Disc tube high-pressure membrane nanofiltration membrane series
FFM’s DTNF disc-tube high-pressure nanofiltration membrane delivers high water recovery rates, stable water quality, and superior fouling resistance for landfill leachate, high-salinity streams, and complex industrial wastewaters (chemical, metallurgical, electroplating). It enables fully automated, pretreatment-free operation, cutting operating costs by 30%, reducing footprint by 40%, and extending service intervals to 6–12 months for efficient&reliable treatment.
