Problems solved by technology

However, traditional water treatment processes cannot effectively remove these trace pollutants, and the ozone oxidation process equipped as a high-purity water facility is still limited in treating 1,4-dioxane to an appropriate level
Also, the increase in water demand is shortening the cycle of used water by reprocessing the water after it is drained
Ultimately, although these factors are progressive, they invariably lead to an increase in the water from various sources of pollution and a consequent shortage of available water resources
[0005]In fact, frequent water pollution a

Embodiment

[0051] Hereinafter, the present invention will be described in more detail with reference to examples. These embodiments are only used to illustrate the present invention more specifically, and it should be clear to those skilled in the art that the scope of the present invention is not limited to these embodiments according to the gist of the present invention.

[0052] Manufacture of composite oxide separation membrane

[0053] figure 2 A method for manufacturing an electrocatalytic separation membrane according to an embodiment of the present invention is shown. refer to figure 2 , electrocatalytic filters were prepared using the drop casting technique (step 1) as well as the electrospinning coating technique (step 2). The exposed Ti filter (width 7.5 cm, length 6.5 cm, thickness 0.5 mm) was washed with lotion solution and ultrasonicated for 15 min in alkaline solution (5% NaOH) and acid solution (10% oxalic acid) at 90 °C for 1 hour, washed with distilled water and...

Abstract

Disclosed is an electroconductive separation membrane for water treatment, the membrane comprising: a metal filter support in a fibrous form; a metal oxide coat layer deposited on the support; and a composite metal oxide catalytic layer applied onto the nanoparticles. Provided is a water treatment system in which the degradation of non-biodegradable organics by electrochemical reactions and the separation of particulate substance through a separation membrane can be simultaneously conducted by water treatment with the electrocatalytic separation membrane according to the present invention. Inaddition, such a water treatment system can exhibit an excellent treatment yield when applied to the advanced treatment of industrial wastewater and can prevent membrane fouling during batch-type andcontinuous type operation by controlling the sheet-type electroconductive separation membrane.

Description

technical field [0001] The present invention relates to a conductive separation membrane for water treatment coated with a composite oxide and a manufacturing method thereof. More specifically, it relates to adjusting the pore size of a filter by impregnating metal oxide nanoparticles on a fibrous metal filter support, and A composite oxide-coated conductive separation membrane for water treatment capable of simultaneously performing electrochemical reactivity and filtration by sintering a coated composite metal oxide catalyst and a manufacturing method thereof. Background technique [0002] Trace amounts of harmful substances in industrial wastewater or sewage treatment water that cannot be removed by existing biological methods may cause widespread and serious problems as new sources of pollution in water systems and drinking water sources. In fact, regardless of domestic and foreign countries, whether in developed or developing countries, the pollution of drinking water s...
