Overview
EPDM/ Silicone microporous membrane air tube diffuser is developed for enhancing the efficiency and operating models of the activated sludge processes for wastewater biological treatment. The design of the membrane sleeve prohibits clogging of the aeration pores which are self-closing when air flow/pressure is interrupted. Installed with clamp saddle, most existing diffused air systems can be easily retrofitted.
Features
- Low pressure loss.
- Strong sealing, no air leakage.
- High oxygen transfer efficiency.
- Simple structure, easy to install.
- Corrosion resistant, anti-clogging.
- Maintenance-free design, long service life.
