During this time, I checked my friend's reply and found that many friends are not very clear about the realization of the second use of the old RO film.
*The reuse of old RO membranes is an environmentally friendly measure aimed at reducing waste generation and improving resource utilization at the same time. Here's a quick rundown of the process:
1. Process:
a.Collection: Collect discarded old RO membranes. This can be done by working with an engineer who treats the wastewater or by liaising with the relevant waste treatment company.
b.Sorting: Next, the collected old RO membranes are sorted. This can be categorized based on factors such as the condition, age, and performance of the membrane for subsequent processing.
c.Detection: The sorted old RO film is tested to determine if it is still suitable for secondary use. This can include membrane performance testing, cleaning tests, and other processes.
d.Repair cleaning: If the old RO membrane still has some usable value, a repair or cleaning process can be performed to restore the performance and function of the membrane. This can include cleaning dirt from the membrane surface, repairing damage on the membrane, etc.
e.Secondary use: The repaired or cleaned RO membrane can be reused. They can be reinstalled in water treatment systems to continue to filter and separate impurities.
2.Where to go:
a.Reuse: Old RO membranes can be reused after repair or cleaning. They can be applied to various water treatment systems, such as reverse osmosis equipment, pure water equipment, etc., for purifying or filtering water sources.
b.Sales: The repaired old RO membrane can be sold to other businesses or individuals who need water treatment. This extends the service life of the old RO membrane and maximizes its value.
c.Detoxification: For those old RO membranes that cannot be repaired or cleaned, they can be sent to a dedicated waste treatment facility for detoxification. This can include membrane incineration, landfilling, and other disposal methods to prevent pollution to the environment.
Through the ** and reuse of old RO membranes, resource waste can be reduced, environmental pollution can be reduced, and costs can be saved. However, in order to ensure the quality and effectiveness of the old RO membrane, it needs to be rigorously tested and treated. At the same time, it is also necessary to establish a comprehensive first-class system to ensure that the old RO membranes can be collected, sorted, disposed of and reused smoothly.
