Do you know these points? Recently, I found that many people don't know much about this, so this article will briefly introduce the relevant content:
Old RO membranes refer to reverse osmosis membranes that have deteriorated or are no longer suitable for use after a period of use. Here are a few things you need to know about the old RO membranes:
1. *Process: Old RO film** generally includes collection, cleaning, repair and reuse processes.
Collection: Used RO membranes are typically used by water treatment equipment manufacturers, operators, or owners of demolition projects, etc.**. The collection can be in a box, a centralized point or by mail, etc.
Cleaning: The old RO membrane needs to be cleaned to remove dirt, sediment and impurities. Cleaning can be done using physical, chemical, or biological methods to ensure that the membrane surface is clean.
Repair: After cleaning, the old RO membrane needs to be repaired to restore its performance. Repair involves patching, replacing, or updating membrane elements so that they can be used again.
Reuse: The repaired old RO membranes can be resupplied to water treatment equipment manufacturers or users in the market for the manufacture of new equipment or to replace membrane elements in existing equipment.
2.Whereabouts: The old RO film may have different destinations depending on the situation.
Reuse: The repaired old RO membrane can be reused in water treatment equipment and supplied to the market where RO membranes are needed. Reusing old RO membranes can reduce the waste of resources, reduce costs, and have a good impact on the environment.
Sludge treatment: Some old RO membranes that cannot be repaired or are no longer fit are sent to a dedicated treatment facility for sludge treatment to ensure that they do not have a negative impact on the environment.
Materials: Materials such as plastics, metals, etc. in the old RO film can be utilized. Through a suitable treatment process, these materials are separated and converted into raw materials that can be reused.
The old RO membrane** process includes steps such as collection, cleaning, repair, and reuse, which may be reuse, sludge treatment, or materials**. These measures can reduce the waste of resources, reduce costs, and have a positive impact on the environment.
