Abstract：This paperfirstanalyzes the preparation processesof several mature filter media，including natural biofilm formation，biologicalfiltration membranes，iron-manganeseoxidecoatings，andother modified filter materials.Itthen focusesondetailing thefilmformationmethods forbiologicalfiltrationmembranesandiron-manganeseoxidecoatings，the modificationprocessesofconventional filtermedia，andtheircorresponding treatmenteficiency.Finalythemhanisms underlying the performance of different filter materials are systematically examined.
