Evaluating The Potential of Hibiscus Rosa-Sinensis in Floating Wetland for The Remediation of Water Bodies Polluted with Domestic Sewage

Abstract

The inadequate infrastructure for wastewater treatment in many regions has led to the contamination of surface water bodies and groundwater degradation. To address this issue, floating wetland treatment systems have emerged as a viable alternative for effective wastewater remediation. This study focuses exclusively on utilizing Hibiscus rosa-sinensis, a tropical ornamental plant, within the context of floating wetland treatment techniques for the remediation of domestic wastewater. The primary objective is to assess the nutrient and pollutant removal efficiency of Hibiscus rosa-sinensis in a laboratory-scale floating wetland system. Healthy Hibiscus rosa-sinensis plants were cultivated on identical floating rafts and placed in plastic tanks filled with domestic sewage for experimental investigation. Water quality analyses were conducted regularly, spanning 0, 3, 5, 10, 15, 20, and 25 days HRT. The results of this experimental investigation revealed that Hibiscus rosa-sinensis, when used in floating wetland treatment, exhibited significant removal efficiencies for various parameters, including turbidity, total suspended solids (TSS), total phosphorus (TP), ammonia, and dissolved oxygen (DO).These findings highlight the potential of Hibiscus rosa-sinensis plants as a practical component of floating wetland systems for removing nutrients and pollutants from domestic wastewater. This research underscores the viability of Hibiscus rosa-sinensis as a sustainable and environmentally friendly solution to address water pollution challenges, particularly in the context of floating wetland treatment.
