Household wastewater is hurting the environment more and more, therefore we need to discover ways to clean it that are cheap and last a long time. Using aquatic macrophytes like water hyacinth (Eichhornia crassipes) for phytoremediation is an excellent idea since they grow quickly, make a lot of biomass, and are better at soaking up contaminants. This study delineates the design and evaluation of a straightforward modular phytoreactor utilizing water hyacinth for the effective elimination of organic and inorganic pollutants from home wastewater. This research expands upon previous investigations focused on the extraction of phytochemicals such as shikimic acid, phenolics, and antioxidant compounds from water hyacinth, alongside lignin and cellulose from lignocellulosic materials. It stresses the benefits of cleaning up pollutants and using biomass in a way that adds value. We looked at the physicochemical and microbiological properties of wastewater samples and set up phytoreactor modules with set retention times. Water hyacinth was acclimatized and utilized in reactor units, with the efficacy of pollutant removal assessed by measuring the reduction in COD, BOD, nutrients (nitrogen, phosphorus), heavy metals, and microbiological loads. We used analytical tools like FTIR, HPLC, and spectrophotometry to help us keep an eye on things. The results showed that the water got better as time went on. A lot of minerals and organic substances were gone. Studies on the biomass of water hyacinth demonstrated the feasibility of recovering lignin, cellulose, and secondary metabolites, thereby endorsing the concept of a cyclical biorefinery model. The results show that modular phytoreactors provide a scalable, cost-effective, and long-lasting way to treat wastewater without the need for a central facility. They also aid with resource recovery and are excellent for the environment and the economy, which is what sustainable development is all about.
