DN270 and DN128 Disc Diffusers

One PEROTAC catalogue covers two different disc diffusers. DN270 uses an EPDM membrane for fine-bubble aeration, while DN128 is a coarse-bubble disc for aeration and mixing. Their airflow and head-loss characteristics differ, so the two designs should be compared by treatment duty.
