products in domestic and commercial water treatment equipment. Although the reverse osmosis membrane itself has certain anti-pollution properties, if the RO membrane is not effective for a long time during the whole production operation, Protection, coupled with long-term accumulation of pollutants in the water, membrane fouling will occur.
At this time, the transmittance of the film is reduced, the membrane flux is lowered, the life of the membrane is greatly reduced, and the production running cost is continuously increased. Therefore, in the whole process of the reverse osmosis membrane, the analysis is carried out according to factors such as the process of the membrane, the amount of permeation, the performance of the membrane, and the correct method is maintained and improved.
It is necessary to carry out regular cleaning and maintenance, but pay attention to the influence of operating pressure on membrane fouling during the cleaning process. In the primary stage of membrane operation, due to the large adsorption between membrane and solute, increasing the operating pressure at this time can make Many solute molecules penetrate into the past, which in turn reduces membrane fouling.
However, an increase in operating pressure causes an increase in the deposition rate of colloidal substances on the surface of the membrane, which further accelerates the rate of membrane fouling. Therefore, in the actual operation process, the determination of the operating pressure should be reasonably selected according to the actual situation, and in order to better control the membrane flux, the corresponding warning value should be set, and when the transmembrane pressure difference reaches a certain value, the membrane cleaning is performed.
