Xi'an laboratory ultra-pure water equipment

A detailed description of Xi'an high-water laboratory equipment ???? a laboratory high-water equipment, simply put, is the laboratory used for making the experiment of high-water equipment. Due to the different requirements of different experiments on water quality, high-water equipment should also have a variety of different specifications of the water output. Second, the preparation of a pretreatment system reverse osmosis system → → → crude intermediate tank mixed bed → fine mixed bed → pure water tank → → pure water pump ultraviolet disinfection mixed bed polishing → → → precision filter water objects (≥18MΩ. CM) (traditional crafts) 2, reverse osmosis pretreatment → → intermediate tank → pump → EDI system → purification tank → pure water pump → UV disinfection → polishing mixed bed → 0.2 or 0.5μm Ultrafilter → Water target (≥18MΩ. CM) (the latest technology) 3, reverse osmosis pretreatment → → Dosing machine (PH adjustment) → intermediate tank → second stage reverse osmosis (positively charged reverse osmosis membrane) → pure water tank → pure water pump → EDI system → ultraviolet disinfection → 0.2 or 0.5μm Ultrafilter → Water target (≥17MΩ.CM) (the latest technology) 4, reverse osmosis pretreatment → → intermediate tank → pump → EDI system → pure water tank → → pure water pump ultraviolet disinfection → 0.2 or 0.5μm Ultrafilter → Water target (≥15MΩ.CM) (the latest technology) 5, pretreatment system reverse osmosis system → middle → → pure water tank pump → → refined crude mixed-bed mixed bed → → Precise UV disinfection Filter → Water target (≥15MΩ.CM) (traditional crafts) Third, equipment principle ??????? laboratory ultrapure water machine usually raw water pretreatment system, reverse osmosis purification system, after-treatment system consists of three ultra-purification part. Pretreatment main purpose is to make raw water to water requirements reverse osmosis membrane module, ensure the stable operation of reverse osmosis purification system. RO system is a one-time removal of more than 98% of the raw water ions, organic matter and microorganisms to 100% (theoretically) the most cost-effective method for purification. Ultra-purification post-processing system through a variety of integration technologies to further remove the remaining traces of reverse osmosis water ions, organic matter and other impurities in order to meet the final requirements of water quality indicators for different purposes.
