Product Description
The micro bubble pipeline aerator pipe diffuser is a high-efficiency solution for diffused aeration systems, designed to deliver fine and uniform oxygen transfer in municipal and industrial wastewater treatment applications. These bubble diffusers are engineered with premium EPDM, Silicone, or TPU membranes and are compatible with ABS, PVC, or PP support tubes, which can be reused when replacing the membranes. The membranes are perforated with precision micro-holes that automatically open during air supply and close when the air stops, preventing sewage and debris from entering the pipeline and ensuring a non-clogging operation. This unique self-sealing feature provides reliable performance, extended service life, and reduced maintenance costs.
Available in multiple configurations, the fine bubble diffuser design offers optimal oxygen transfer efficiency with low headloss, making it one of the most cost-effective aeration diffusers for wastewater treatment plants, aquaculture, and clean water applications. Depending on your system requirements, these units can be installed singly or in pairs on rectangular and round pipelines using either standard nipple pipe connections or bolted saddle connections, providing versatility and ease of installation.
