How to maintain the purified water equipment when it is out of service?

Purified water equipment can effectively supply standard water sources for pharmaceutical production lines.
It is a basic condition to choose a set of excellent equipment and to cooperate with later standard operation and correct maintenance.
In order to help you better manage the operation of equipment, today Xiaobian will introduce to you.
How to maintain the pharmaceutical purified water equipment when it is out of operation
.

If the pharmaceutical purified water equipment is planned to be out of use for more than 30 hours, the cleaning system can be used to protect it from shutdown: 1.
Prepare a formaldehyde solution with a concentration of 0.
5-0.
7% with the water of the pharmaceutical purified water equipment, and adjust the pH to 5-6 between
.

2.
Start the cleaning water pump and flush the reverse osmosis at a flow rate of 45-58m3/h
.

3.
Sampling and testing from the reverse osmosis concentrated water discharge, when the formaldehyde content reaches 0.
5%, the flushing water pump can be stopped
.

　　4.
Close all inlet and outlet doors of the pharmaceutical purified water equipment to ensure that the system is filled with qualified formaldehyde solution
.

　　5.
When the long-term outage protection of the pharmaceutical purified water equipment exceeds 30 days, the above items 1-4 should be repeated to ensure the safety of the equipment
.

The reverse osmosis membrane element should be stored in an environment with a temperature above 0oC
.

　　6.
When the pharmaceutical purified water equipment is put into use again, flush the system with low-pressure feed water for 0.
5-1h, and then flush the system with high-pressure feed water for 5-10 minutes.
Regardless of low-pressure or high-pressure flushing, the water discharge valves of the system should all be opened
.

Before restoring the pharmaceutical purified water equipment system to normal operation, it should be checked to confirm that the product water does not contain any biocides
.

      The maintenance work of the pharmaceutical purified water equipment under different operating conditions is slightly different.
