Abstract: Delhi is a key center for industry, trade, and production as the country's capital. Due to heavy metals pollution's longevity, scientists are becoming interested in phytoremediation; a low-cost, ecologically friendly plant-based remediation approach. This study aims to see how effective plant species canna lilly (C. indica) grown in a hydroponic system using different concentrations for removing heavy metal s (Cr, Cu, Fe, Pb, and Zn) from integrated industrial wastewater (IIWW). The test plants were placed in five different troughs containing 100%, 80%, 60%, 40% of IIWW, and a control trough (tap water) and conducted study for 25 days. The results suggest that C. indica has the maximum heavy metal reduction efficiency at 80% from IIWW. Besides this, the Bioconcentration factor (BAF) and translocation factor results were also recorded at 80% of IIWW concentrations. The plant attributes in terms of root and shoot plant length and fresh weight and dry weight (root and shoots) of C. indica was significantly (P
