Purified water production process 1. Water production process Tap water → raw water tank → raw water pump → multi-media filter → activated carbon filter → security filter → primary high pressure pump → primary RO device → intermediate water tank → secondary high pressure pump → Secondary RO device → Purified water tank → Purified water pump → Ultraviolet sterilizer → Microfilter → Circulation return at point of use 2. Description of water production process Water tank, raw water pump, multi-media filtration, activated carbon filter to remove mechanical impurities, suspended solids, colloid, organic matter, free chlorine, hardness, etc. in raw water to protect the reverse osmosis membrane from damage and prevent scaling on the surface of the reverse osmosis membrane, Make it meet the influent requirements of reverse osmosis. (2) Part of the reverse osmosis system includes, security filter, primary high pressure pump, primary reverse osmosis membrane module, intermediate water tank, secondary high pressure pump, secondary reverse osmosis membrane module, purified water tank, mainly using reverse osmosis The principle is to pass the pretreated water through the reverse osmosis membrane to divide the water into concentrated water with high salt content and purified water with very low salt content, and remove most of the bacteria and heating sources in the water to meet the requirements of pharmaceutical water. need. (3) Part of the purified water supply system includes purified water pumps, ultraviolet sterilizers, terminal filters, and circulation pipes. The main purpose is to supply purified water to the water points for use, and to make the system form a large cycle to ensure that the water quality of each water point can reach the pharmaceutical level. water requirements.
