Abstract: PURPOSE: To separate volatile organic compounds from waste stream effectively, a hybrid membrane which is composed of porous membrane layer and non-porous membrane layer is provided. The porous membrane layer has the ability of concentration and has an effect on the characteristic of separation, whereas the non-porous membrane layer has the ability of purification and an affinity for volatile organic compounds. The hybrid membrane can improve the effectiveness of separation by picking out the merits of porous and non-porous membrane layers. CONSTITUTION: The hybrid membrane comprises a porous membrane layer which has the ability of concentration and a non-porous membrane layer which is coated with macromolecules that have an affinity for volatile organic compounds. On one side of the porous layer, a solution containing fillers, including aluminum nitrate, aluminum sulfate, calcium chloride and polyethylene oligomer, is applied, whereas on the other side of the porous layer, negative pressure of 5-300 torr is applied. After forming a porous layer on one side, polydimethyl siloxane oligomer is applied the other side so that a non-porous layer is formed.
