The application process of graphene filters in the field of water treatment

The application process of graphene filters in the field of water treatment mainly includes the following steps:

1. Pretreatment: First, the water needs to be pretreated to remove large particle impurities and suspended solids to prevent them from blocking the graphene filter.

2. Filtration: Then, the pretreated water is filtered through the graphene filter. The graphene filter can effectively adsorb oil, heavy metal ions, organic pollutants, and microorganisms in the water.

3. Post-treatment: The filtered water may still contain some small particle impurities and soluble pollutants, which need to be post-treated, such as reverse osmosis, activated carbon adsorption, etc., to further improve the water quality.

4. Detection: Finally, the treated water needs to be detected to ensure that it meets the predetermined water quality standards.

5. Cleaning and Maintenance: After a period of use, the graphene filter may become blocked due to the adsorption of a large amount of pollutants, and it needs to be cleaned and maintained to maintain its filtration effect.
