These membranes combine high strength with resistance to contamination and oxidation (PVDF material withstands 250,000 ppm·h of chlorine) as well as acid and alkali resistance (withstands 20% NaOH). They offer a pure water flux of up to 800 L/h, with some membrane products capable of operating at pressures of up to 10 bar and temperatures of up to 90°C. Even when directly filtering domestic wastewater with activated sludge concentrations as high as 40 g/L, the membrane flux remains as high as 70–150 L/h.

Large membrane modules, such as 8-inch and 10-inch units, can significantly reduce capital expenditure and operating costs for large-scale projects. They are commonly used for the treatment of high-concentration industrial effluents—including landfill leachate, pharmaceutical wastewater, alkali recovery, oily wastewater, electronic wastewater and coking wastewater—as well as for the separation of materials such as foodstuffs, fermentation broths and tea beverages.
