The Envirex Diamond edition fine bubble membrane diffuser is custom formulated from an EPDM wastewater specific compound. The tensile strength of this material is 50% greater than any current competitive alternative. Lower soluble oil content in the raw material means an extended life for the membrane, and lower operating costs. A new “Diamond Aperture Configuration” results in much higher oxygen transfer efficiency, as well as a wider operating airflow (up to 5 SCFM).
