This is the RO system for producing drinking . The producing capacity is 4000L/H. The water supply is tap water. 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, chroma, and etc by the filter. The above device compose 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 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.

3. The ro system working principle.3.1 Machine filter( The quartz sand filter.)

The raw water is purified simple by the filter. The filter mainly get rid of the suspend matter, colloid and other big impurity. If pressure dispersion of the water entering and water out exceeds 10Psi(0.7kg/cm2)or the water out SDI>5, the filter need to be backflushed. Commonly, the filter should be backflushed once before operation every day.

3.2 The active carbon filter.

The active carbon is made of the wood, coal, fruit shell (stone) and other carbonaceous material through the method of chemical activation or physical activation. It has a great deal of micro-holes and huge surface, so it has very strong physical adsorption capability to adsorb the organic infecting in the water. The filter mainly remove the organic substance, chlorine, odor, chroma and etc to make the left chlorine ≤0.1mg/l.So as protect the RO membrane from damage by the chlorine. The active carbon should be replaced every 12 to 18 months according to the content of the chlorine mostly. Commonly, the filter should be backflushed every week.

3.3  The RO device.

The RO device removes the hydronium, organic substance, colloid, bacteria and other impurity by the method of membrane. And the water can be desalted and purified. The theory is as follows. The treated water and the untreated water are separated by the membrane; the treated water osmoses to the untreated water. There is osmotic pressure between the two. If the pressure is added to the untreated water and the pressure of the untreated water is bigger than the osmotic

pressure, the water of the untreated water osmoses to the opposite position of the water. This applies the reverse osmosis to the desalted water. That is to say the untreated water is purified into the pure water through the RO membrane under adequate pressure. The left water which can not osmosis through the membrane contains a lot of solute and suspended substance, and it will be drained out as waste water.

The RO device consists of 5µm precision filter, high-pressure pump, the pure water tank, the pressure vessel, electricity controlled panel, the pressure gauge, the flow meter, the conductivity meter and etc.

The water must be pretreated before entering into the RO system, or it will bring damage to the RO membrane.

The production of water is monitored by the liquid crystal display conductivity meter.

Commonly, the RO system should work once every day. If it does not work in one week, it must be protected by some measure, or the service life of the membrane will be serious affected.
