PRODUCT INFORMATION
Overview & application
1. Designed for Efficient Air Distribution and Oxygen Transfer
Disc diffusers release air into water through membrane perforations, generating bubbles that transfer oxygen into the water. Aeration performance depends on membrane design, operating airflow, water depth, air pressure and wastewater characteristics.
A typical disc diffuser consists of a diffuser body, membrane, air inlet connection and associated mounting components. The exact construction and materials depend on the selected model. Proper diffuser placement and air supply design help match the equipment to tank geometry and biological treatment requirements.
2. Engineered for Reliable Aeration Performance
Actual disc diffuser performance depends on product design, material selection, operating conditions and system configuration. ODMS considers aeration requirements, material compatibility, layout and maintenance needs to help identify a suitable configuration.
01｜Fine-Pore Aeration
The perforated membrane distributes air into the water. Actual bubble size and distribution depend on membrane design, airflow and submerged operating conditions.
02｜Flexible Layout Design
Diffuser locations can be planned according to tank dimensions, oxygen demand and air supply conditions to support effective floor layout.
03｜Material Options
Membrane materials are evaluated according to wastewater characteristics, temperature and operating requirements.
04｜System Compatibility
Design airflow, operating pressure, piping resistance and blower operating range are considered together, rather than selecting diffusers based on standalone product data alone.
3. Technical Specifications & Model Selection

4. Installation Designed Around Your Tank and Air Supply System
Disc diffusers must be configured in coordination with tank geometry, floor laterals, air distribution piping and the air supply system. Proper layout helps meet design airflow requirements while allowing for inspection, maintenance and future replacement.
01｜Tank Layout
Plan diffuser locations and spacing according to tank dimensions, effective water depth and process oxygen demand.
02｜Air Distribution
Review design airflow, piping resistance and supply pressure to ensure the air distribution system meets project requirements.
03｜Connections & Supports
Confirm connection specifications, support structures and installation requirements for the selected diffuser model.
04｜Maintenance Access
Allow for inspection space, equipment removal and future maintenance during new-build and retrofit planning.
Project Compatibility
New installations can be configured around the process design. Retrofit projects require additional checks of existing piping, connection interfaces, tank-floor structures and site constraints.
