How long is the replacement period of the reverse osmosis membrane of Dongguan water treatment equipment? Dongguan water treatment equipment reverse osmosis is a reverse migration movement of osmosis. It is a separation method that separates the solute and the solvent in the solution by means of the selective retention effect of the semipermeable membrane under pressure. It has been widely used Purification and concentration of various liquids, the most common application example is in the water treatment process, the use of reverse osmosis technology to remove impurities such as inorganic ions, bacteria, viruses, organic matter and colloids in the raw water to obtain high-quality purity water. So we have to replace it regularly for the quality of purified water. How long is the replacement cycle? In general, the reverse osmosis membrane of water treatment equipment can be replaced once every 1-2 years. The specific situation also needs to be determined according to the quality of the water produced. Within the specified period of use, the water quality of the water treatment equipment does not need to be replaced if it meets the requirements. If the water quality declines, it needs to be replaced immediately. The main reasons are: the service life of the reverse osmosis membrane (replacement time) is uncertain, and it will change due to the quality of the reverse osmosis membrane permeating water. Generally speaking, the quality of the influent water meets the requirements, which is the pretreatment of the pure water equipment If it is stable, the specified service life of the reverse osmosis membrane can be reached. If the water quality of the reverse osmosis membrane reverse osmosis equipment in the previous pretreatment fluctuates greatly, it will seriously affect the performance and service life of the reverse osmosis membrane, and then affect the final water quality. At this time, the reverse osmosis membrane needs to be replaced immediately.
