The invention adapts to the technical field of a reverse osmosis membrane test, and provides a method and apparatus for testing a reverse osmosis membrane. The method comprises: pouring a target testliquid to a reverse osmosis membrane according to a preset inlet water pressure, and allowing the reverse osmosis membrane to filter the target test liquid to obtain purified water; obtaining attribute parameters including at least one of salt rejection, purified water flow rate and purified water recovery rate when the reverse osmosis membrane filters the target test liquid; and determining whether the reverse osmosis membrane meets the preset standard according to the attribute parameters. According to the embodiment, a target test liquid is poured to the reverse osmosis membrane according to a preset water pressure, the target test liquid is filtered to obtain purified water through the reverse osmosis membrane, attribute parameters are obtained when the reverse osmosis membrane filtersthe target test liquid, and whether the reverse osmosis membrane meets the preset standard is determined according to the attribute parameters. The reverse osmosis membrane test process becomes simple and is easy to achieve.
Description
technical field [0001] The invention belongs to the technical field of testing reverse osmosis membranes, in particular to a method and device for testing reverse osmosis membranes. Background technique [0002] As people's needs and awareness of maintaining their own health continue to increase and improve, related products are also favored by consumers. For example, air purification devices, water purification devices, etc. [0003] In the water purification device, the quality of the reverse osmosis membrane directly affects the water purification efficiency of the water purification device. Although in the prior art, it is possible to judge whether the parameters of the reverse osmosis membrane are qualified by testing the air tightness of the reverse osmosis membrane, but the test method needs to calculate the air tightness data of the reverse osmosis membrane during the implementation process. , the implementation process is more complicated.
