ETC membrane is used to remove dissolved carbon dioxide in water. Product water carbon dioxide content can be decreased to 0.5ppm. membrane contactor is a kind of special hydrophobic hollow fiber array made of polymer material. Then the array is spiral-wounded onto a water distribution tube, and then the tube is installed into a housing (at the same time, a baffler is formulated inside the housing).                Hollow fiber → Knitted fiber (under microscope) → Knitted fiber (naked eyes) → End surface   Structure of membrane contactor:      Features of membrane contactor: 1) Hollow fibers are knitted into an array, so that a certain space can be kept between these fibers. In this way, thousands of fibers are connected as a whole array which can resist strong water flow and will not break. Besides, the mass transfer efficiency can be improved in the array structure. 2) High fiber density makes it possible of ultimate gas removal from water; 3) Central tube water distribution + Middle baffler structure, change the water flow direction to flush vertically towards hollow fibers, which can improve the mass transfer efficiency between shell side and lumen side.   CO2 removal from water is a necessary process in many industries. Dissolved CO2 in feed water of EDI/CDI and ion exchange column should be removed. Using membrane contactor to remove dissolved CO2 is an easy method without chemical dosing and frequent chemical regeneration, because it is a 100% physical process. At the same time, operation cost is saved and it is more friendly to environment. Traditional CO2 removal technology is “alkali dosing + 2nd RO” process, while using membrane contactor includes only one step: CO2 is taken out by vacuum pump and sweep gas. It has the following advantages compared with “alkali dosing + 2nd RO” process: Process UF+RO+ETC+EDI UF+RO+RO+EDI EDI capacity 300m3/h 300 m3/h Water recovery 70.80% 67.56% Annual water consumption 3661856 m3  3836507 m3 Annual water consumption difference Saving 174651m3 --- Annual power consumption 4.49 million KWH 6.89 million KWH Annual power consumption difference Saving 2.4million KWH --- Equipment investment 2.33 million USD 3.17 million USD Equipment investment difference Saving 0.83 million USD --- Specifications of  ETC membrane contactor: Item Parameters Model ETC-6×28 ETC-10×28 Application CO2 removal from pure water Flux 1~8m3/h 8~25m3/h Fiber material Polypropylene Dimensions Ø6×28 inch Ø10×28 inch Liquid/gas contact area 45m2 120m2 Inner/outer diameter of fiber 0.2/0.3mm Housing material UPVC PH resistance range 1~13 Working temperature 5~60℃ Max inlet water pressure 6.0bar Connect pipe size DN32 / DN20 DN40 / DN20 Contact:Tel:+86 592 6514970Skype:18060902001WhatsApp:18060902001WeChat:18060902001TM: guochukejiQQ:1641011431
