The technical staff in field can be extended as needed, as used two or more in parallel in first order reverse osmosis membrane apparatus
Reverse osmosis membrane assembly.
The first order reverse osmosis unit 10 that the utility model is made up of two counter-infiltration membrane modules in parallel is system event
Barrier processing provides a buffer time, and in handling failure, system can also be run, and thereby ensure that the stability of system.Pass through
Increase automatically controls first 18 and realizes itself clean on more medium filter 3, active carbon filter 4 and softening filter 5, prolongs
The service life of pretreatment system is grown.By setting the first return line 16 after the second reverse osmosis unit, after EDI modules 14
If the second return line 17, remaining water backflow raising water resource utilizes after the second reverse osmosis unit and EDI modules 14 are handled
Rate.
In one embodiment of the present utility model, the production procedure of the ultra-pure water process units is specially：Raw water is led to
After raw water pump is crossed by milipore filter progress first time filtering, the first filter mechanism, the second filter mechanism and the 3rd mistake are continuously entered
Filter structure, first filter mechanism, the second filter mechanism and the 3rd filter mechanism are controlled by Full-automatic flushing valve, energy
Enough to realize backwash, the purpose of backwash is to wash away the filter residue remained in filter mechanism, the filtering in filter mechanism is situated between
Matter regenerates.There is the salting liquid containing potassium, sodium ion in other salt box, for being lived again to the medium of the 3rd filter mechanism.
Cartridge filter is entered by pretreated raw water, after cartridge filter removes the particle that turbidity is more than 1, passes through high pressure
Pump enters reverse osmosis unit and carries out osmosis filtration, and after detection electrical conductivity is no more than preset value, water is divided into EDI modules
From pole water, concentrated water and fresh water being separated, pole water and concentrated water enter wastewater treatment equipment by the second return line, and fresh water passes through
It is up to standard after Resistivity testing, obtain ultra-pure water.
It the above is only preferred embodiment of the present utility model, it is noted that above-mentioned preferred embodiment should not regard
For that should be defined to limitation of the present utility model, the scope of protection of the utility model by claim limited range.For
For those skilled in the art, do not departing from spirit and scope of the present utility model, can also make some
