What should be paid attention to when the purified water equipment is operating?

Understanding the operation and management of purified water equipment is common sense for operation managers, which can effectively reduce the probability of failure when using the equipment, ensure system safety, and continuously and stably produce high-quality purified water
.

What should be paid attention to in the operation of purified water equipment? Figure 1 The first point of Jingderui purified water equipment is to strictly control the quality of the influent water to ensure the quality of the influent water.
The water source that does not meet the indicators enters the purified water equipment, which can easily cause the fouling of the membrane elements of the purified water equipment, which will seriously affect the water quality
.

The second point is that the water inlet of the reverse osmosis purified water equipment is controlled by the RO water inlet valve.
When the water inlet does not change, the regulating valve should not be mobilized at will, and at the same time, it should not be fully opened or fully closed
.

The RO concentrated discharge regulating valve is used to adjust the recovery rate of the system.
The regulating valve is the same as the former.
If the recovery rate does not change, it is not easy to mobilize the regulating valve and not fully open or fully close at the same time
.

The third point is that the purified water equipment is not easy to be shut down for a long time during the use process.
When encountering a situation that requires a short shutdown or a long shutdown, it is necessary to take appropriate protective measures
.

The fourth point, the temperature of the influent water, should be based on the actual water consumption, and the temperature at which the critical pressure (the pressure value at which the influent water pressure is lower than this value and the desalination rate will produce a significant drop) cannot meet the requirements of the produced water and water quality should be taken as the temperature within this time period.
Inlet water temperature, which can reduce the attenuation of membrane water volume
.

The fifth point, operating pressure control, should take the lowest possible pressure value under the premise of satisfying water production and water quality, which is beneficial to reduce the water flux attenuation of the membrane and reduce the replacement rate of the membrane
.

The sixth point, the operator records the operating parameters on time, and detects the use of the purified water equipment and the quality of the effluent
.

The main record content should include: Influent water: PH value, conductivity, pressure, SDI, water temperature
.

Produced water: conductivity, flow rate, PH value, concentrated water: flow rate, pressure and inlet water pressure of each section
.

The above are some of the things that need to be paid attention to during the operation of purified water equipment.
Understanding and mastering it can help us become more handy in the application of the equipment, improve work efficiency, and prolong the service life of the equipment
