Treatment of kitchen wastewater by Phytoremediation method by canna indica plant

Abstract: This report details a project focused on developing a sustainable, low-cost, and eco-friendly method for treating domestic kitchen wastewater using the principles of phytoremediation. Kitchen wastewater, a major component of household greywater, poses an environmental challenge due to its high concentration of organic matter, nutrients, and suspended solids, indicated by elevated Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Suspended Solids (TSS). Conventional treatment systems are often energy-intensive and cost-prohibitive for decentralized application.The core objective of this study was to evaluate the efficiency and suitability of the wetland plant, Canna indica (Indian Shot), as the primary phytoremediation agent. The project sought to analyze changes in key water quality parameters ( PH, BOD, COD, and TSS) before and after treatment, and to develop a functional, low-cost treatment system.
