US 2026/0296944 A1 · FLUID PURIFICATION DEVICE USING NANO FILTRATION

Abstract

A fluid purification device is provided. The fluid purification device includes a first filter, a second filter, a bypass valve in fluid communication between the first filter and the second filter, a fluid blender in fluid communication with the bypass valve and the second filter, and a third filter. The first filter includes a prefilter in fluid communication with a fluid inlet for the fluid purification device to receive fluid from the fluid inlet and output prefiltered fluid. The second filter includes a nanofilter in fluid communication with the first filter to receive the prefiltered fluid and output nanofiltered fluid. The bypass valve variably controls flow of the prefiltered fluid therethrough. The fluid blender receives the prefiltered fluid from the first filter via the bypass valve and the nanofiltered fluid from the second filter and outputs a blended fluid. The third filter includes a filtration medium in fluid communication with the fluid blender to receive the blended fluid and output pure fluid.
