DowThe film components of FILMTEC brand are spiral coil structures, abbreviated as coil structures. It is composed of multiple leaf membrane bags, each leaf of which consists of two film sheets facing each other, a product water channel placed between the two film sheets, and a turbulent grid shaped inlet channel placed on the surface of the film. The three sides of the membrane bag are sealed with adhesive, and the fourth side is opened on a perforated product water collection pipe. Compared with other component structures such as tubular, plate and hollow fiber structures, it has many advantages such as uniform water flow distribution, high pollution resistance, low replacement cost, simple external pipelines, easy cleaning, maintenance and design freedom, and has become the main membrane component structure form at present.
