Vetiver Floating Wetlands for Dyeing Effluent

Abstract

As a result of industrialization, the degree of global water contamination has drastically grown in recent decades. Both rich and developing nations are seeing this worldwide trend, although the later are experiencing it more pronouncedly. Due to its extraordinary and distinctive morphological and physiological characteristics, the Vetiver Floating Wetlands (VFWs), which is based on Vetiver grass (Chrysopogon zizanioides), has been successfully used as a phytoremediation tool to remediate both polluted water like municipal wastewater such as sewage effluent, landfill leachate, urban runoff, drainage channels, industrial wastewater such as food processing factories, and contaminated land (mine overburden and tailings, solid waste dumps). This study focuses on the use of hydroponics and floating wetlands to clean contaminated dyeing effluent. This study aims to find the efficiency of Vetiver Floating wetlands over various physio-chemical parameters in Dyeing effluent. The study was laid down in Tamil Nadu Agricultural University, Coimbatore in 2022 during the month of April- May. The effluent was diluted to different concentrations namely 25%, 50%, 75% and 100%. Various parameters were analyzed in these treatments in Dyeing effluent. The samples were collected at 15 days interval analyzed for one month. In Dyeing effluent, 50% concentration of the effluent showed better results over Vetiver Floating Wetlands and the removal efficiency was greater at this particular concentration.
