Now a days waste water treatment processes are costly, need more space for the construction of treatment plant & use of chemical for the treatment. We need some more options at low cost, space saving and eco-friendly techniques. Centralized treatment involve problem of high cost collection, treatment & disposal of wastewater which needs for small scale decentralized eco-friendly alternative treatment options Vermifiltration is one of the ecofriendly, low cost, chemical free technique used to treat the wastewater using the Eiseniafetida earthworm species. The present paper review describes the vermifiltration mechanism for removal of various pollutants from wastewater such as pathogen, organics and nutrients. In addition to this, effect of various parameters on treatment process like feeding mode, hydraulic loading rate, earthworm density, filter media, organic carbon source, etc. have been discussed briefly.
