Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically a reverse osmosis membrane cleaning device. Background Technology

[0002] Reverse osmosis membranes are semi-permeable membranes with high-efficiency separation capabilities. Under pressure, they allow water molecules to pass through while retaining most of the salt, bacteria, viruses, organic matter, and other impurities in the water, thereby achieving deep purification and desalination of water. They are widely used in seawater desalination, drinking water purification, and other fields.

[0003] During operation, reverse osmosis membranes trap various impurities in the water, such as suspended solids, colloids, microorganisms, organic matter, and inorganic salts. Therefore, they need to be cleaned using a cleaning device. However, the cleaning tanks in traditional reverse osmosis membrane cleaning devices are not easy to control the ratio of chemicals, resulting in uneven chemical composition of residual chemicals in the water after cleaning. At the same time, it is not easy to recycle the cleaning water, causing a huge waste of water resources. Especially in water-scarce areas, this waste will exacerbate the water shortage situation.
