Recently, I found that more and more people have begun to pay attention to knowledge sharing: what are the specifications and sizes of second-hand reverse osmosis membranes, and the following is a description of the relevant content, if you are more interested in this, you can come and learn about it.
Second-hand reverse osmosis membrane refers to the reverse osmosis membrane equipment that can be reused after use, after sufficient cleaning and maintenance. The following are the common specifications and sizes of second-hand reverse osmosis membranes and their brief introduction:
1. 8040 type film: The size of the film is 8 inches of outer diameter and 40 inches of length. Suitable for small water treatment systems such as domestic and commercial use. It is simple to operate, and the pretreatment filter needs to be cleaned and replaced regularly to ensure the performance and life of the membrane. Pressure vessels and pumps are recommended to control the inlet pressure.
2.Model 4040 Membrane: This membrane is available in dimensions of 4 inches of outer diameter and 40 inches of length. Suitable for medium-sized industrial water treatment systems. The operating process is similar to that of the 8040 membrane, but care should be taken to clean the membrane and replace the pretreatment filter regularly to ensure water quality and performance.
3.Type 8040ULP Membrane: This membrane is an ultra-low pressure reverse osmosis membrane that also measures 8 inches outside diameter and 40 inches in length. Suitable for applications that require energy savings, such as desalination and wastewater treatment. During the operation, it is necessary to ensure that the water supply quality meets the requirements and that appropriate pre-treatment measures are taken to extend the life of the membranes.
The process of operating a used reverse osmosis membrane generally includes the following steps:
1. Preparation: Check whether the instruments, pumps, valves and other equipment of the reverse osmosis membrane system are operating normally.
2.Opening system: Open the inlet valve, drain valve and booster pump in turn.
3.Pressure monitoring: During the operation of the system, monitor the pressure of influent and produced water to ensure that it is within the normal range.
4.Regular cleaning: According to the use situation, the cleaning and maintenance of the reverse osmosis membrane should be carried out regularly to ensure the performance and life of the membrane.
It is recommended to pay attention to the following points when operating second-hand reverse osmosis membranes:
1. Regularly inspect and replace the pretreatment filter to prevent impurities from entering the membrane system.
2.Control the inlet water pressure to avoid excessive pressure load on the reverse osmosis membrane.
3.Wash the membrane regularly to remove adhered dirt and sediment and maintain membrane performance.
4.According to the water supply quality and operation time, replace and update the second-hand reverse osmosis membrane in time to ensure the stability and efficiency of water quality output.
For the operation of second-hand reverse osmosis membranes, it is necessary to pay attention to regular cleaning and replacement of pretreatment filters and control of inlet water pressure to prolong the service life of the membrane. During use, the second-hand membrane is replaced in time according to the water quality and operation time. At the same time, it is necessary to follow the operating procedures and recommendations to ensure the stability and efficiency of water quality output.
