This research in the field of water treatment method using the reverse osmosis membrane cleaning formulations by changing technology just extend the lifespan occurs. Currently, almost all of the water used in the field of reverse osmosis membrane technology, the impact of this will be very large. This research will be applied to the present case that the existing device efficiency and lower costs in the economic aspects are judged very good technology. In this study, when membrane fouling by running effective membrane cleaning aims to maximize the effect. To this end, focusing on pressure changes in the initial pressure rise was 10% if the membrane cleaning is carried out. In this case, the amount of acid and alkali can be minimized should find a way. RO membrane in the present invention generally after the initial pressure 10bar pressure compared to just 11.5 ~ 12.0bar initial cleaning when carried out in acid solution below pH 2, pH 12 alkaline solution is carried out in more than 30 minutes each. In this case, the more conduct problems membrane cleaning treatment efficiency of the membrane tends to decrease. Initial production flow decreases and eventually just wash shorter jugido membrane should be replaced. The main reason for replacing the membrane just inside the source is not removed through cleaning. 11bar pressure at the membrane surface when conducting membrane cleaning one of the external contamination by removing the source of contamination inside the membrane prior to the initial state variable is able to keep. In addition, these results in order to reach an appropriate control logic is required.
