Reuse potential of textile dyeing wastewater through vermifiltration

Study was conducted to explore the reuse potential of the textile dyeing wastewater generated from textile dye industry. Earthworms proved to be master bio processing agents for the management of organic effluents from diverse sources ranging from domestic sewage to industrial refuse. In this context, the present paper describes the application of vermiculture based wastewater technology with the primary objective of converting liquid effluent into eco-friendly safe water. Vermifiltration of wastewater using waste eater earthworms is a newly conceived novel technology. The biological oxygen demand (BOD5), chemical oxygen demand (COD), total dissolved solids (TDS) and total suspended solids (TSS) decreased by 85-89%, 76-80%, 73-77% and 71-76% respectively through vermifiltration.
