Column-type Inner Pressure Membrane Series
FFM’s inside-out hollow fiber ultrafiltration membrane modules feature an innovative internal flow design where feed water permeates from the fiber lumen to the shell side, significantly enhancing fouling resistance and ensuring long-term flux stability.
Made from high-strength PES/PS materials with excellent chemical resistance (pH 1.5-13), these modules deliver reliable filtration performance across diverse applications including electronic-grade ultrapure water production, pharmaceutical purified water systems, municipal drinking water treatment, industrial water reuse facilities, and reverse osmosis pretreatment systems.
