Removal of Chromium from Batik Wastewater by Using Kenaf (Hibiscus cannabinus L.) with Bed Evapotranspiration

Abstract

Wastewater treatment using plants is being applied by researchers to its capability in metal removal. Technologies are using plants for treatment as a green technology. Phytotreatment is a technology using plants that can reduce organic and inorganic pollutants in the environment. Kenaf (Hibiscus cannabinus L.) is terrestrial plants that can be used in the phytotreatment process because they can reduce pollutants. The aim of this study was to remove chromium from batik wastewater. This experiment used bacth system in bed evapotranspiration. Variables used were kenaf plant varieties (KR 11 and KR 15), kenaf plant age (30 days and 45 days), and batik wastewater concentration. This research was conducted for 28 days. The specific response of kenaf plants is indicated by the growth of kenaf, the increase in plant height and the number of leaves in the batik wastewater treatment. The most removal of chromium was found 66,49 %. The results showed that Kenaf can be used for phytotreatment agent to removal of chromium.
