Rhizofiltration is a form of phytoremediation that involves filtering water through a mass of roots to remove toxic substances or excess nutrients. Rhizofiltration is a kind of phytoremediation, which alludes to the approach of utilizing hydroponically developed plant roots to remediate debased water through assimilation, focus, and precipitation of contaminations. It likewise channels through water and earth. The sullied water is either gathered from a waste site or conveyed to the plants, or the plants are planted in the debased zone, where the roots at that point take up the water and the contaminants broken up in it. Many plant species actually take-up substantial metals and abundance supplements for an assortment of reasons: sequestration, dry season resistance, transfer by leaf abscission, obstruction with different plants, and protection against pathogens and herbivores. Some of these species are superior to others and can collect unprecedented measures of these contaminants.

Distinguishing proof of such plant species has driven ecological specialists to understand the potential for utilizing these plants for remediation of debased soil and wastewater. Rhizofiltration might be appropriate to the treatment of surface water and groundwater, modern and private effluents, downwashes from electrical cables, storm waters, corrosive mine seepage, farming overflows, weakened mucks, and radionuclide-debased arrangements. Plants reasonable for rhizofiltration applications can productively expel harmful metals from an answer utilizing fast development root frameworks. Different earthly plant species have been found to viably expel lethal metals, for example, Cu2+, Cd2+, Cr6+, Ni2+, Pb2+, and Zn2+ from watery solutions. It was likewise discovered that low level radioactive contaminants can effectively be expelled from fluid streams.
