-3 mm create a large interfacial area, achieving oxygen transfer efficiency up to 30% and reducing blower energy demand.
- Durable EPDM Membrane: Premium EPDM rubber resists fouling, ageing and chemical attack, delivering a long service life with minimal maintenance.
- Non-Clogging Check-Valve Design: Each diffuser incorporates a built-in check valve and slotted membrane that prevent backflow, sludge ingress and clogging during shutdown.
- Uniform, Adjustable Aeration: The perforated support tube provides even airflow distribution across the tank, adjustable through the blower and valve network.
- Simple, Modular Installation: Diffusers mount on standard pipe grids with a simple saddle connection, allowing aeration tanks to be built or expanded in line with demand.
- Corrosion-Resistant Construction: Support tube and fittings are manufactured from durable, corrosion-resistant materials suitable for municipal and industrial sludge.

Diffusers are individually pressure-tested and packed in protective cartons, with mounting saddles and a detailed installation guide included. The system can be delivered as a complete grid package with pipework and valves, or as individual diffusers to suit existing infrastructure. We provide commissioning advice and a responsive spare-membrane service to keep oxygen transfer at design performance throughout the aeration system's life.
