The 3D scene begins with a slow zoom into the structure of an osmosis membrane, revealing its multilayered design in a detailed cross-sectional view. Each layer is visually distinct—starting with the outer protective layer, followed by the non-woven support layer, the porous substrate, and finally the ultra-thin polyamide active layer responsible for filtration. As impure water flows across the membrane, the animation highlights how each layer performs a specific function: larger particles and sediments are caught in the initial layers, while smaller impurities and dissolved salts are filtered out at the nano-scale by the active layer. The camera smoothly transitions through the layers, showing water molecules passing through selectively while contaminants are blocked or redirected. Clean water exits on the opposite side, glowing softly to signify purity. The scene uses color coding, particle animation, and transparent materials to clearly illustrate the role and function of each membrane layer, creating an educational yet visually engaging experience.
