A review of vermifiltration and related low cost alternatives for waste water management

Vermifiltration is a treatment method that combines the conventional filtration processes with the vermicomposting techniques. It has opened new grounds for treating wastewater in the world, and especially so in the developing countries due to its low cost and eco-friendly nature. Research is ongoing in this area since the field has gained attention from the scientific community only recently. Water resource management system has been in the limelight for a while now, more so in the case of developing countries, which face multidimensional issues when it comes to managing waste water as well as existing water sources. This paper is an attempt to analyze and review the published research that has been carried out so far in this discipline, and bring to fore factors that should be adequately understood and addressed when designing vermi-biofiltrationunits.
