The graphene-based filtration products are said to be readily scalable to meet the rising commercial demands making them ideal for industrial level, niche applications such as the concentration of beverages, treatment of crude oil/water mixtures, biofuel and industrial wastewater treatments where reverse osmosis (RO) is not suitable due to the fouling tendencies when concentrated liquids are purged through RO cartridges.
Conventional filtering materials (e.g. activated carbon, zeolites, flocculants etc.,) have certain limitations of pH-sensitivity, poor efficiency and recoverability to treat a mixture of wide variety of contaminants present in the wastewater. In contrast, MESOGRAF graphene, being a 2D-material with high surface-area and functional-group tunability, exhibits outstanding adsorption and recyclability capabilities for a wide variety of contaminants.
Dr. Kiran Manga, Grafoid’s Engineering Manager states: “Our MESOGRAF surface engineered graphene derivatives have been successfully deployed to meet the specific requirements (eg. removal of organic dyes from textile and leather industries, phenols and heavy metal ions from ore-processing industry etc.) of our industrial clients. Our GPURE technologies are able to remove up to 99.8% phenol contaminants, 99% dye removal from real-time industrial wastewater samples at neutral pH and room temperature.”
