- EDI ultra-pure water for laboratory analysis equipment China National Standard (GB6682-92) "analytical laboratory use specifications and test methods": Index Name: water level, secondary water, three water 1 Water:> 10MΩ ; 2 water:> 1MΩ; 3 water:> 0.2MΩ PH value range (25 ℃): 5.0-7.5 specific resistance MΩ.cm@25℃:> 10 1 0.2 Conductivity (25 ℃) us / cm: ≤ 0.1 15 can oxide [in O count] mg / L: 0.08 0.40 absorbance (254nm, 1cm light path): ≤ 0.001 0.01 silica (mg / L): 0.02 0.05 evaporation residue (mg / L): 1.0 2.0 - EDI ultra-pure water equipment reverse osmosis + EDI principles and process water treatment system (a) - EDI ultra-pure water treatment equipment Guangzhou Tianshui the introduction of the US GE, EXL, Ionpure, Canada Kanpur technology to produce ultrapure water treatment system that uses reverse osmosis + EDI technology, high degree of automation, the system of water, water quality is good (product water resistivity 17MΩ.CM above) and so on. The process is now described as follows: 1. The main task of the multi-media filter stage is a coarse filter tap water, to prepare for entry into the reverse osmosis membrane, prior to entering the reverse osmosis membrane to ensure a certain water quality to protect the reverse osmosis membrane The use of effects and life. The process for the original tank water through sand, activated carbon filter and precision filter, the impurities in the water, organics, colloids, suspended solids removal, Guangzhou Baiyun ultra-pure water equipment offer, to prevent these large particles of impurities into the anti- After the reverse osmosis membrane permeable membrane clogging. After coarse filtration, water quality has improved to some extent. And allow access to the next link. - EDI ultra-pure water equipment 2, a reverse osmosis water filtration through coarse and then through a reverse osmosis membrane is a reverse osmosis, reverse osmosis membrane is semi-permeable membrane, it can prevent Ga2 +, Mg2 +, Fe-2, SO4- 2, Cl-1, Na + and other large ions, Guangzhou Baiyun ultra-pure water equipment supply, in order to ensure the effectiveness and protect the reverse osmosis membrane reverse osmosis, RO vessel must be constantly added to the inhibitor, and must ensure that the temperature at 25 ℃, (winter steam heat exchanger) and guarantee a certain pressure, the Guangzhou Baiyun ultra-pure water equipment manufacturers (using vertical pump) at a certain pressure, the Guangzhou Baiyun ultra-pure water equipment, ion-containing water is squeezed through a reverse osmosis membrane to form two water all through the reverse osmosis membrane water that is finished water into the next part, without going through the reverse osmosis membrane water is discharged through a reverse osmosis treated water then enters the next link - reverse osmosis. - EDI ultra-pure water equipment Guangzhou ultra-pure water equipment, ultra-pure water equipment wholesale Guangzhou, Guangzhou Tianshui (certified merchants) are provided by the Guangzhou Environmental Protection Technology Co., Ltd.
