Why PTFE or fEPDM Diffuser Membranes? Read on….

See photos below of fine bubble diffuser membranes with creep (strain) and calcium fouling from hard water. These are from a municipal wastewater treatment plant and are not membranes manufactured by SSI, but our own standard EPDM membranes are likely to have performed similarly under the same conditions. For improved results use our patent-pending fEPDM or PTFE diffusers.
