Abstract

The invention discloses a system and a method for testing the influences of an electromagnetic field on the separation performance of a reverse osmosis membrane, belonging to the technical field of the liquid separation membrane water treatment. The invention can be used for solving the problem of the large seawater desalination system that as the parameters of the electromagnetic field are debugged and the proper reverse osmosis membrane is selected, the cost is increased and the testing time is prolonged. The test system comprises a constant temperature circulation water tank, a test pool, a high-pressure pump, a first pressure gage, a second pressure gage, a first valve, a second valve, a first flowmeter, a second flowmeter, a third flowmeter, a fourth flowmeter, a first conductivity meter, a second conductivity meter and an electromagnetic field generating device. The test method is based on the test equipment; and the penetrating fluid flux of a penetrating fluid loop and the desalination rate are calculated according to the variable data of each metering element under a non-electromagnetic field environment and an electromagnetic field environment to obtain the influences of the electromagnetic field on the separation performance of the reverse osmosis membrane. The test system and test method are suitable to be used to test the influences of the electromagnetic field on the separation performance of the reverse osmosis membrane.

Description

technical field [0001] The invention relates to a test system and a test method for the influence of an electromagnetic field on the separation performance of a reverse osmosis membrane, and belongs to the technical field of liquid separation membrane water treatment. Background technique [0002] At present, there are five methods of seawater desalination: multi-stage flash (MSF), reverse osmosis (RO), multi-effect distillation (ME), compressed vapor distillation (VC) and electrodialysis (ED). The osmosis method has quickly occupied the market due to its advantages of simple equipment, low investment, low energy consumption, short construction period, easy maintenance and equipment modularization, and has gradually replaced distillation as the most widely used seawater desalination method. [0003] The reverse osmosis membrane used in the reverse osmosis method is often polluted or deteriorated due to fouling and corrosion, which increases the replacement and maintenance co...
