Toxic metals are produced and dumped into water supplies by various anthropogenic activities, for example, industrial effluents, making them inaccessible and threatening human health. Conventional chemical precipitation and membrane filtration are two methods for elimination of toxic elements and are exceedingly costly when treating large amounts of water, and ineffective at low metal concentrations (incomplete elimination) can produce large amounts of sludge and other harmful compounds, which necessitate disposal with care. Biosorption is environmentally acceptable option that offer advantages over other methods. Natural and other agro-based materials that are abundant, such as microbial agro-wastes, biomass, and industrial leftovers, have been proposed as suitable biosorbents for heavy metal removal. Temperature, pH, metal ion concentration, biosorbent dose, and agitation speed are all factors that influence biosorption. Before usage, the biomass might be chemically and physically altered. By renewing and recycling the biosorbent after it has removed heavy metals from wastewater, the process can be made more cost-effective. Various bioreactors could be used to eliminate toxic metal ions from large volumes of effluents or water in biosorption. In biosorption, a variety of bioreactors can be used to remove metal ions from huge volumes of effluents or water. The current study looks at the future potential of textured vegetable protein (TVP) or Soya Chunks in the biosorption of industrial effluent, with a prime focus on Chromium and Lead.
