Patent ID: 10821381

Abstract:
The present invention relates to a drinking water filtration device based on a graphene technologies. The filtration device includes a first filter, a second filter and a faucet. The first filter further includes a first filter element and a first filter element casing. The second filter includes a second filter element and a second filter element casing. A water inlet of the second filter element casing is connected with a water outlet of the first filter element casing. The filtration material of the second filter element is a mixture of graphene oxide-superparamagnetic nanoparticles composites and graphene reinforced diatom ceramic material. A water inlet of the faucet is connected with a water outlet of the second filter element casing. The filtration device of the present invention can fully eliminate various pollutants in drinking water, and has the advantages of simple structure, good filtration effect and high purification efficiency.
