Brief Introduction of reverse osmosis system (What is a reverse osmosis system?)
The reverse osmosis system is mostly use in pure water treatment and mineral water purification.The water purification is the removal of contaminants from untreated water to produce drinking water that is pure enough for its intended use, most commonly human consumption.Substances that are removed during the process of drinking water treatment include suspended solids, bacteria, algae, viruses, fungi, minerals such as iron, manganese and sulphur, and man-made chemical pollutants including fertilisers. (what does reverse osmosis remove?)
1). This system adopts the most advanced Reverse Osmosis pure water filter technic. Its water production conductance rate generally less than 10us/cm, which precedes the national standard GB17323-1998. The water made by this system is asepsis, non-granule and pure.(what is reverse osmosis water?)
2) The RO membranes of this system adopt American hydranautics membrane or the American Dow membrane
Prevention of membrane fouling (including Fe3, Fe2, CaCO3, CaCO4, SrSO4, CaF2, SiO2, iron, aluminum oxide).
Prevention of colloidal material and suspended solid particles from plugging.
To prevent organic fouling
To prevent microbial fouling
To prevent the oxidation of substances on the oxidative damage to membrane
To maintain the ultrafiltration plant capacity stability
RO membranes auto wash and manual wash
RO membranes manual wash with medicine
Pure water high water level auto stop,low water level auto start
Multi-phases pump protected without water
Protected when no power,poor power,large electrical cuttent short circuit,creepage of electricity.

Introduction of reverse osmosis water purification
RO system for producing drinking. The water is first being removed the suspended matter, micelle and other impurity by the quartz sand filter. Then it is being got rid of the organic substance, chlorine, chromo, odor and etc by the active carbon filter and softener filter. The above device composes the consummate pretreatment system. The water which is being pretreated reaches the requirement of the RO system. So as to make the RO equipment run stably during a long period.
The abio-salt, organic substance, bacteria, heat source and other impurity in the water have been removed after the water was being treated through RO system. The ratio of salt-doffed is in the range of 97%-99%.
There are two modes of operation in the system: auto and manual. The system runs automatically by adopting Water Sensor, and Pressure Sensor. The system can produce water automatically in the mode of auto. It is friendly used and safe.
The tow disffuers, are installed in the upper and lower part of the filter. Their main function is to make the compressed air and the water distribute evenly during backwash
1.Adsorption of organic matter in water part of the adsorption rate of 60%:
2.Absorption chlorine, active carbon adsorption removal of chlorine is not a simple role, but its surface as a catalyst, so full of activated carbon adsorption problem does not exist, but the loss of carbon only.
After the quartz sand filter and active carbon filter, the water basically required the water treatment plants water standard: SD1 ≤ 4; TDS≤400
