Household film

The household membrane element series consists of multi-page membrane bags. Each membrane bag comprises two membrane sheets with their active surfaces facing away from each other, a product water flow channel positioned between the two membrane sheets, and a turbulent-grid-type feed water flow channel placed on the membrane surface. The three sides of each membrane bag are sealed with adhesive, while the fourth side opens into a perforated permeate collection pipe.

◎ Product Introduction and Application Fields

　　The household membrane element series consists of multi-layer membrane bags. Each membrane bag comprises two membrane sheets positioned back-to-back, a product water flow channel sandwiched between the two membrane sheets, and a turbulent-grid-type feed water flow channel placed on the membrane surface. The three sides of each membrane bag are sealed with adhesive, while the fourth side opens into a perforated permeate collection pipe. Flux can be designed according to specific requirements, and multiple models are available for commercial and residential water dispenser manufacturers, distributors, and end-users to choose from based on their varying needs.
