Commissioning steps for purified water equipment

Purification water equipment debugging is divided into two parts, the first is the pretreatment debugging, and then the reverse osmosis host debugging part, the pretreatment debugging is mainly the positive and reverse washing quartz sand, activated carbon function test, observe whether fine sand charcoal and impurities can be washed away, followed by control the amount of water inflow, reverse osmosis host debugging is to adjust the inlet water, the flow of water and pressure test
.

Figure 1 The commissioning of the purified water equipment of Jingderui is summarized as follows: The first point: the input water of the device is analyzed and tested, and the results show that it meets the requirements of the water intake, and the device can be debugged after passing
.

The second point: adjust
the pressure control system of the high-pressure pump.

The third point: check whether the connection between all pipes of the device is perfect, whether the pressure gauge is complete, whether the low-pressure pipeline connection is tight, and whether there is a shortage
.

The fourth point: open the pressure gauge switch and the total inlet valve, concentrated water discharge valve, production water discharge valve
.

The fifth point: start the pretreatment equipment and adjust the water supply to be greater than the total water inlet of
the device.

The sixth point: the sand carbon filter is backwashed and forward-washed until the water is clear
.

The seventh point: start the high-pressure pump, and slowly open the total inlet valve of the device, the total inlet pressure of the control device is less than 0.
5Mpa, rinse for 5 minutes, and check whether the high and low pressure pipelines and instruments are normal
.

The eighth point: adjust the inlet valve and the concentrated water discharge valve so that the inlet water pressure reaches 1.
0~1.
4Mpa
.

The ninth point: test the water and electricity conductivity of the product, open the product outlet water valve when meeting the requirements, and close the production water discharge valve
.

The tenth point: the commissioning of the RO device is a manual single-step operation, which can be switched to the automatic state after normal operation, and then automatically controlled and operated
by the online instrument and PLC.

Point 11: Start the regeneration system to see if the regeneration system is working
properly.

The purpose of debugging is to ensure that the safety performance and functional performance of the equipment system can meet the design requirements and user expectations, and it is also one of the effective measures for us to promote the quality of the purified water equipment and ensure the safety of
the equipment.
