What should be paid attention to in the operation of purified water equipment?

In addition to the good performance of the equipment itself, the long-term stable operation of the purified water equipment is the correct operation and maintenance during use.
Therefore, it is necessary to understand what needs to be paid attention to in the operation of the purified water equipment and avoid wrong operations in order to effectively ensure the purified water equipment.
stable operation
.

Matters needing attention during the operation of purified water equipment: 1.
Strictly control the quality of the influent water to ensure that the water source that does not meet the indicators cannot enter the purified water equipment, otherwise it will easily cause the fouling of the membrane elements of the purified water equipment, which will seriously affect the effluent quality
.

2.
The water intake of the reverse osmosis purified water equipment is controlled by the RO water inlet valve.
If the water intake does not change, do not tamper with the water inlet regulating valve, and it is strictly forbidden to open or close it fully
.

The RO concentrated discharge control valve is used to adjust the recovery rate of the system.
If the recovery rate does not change, do not tamper with the concentrated discharge control valve, and it is absolutely forbidden to fully open or close it
.

3.
Purified water equipment is not easy to shut down for a long time.
If it is ready to shut down for more than 72 hours, use chemical cleaning device to fill the components with 1% sodium hydrogen sulfate and 18% glycerin for protection
.

　　4.
The temperature of the influent water should be controlled according to 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 influent water in this period of time.
temperature, which can reduce the attenuation of the membrane water volume
.

　　5.
When the high and low pressure alarm occurs in the reverse osmosis purified water equipment, first check whether the opening of the manual valve between the security filter and the high pressure pump is too small, then check whether the RO water inlet control valve and the concentration discharge valve are normal, and then press the high The low pressure alarm reset button restarts the pure water production equipment
.

　　6.
The reverse osmosis purified water equipment should be flushed for 10 minutes under the condition that the inlet water pressure is less than 0.
4Mpa when it is started after each shutdown
.

　　7.
For operating pressure control, the lowest possible pressure value should be taken under the premise of satisfying water production and water quality, which is conducive to reducing the water flux attenuation of the membrane and reducing the replacement rate of the membrane. .

　　8.
The operator should record the operating parameters every hour, and check the usage 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 the specific operation precautions of purified water equipment.
The editor reminds the operators of purified water equipment that they must master it accurately, so as to promote the good operation of the equipment and achieve an excellent water supply effect
.

In addition to mastering the precautions for the operation of purified water equipment, the maintenance of purified water equipment is also the basic condition to promote the stable operation of the equipment
