The Fine Bubble Tube Diffuser features a tubular structure design, providing a large and uniform aeration area.Made primarily of EPDM rubber or silicone, it is acid and alkali resistant, anti-aging, and less prone to clogging. The diaphragm automatically closes when the system stops, effectively preventing sewage backflow. Installation is convenient and flexible, adaptable to different tank sizes. It has a long service life and is suitable for continuous or intermittent aeration. Its applications are wide-ranging, primarily in municipal wastewater treatment plant biological tanks and industrial organic wastewater treatment systems. Tube diffusers wastewater efficiently increases dissolved oxygen in water, promotes microbial degradation, and is suitable for the aeration needs of medium to large-sized water bodies, balancing high efficiency and economy.
