ETO membrane is used to remove dissolved oxygen in
water. It is operated in three modes according to different deoxygenation
efficiency: vacuum, nitrogen sweep, vacuum + nitrogen sweep. Product water
oxygen content can be decreased to 3ppb.

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).

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.

In many industrial processes, dissolved oxygen in
water has negative influence: corrosion to many materials. It may cause
corrosion to pipes, boiler and other related equipments. Membrane contactor
system is modular designed, easy to operate, no need of chemical. Compared with
vacuum tower and other technology, it has smaller footprint but higher
efficiency!

membrane contactor can be used for deoxygenation in
boiler feed water, semi-conductor and flat plate/TFT process ultra pure water
(to prevent crystal plate bending), food & beverage process water, chemical
industry process water, oil field reinjection water.

According to different deoxygenation
efficiency,  membrane contactor is
usually operated in the following modes: vacuum, nitrogen sweep, vacuum +
nitrogen sweep. Product water oxygen content can be decreased to 3ppb.
