Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a reverse osmosis membrane filtration system for water treatment. Background Art

[0002] In the prior art, reverse osmosis is a membrane separation technology with pressure as the driving force by means of the function of a selectively permeable (semi-permeable) membrane. When the pressure applied to the system is greater than the osmotic pressure of the influent solution, water molecules continuously pass through the membrane, flow into the central pipe through the product water flow channel, and then impurities in the water, such as ions, organic substances, bacteria, viruses, etc., are retained on the influent side of the membrane and then flow out at the concentrated water outlet end, so as to achieve the purpose of separation and purification. The reverse osmosis water purification system is a system that uses reverse osmosis technology for water purification treatment. Usually, the reverse osmosis water purification system includes a pretreatment device, a pressurization device, and a reverse osmosis water system. The above three devices are connected in series in sequence to form the entire reverse osmosis water purification system. The pretreatment device is used to filter larger particulate matter in the raw water to ensure that the water quality can meet the influent requirements of the reverse osmosis membrane filtration; the pressurization device is used to increase the influent pressure of the reverse osmosis membrane filtration device to ensure the water production rate of the reverse osmosis membrane filtration device; after the raw water passes through the reverse osmosis membrane filtration device, it will be divided into purified water and concentrated water. The purified water can be directly used or stored for standby, and the concentrated water is usually directly discharged into the sewer pipe or reserved for other uses. The existing reverse osmosis water purification system usually uses a group of security filters for single-stage pretreatment of raw water, which cannot effectively remove impurity particles, and the purification effect is poor. If the number of security filters is increased, it will affect the maintenance space of the reverse osmosis system when the layout environment is limited, and cannot meet the installation requirements of the filtration system.

[0003] The Chinese utility model patent with the application number 202220929556.9 discloses a reverse osmosis water treatment system, including a group of pretreatment systems and two groups of reverse osmosis water systems. The pretreatment system includes a raw water pump, a filter tank group, a soft water tank inlet solenoid valve, and a soft water tank connected in sequence. The soft water tank is connected to the two groups of reverse osmosis water systems through two water outlets respectively. The reverse osmosis water system includes a soft water pump, a security filter, an inlet valve, a low-pressure switch, a high-pressure pump, an RO membrane filter group, a pure water tank, and an output pump connected in sequence, and the water outlets of the two pure water tanks are connected. However, the structure of this reverse osmosis water treatment system is relatively complex, and its various parts are scattered, resulting in that this water treatment system will affect its maintenance space when the layout environment is limited and cannot meet the installation requirements of the water treatment system.
