How to maintain the reverse osmosis membrane in the integrated stainless steel pure water treatment equipment? Author: integrated stainless steel reverse osmosis membrane water treatment equipment if not used immediately after unpacking or in use for some time will be related to maintenance issues, if maintenance shall not be treated, will result in the reverse osmosis membrane performance Impact, the following editor will introduce how to maintain the reverse osmosis membrane in the integrated stainless steel pure water treatment equipment. 1. The system will be shut down in a short period of time (1-3 days): Before shutting down, the system should be flushed with low pressure (0.2-0.4MPa) and large flow (approximately equal to the water output of the system) for 14-16 minutes; keep it The normal natural water flow allows the water to flow into the thick water channel. 2. The system is shut down for more than one week (ambient temperature is above 5℃): Before shutting down, the system should be low-pressure (0.2-0.4MPa) and large flow (approximately equal to the production water volume of the system (flushing, time is 14-16 minutes) ; Perform chemical cleaning according to the chemical cleaning method of the system in the operating instructions of the reverse osmosis system; after the chemical cleaning is completed, rinse the reverse osmosis membrane; prepare 0.5% formalin solution, enter the system at low pressure, and circulate for 10 minutes; close all The valves of the system should be sealed; if the system is out of service for more than 10 days, the formalin solution must be replaced every 10 days. 3. The ambient temperature is below 5°C: Before shutting down, the system should be under low pressure (0.2-0.4) MPa), flush with a large flow (approximately equal to the water production of the system), and the time is 14-16 minutes; where conditions permit, the ambient temperature can be raised to above 5°C, and then follow the method 1 to perform system maintenance; if To increase the ambient temperature unconditionally, then: low pressure (0.1MPa), a long flow of water with a flow rate of 1/3 of the system's water output, to prevent the reverse osmosis membrane from being frosted, and to ensure that the system runs for 2 hours a day; In the method of (2) and (3) in 1, after cleaning the reverse osmosis membrane, take out the reverse osmosis membrane, move it to a place where the ambient temperature is greater than 5℃, and soak it in a prepared 0.5% formalin solution , Turn over once every two days, and the water in the system pipes should be drained clean to prevent damage to the system due to icing. This is the introduction of how to maintain the reverse osmosis membrane in the integrated stainless steel pure water treatment equipment. In order to ensure the performance of the reverse osmosis membrane, it is best to maintain it in accordance with the above content, and the reverse osmosis membrane should be unpacked during use. Do not unpack it in advance, otherwise the performance of the reverse osmosis membrane of the ultrapure water equipment will be reduced. Wait for a lot of influence.
