ClearMembrane fouling characteristics and mechanisms in coagulation-ultrafiltration process for treating microplastic-containing water
This study investigated how microplastics affect membrane fouling during a common water treatment process that combines coagulation with ultrafiltration. Researchers found that while microplastics initially worsen membrane fouling, adding the right amount of coagulant can actually turn the plastics into an advantage by creating a looser filter cake that improves water flow.
