Reverse osmosis water treatment technology is usually used to treat related water quality problems. The structure of reverse osmosis water treatment equipment is relatively complex and has many functions. Now, Xiaoke will take you to understand the main working principle of reverse osmosis water treatment equipment?
Reverse osmosis water treatment technology is commonly used for desalination of seawater and brackish water, water softening treatment, wastewater treatment, as well as purification, concentration, and separation in the food and hospital industries. In addition, the application of reverse osmosis technology in desalination pretreatment has also achieved good results, mainly reducing the load of ion exchange resin by more than 91% and the regeneration metering of resin by 90%. Therefore, it not only saves costs but also benefits the environment. Reverse osmosis technology can also be used to remove particles, organic matter, and colloidal substances in water, which has a good effect on reducing the pollution and extending the life of ion exchange resin
The combination forms of reverse osmosis membranes include: (1) multi-stage series treatment. When the salt content in the water source is high and the requirements for the quality of reverse osmosis effluent are also high, a multi-stage series connection method can be used, where the first stage effluent is used as the second stage inlet. Under this treatment method, the water quality of the second stage's discharge (concentrated water) is much better than that of the first stage's inlet water, and can be mixed with the first stage's inlet water as the inlet water. In several stages of series connection, relevant components such as an intermediate water storage tank and a high-pressure pump are required. （2） Multi segment combination processing. When the salt content in the water source is not very high, a multi-stage combination can be used to achieve a higher return water rate. The concentrated water from the first section enters the second section as the inlet, and the permeate water from both sections is mixed as the product water. If necessary, an additional section can be added, where the second section of concentrated water is used as the inlet for the third section, and the permeate water from the third section and the effluent from the first two sections are combined to form product water. This has the advantages of reducing water consumption and increasing return water rate. （3） The three-stage connection method with an intermediate booster pump is more suitable for places with scarce water sources because of the requirement to save water. Therefore, even if the water quality is poor and the salt content is high, it is hoped to achieve a relatively high return water rate. Therefore, in the combination of multiple sections, due to the high salt content of each stage's inlet water, a high-pressure pump must be placed to ensure that the pressure difference reaches the required value.
