based on reverse osmosis,with filter and softener,add mixed bed,EDI to high desalinization ratio,PLC programmable controller
The system is controlled by one single chip (PLC), all movements work automatically under preinstalled procedure and with full automatic function (automatically producing water,automatic flushing,scarcity of Influent water/water tank full of water auto-stop).
* Structure arrangement is compact, has small foot-print, saving space effectively.
* System consumes low energy, thus saves energy effectively.
* Consumables life is long, with low cost of producing water.
* System works safely and reliably, while its water pipeline is closed with stable effluent quality.
Process introduction:
The process is composed of the below parts: The pretreatment,the two-stage reverse osmosis (RO),Electrodeionization(EDI),Ultraviolet sterilization (UV),Polishing mixed bed(MB),Terminal micro filter (MF). The pretreatment part is made of Multi-media filter,Activated charcoal filter and Full automatic softener.
The RO technique is mainly composed of the high-pressure pump,the RO membrane and the control section.
The RO technology technique is one kind of advanced technology features as high efficiency,low consumption in energy,no pollution, is mainly applied in pure water preparation and desalination. The RO technology is one kind of membrane separation filtration technology, using the pressure difference as power, Through the pressure difference, it separates strictly H2O and the impurities like inorganic salt,heavy metal ion,organic matter,colloid,bacterium,virus ,etc in source water.
EDI is a kind of advanced technology integrating electrodialysis and ion exchange technology, The system through optional permeation function of anion,cation exchange membrane to anion and cation, and the exchanging function of ion-exchange resins to ion; can make ion derectional movement under the role of DC electric field, thus finishes water’s deep desalination, It can finish ion-exchange continuous rebirth, needs no halt can use regeneration of resin aicd-base, thereby can products high quality water continuously.
Mixed bed refers to taking negative resin and positive resin into the identical converter according to the certain proportion installment, mix them even before operating. This moment after going through mixed ion-exchange bed, H+ ions and OH- ions processed from water generate into low solubility water immediately. As terminal ultrapure device of process, can make water resistivity exceed over 15 MΩ.cm, to satisfy users’ requirements for high quality water.
