▎ 摘　　要

NOVELTY - The filter module (100) has an outer membrane layer (200) forming an outer surface, an inner membrane layer (400) formed within outer membrane layer, and a graphene filter layer (300) formed between outer and inner membrane layers. The incoming water is filtered through the outer membrane layer, graphene filter layer, and the inner membrane layer. The material selected of filter module is selected from graphene, graphene oxide, reduced graphene oxide, graphene nano particles, and combinations. The material is further selected from activated carbon, carbon black, zeolite, silica, ion exchange resin, alumina, ceramic balls, and carbon nanotubes. The graphene filter layer has 0.1 to 100 parts by weight of graphene, graphene oxide, reduced graphene oxide or graphene nano particles. The outer membrane layer and inner membrane layer has polymeric material selected from cellulose, glass fiber, polyethylene, polypropylene, carbon fiber, activated carbon fiber, and polyethylene terephthalate. USE - Graphene filter module for removing contaminants like industrial wastes and sewage, and heavy metals from raw water of rivers, lakes and streams, and dyeing wastewater and supplying clean water to homes, industries, etc. Can also be used as industrial wastewater treatment filter. ADVANTAGE - The incoming raw water passes through outer membrane layer, graphene filter layer, and inner membrane layer in order and is filtered three times, so as to effectively remove contaminants in the raw water. The fine particles in the dyeing wastewater are removed by the graphene filter layer to obtain clear water. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene filter module.
