The Commercial RO Membrane is a key membrane element that utilizes the principle of selective permeation to achieve substance separation, widely used in water treatment and various industrial fields. Its core value lies in its ability to efficiently retain ions, organic matter, microorganisms, and other impurities in water while allowing water molecules to pass through, thereby achieving liquid purification, concentration, or refinement.
Commercial RO Membranes typically adopt a "composite membrane structure": a porous non-woven fabric serves as the support layer (providing mechanical strength), a polyester layer acts as the intermediate support (enhancing pressure resistance), and an ultra-thin separation layer functions as the surface layer (responsible for separation). This structure ensures the membrane can withstand high pressure without rupturing or deforming while maintaining the integrity of the separation layer.
