Advantage: 1).Can produce pure water continuously and highly automatic 2).No need chemical to regeneration, easy operation 3).RO system uses imported USA DOW membrane 4).Automatic switch on when low water level, and switch off when high water level 5).RO membrane can wash automatically and reduce pollution 6).Water shortage protection for multi-stage pump 7).Production water conductivity meter can test the monitoring quality on line contionuosly. 8).Low operation Cost and Long life span 9). It is PC program controller 10).Easily control and Maintain 11).Auto membrane flushing 12).Environmental protection, Low power consumption 13) Auto flush/backwash 14) Low /high pressure protection Function: 1. Raw water pump: provide pressure to quartz sand filter/ activated carbon filter 2. Quartz sand filter: get rid of turbidity, suspended mater, organic matter, colloid ect. 3. Activated carbon filter: remove color, free chloride, organic matter, harmful matter and so on. 4.Before the raw water enters the reverse osmosis device, an appropriate amount of scale inhibitor must be added to prevent the precipitation of carbonate, sulfate, etc. 5. Micron filter: prevent any deposition of large Particles, most of the bacteria, and viruses going into RO membrane, the accuracy is 5 um, for holding back any large particulates such as large iron, dust, suspended matter, impurity. 6. High pressure pump: provide high pressure to RO membrane(at least 2.0Mpa) 7. Manually wash RO membrane; 8. Manually wash RO memebrane with chemicals on machine; 8. Machine automatically stops when high water level of purified water, and runs when low level; 9. Multi-stage pumps protect the machine when lack of water;Protection in such cases as no power, lower pressure, higher pressure, shot circuit, creepage, etc
