Problems solved by technology

These pollutants are very difficult to clean on-line. If the reverse osmosis membrane element is removed from the device and cleaned off-line, the ideal cleaning effect can be achieved, but it is time-consuming and labor-intensive, and the cost is high. Colloid, silt, fiber, iron manganese oxide, activated carbon particle pollution, how to quickly and effectively clean the reverse osmosis device to restore its operating performance is a very real problem

Abstract

The invention relates to a reverse osmosis system with a compressed air blowing function, belonging to the technical field of reverse osmosis water treatment systems. The reverse osmosis system with the compressed air blowing function comprises a reverse osmosis membrane pressure container, a water inlet pipe and a concentrated water discharging pipe, wherein the water inlet pipe is connected with the water inlet end of the reverse osmosis membrane pressure container; the concentrated water discharging pipe is connected with the water outlet end of the reverse osmosis membrane pressure container; and the reverse osmosis system is also provided with a gas inlet valve which is matched with the water inlet end of the reverse osmosis membrane pressure container. The reverse osmosis system has the advantages that the structural design is reasonable, effective and fast online cleaning can be realized, the cleaning effect is good, and normal use is not influenced.

Description

technical field [0001] The invention relates to a reverse osmosis system with compressed air purging function, belonging to the technical field of reverse osmosis water treatment systems. Background technique [0002] At present, the reverse osmosis system is an important equipment for desalination of water quality worldwide, and is widely used in the field of water treatment technology. However, it is inevitable that reverse osmosis membranes will be polluted during use. Especially in reverse osmosis systems that use reclaimed water and surface water as water sources, it is very common for reverse osmosis membranes to be polluted by organic matter, colloids, mud sand, fibers, iron-manganese oxides, and activated carbon particles. These pollutants are very difficult to clean on-line. If the reverse osmosis membrane element is removed from the device and cleaned off-line, the ideal cleaning effect can be achieved, but it is time-consuming and labor-intensive, and the cost is...
