Abstract

Abstract: With global population explosion, the available water resources are slowly being polluted due to the excessive human interference. To encounter this, it is the need of this hour to find out sustainable pollution remediating technologies to meet the stringent discharge standards for domestic as well as industrial wastewaters. In addition, those techniques should have the capabilities for effective implementation even in developing countries. Based on the available literatures, one such technique, named vermifilter, has been identified which takes care of almost all the sustainable and economical criteria for its effective implementation even in developing countries. The aim of this meta-analysis is to provide a comprehensive review on assessment mechanisms involved, factors affecting the process and performance of vermifiltration under different scenarios. The present review envisages the current state of the knowledge regarding physical, chemical and biological aspects related to the treatment mechanisms and effective functioning of earthworms. This review has also proposed several suggestive plans on its application at any proposed site. Highlights: The review exhaustively outlines the mechanisms involved in vermifiltration. Factors affecting vermifiltration have been identified and discussed critically. Application of vermifiltration for industrial wastewater has also been advocated. It also discusses properties and application of harvested compost from vermifilter. Growth and reproduction of earthworms in the vermifilter has also been discussed.
