Daily maintenance of membrane system
2023/09/08
Once the membrane system is put into operation, theoretically it should continue to operate continuously under stable operating conditions. In fact, it is necessary to frequently start and stop the operation of the membrane system. Each start and stop involves a sudden change in system pressure and flow rate, which generates mechanical stress on the membrane components. 因此，应尽量减少系统设备的启动和停止的次数，正常的启动、 停止过程也应该越平稳越好，启动的方法原则上应与首次投运的步骤相同。
Symptoms after membrane system contamination

Firstly, the conductivity of the water produced in the second stage of the membrane system is abnormal (with an increase in conductivity), resulting in a significant decrease in water production and a gradual increase in pressure. The pressure difference in the second stage also gradually increases. The most significant symptom is a significant decrease in water production.

The conductivity of the produced water in the membrane system is very sensitive to changes in the inlet temperature. As the water temperature increases, the viscosity of the water molecules passing through the membrane decreases and the diffusion ability increases, resulting in a linear increase in water flux. Increasing the water temperature will lead to a decrease in desalination rate or an increase in salt permeability, mainly because the diffusion rate of salt through the membrane will accelerate due to the increase in temperature.

What precautions should be taken when starting the system for the first time
2023/09/08
To ensure that the system operating parameters meet the design parameters, the water quality and yield of the system meet the design goals, and to prevent damage to the membrane due to exceeding the limit of inflow flow and pressure or water hammer, it is necessary to operate in the correct startup sequence. Before starting the system, on the premise of ensuring that raw water does not enter the components, check each item according to the pre startup inspection items. Thoroughly rinse the pre-treatment part of the raw water, flush out impurities and other pollutants, and prevent them from entering the high-pressure pump and membrane components. Especially, check whether the SDI15 value of the pre-treatment effluent is qualified, and whether the inlet water contains no residual chlorine or other oxidants;
