The Gold Series membrane diffuser from ITT offers high standard oxygen transfer efficiency (SOTE). The combination of a higher SOTE and a better head loss through the membrane results in higher overall standard aeration efficiency (SAE), measured in oxygen delivered per kilowatt hour (kgO2/kWh).
The membrane diffuser is available in three lengths and the Gold series grids can be combined with grids of Silver Series diffusers, giving them flexibility for all basin configurations, including circular or other unusual geometries. The multiple sizes and modular design allow for greater membrane density in tank area coverage which means lower flux and more time for the oxygen to transfer when bubbles are rising.
