1. Raw water → raw water pressurizing pump → quartz sand filter → activated carbon filter → water softener (optional) → security filter → first-stage reverse osmosis equipment → aseptic purified water tank → purified water booster pump → ultraviolet sterilizer → microporous filter → EDI system → aseptic purified water tank → ozone sterilizer → purified water booster pump → ozone Sterilizer → ultraviolet sterilizer → microporous filter → purified water water point
2. Raw water → raw water booster pump → quartz sand filter → activated carbon filter → water softener (optional) → security filter → the first stage of reverse osmosis → purified water tank → purified water booster pump → the second stage of reverse osmosis → aseptic purified water tank → ozone sterilizer → purified water booster pump → ozone sterilizer → ultraviolet sterilizer → microporous Filter → purified water water point
3. Raw water → raw water booster pump → quartz sand filter → activated carbon filter → water softener (optional) → security filter → the first stage of reverse osmosis machine → purified water tank → purified water booster pump → the second stage of reverse osmosis → aseptic purified water tank → pure water booster pump → ultraviolet ray sterilizer → microporous filter → EDI system → bacteriological purified water tank → ozone sterilizer → purified water booster pump →Ozone sterilizer → ultraviolet sterilizer → microporous filter → purified water water point (raw water quality conductivity of 1000μS or more is recommended to use this process)
