Spiral-Wound Membrane Elements

Spiral-wound membrane elements are engineered assemblies consisting of multiple membrane leaves. Each leaf is constructed with a membrane sheet, a permeate spacer mesh positioned between the backsides of two adjacent membrane sheets, and a feed channel spacer placed on the active front surface of the membrane. The three edges of each membrane leaf are sealed using an advanced adhesive, while the fourth open edge connects directly to a perforated central permeate collection tube.

Catering to diverse application requirements, we offer a full portfolio of spiral-wound membrane elements encompassing RO, NF, UF, and MF series, providing a broad selection of molecular weight cut-offs. These products are manufactured leveraging highly stable membrane materials paired with state-of-the-art automated production technologies to ensure consistent quality. They are extensively utilized in filtration and separation processes across key industries including beverage, food, chemical processing, laboratory research, environmental protection, and agro-industrial processing.

The elements feature a compact, space-saving design with an optimized surface-area-to-volume ratio. They are characterized by excellent fouling resistance, superior cleanability, and low maintenance requirements. To accommodate feed fluids with varying viscosities and solid contents, the product line features adjustable feed channel heights enabled by a variety of spacer thicknesses (28 to 120 mils). This customizable design ensures optimal fluid hydrodynamics, reducing energy consumption while maximizing filtration efficiency.
