Biosorption is an environmental friendly method for metal removal as it can be used as a cost effective and efficient technique for heavy metal removal. A lot of biomass can be choosed as biosorbent such as waste material from food processing and agriculture.ent. This paper will review the potential used of local fruit rind as biosorbent for heavy metal removal in wastewater. Heavy metals have been in various industries and resulted to a toxic condition in aquatic ecosystem. Therefore, various techniques have been employed for the treatment of metal-bearing industrial wastewaters including biological treatment through biosorption. Biosorption offers the advantages of low cost, good efficiency and production of sludge with high metal content is possible to avoid by the existence of metal recovery method from metal loaded biosorbent. The successful application of local fruit waste in treating wastewater containing heavy metals requires a deeper understanding of how biosorbent material proceeds.

Wastewater Purification

This study uses naturally growing water hyacinth for wastewater purification system, this is an alternative technique of heavy metal remediation. These plants enhance the removal of pollutants by consuming part of them in the form of the plant nutrients. The vascular plants cultured in such treatment system perform several functions, including assimilation and storing contaminates, transporting O2 to root zone, and providing a substrate for microbial activity, canal containing floating macrophytes. This applies to municipal wastewater, in particular, where treatment units of different size can be applied at the pollution source and consumes less energy for the running. The effectiveness of wastewater purification by different plants was tested on laboratory and pilot scales. The aquatic plants system offers an environmentally friendly and cost effective technology, which have been used for removing Cadmium, Iron and Copper from wastewater. Batch experiments verified that the plants are capable of decreasing all tested indicators for water quality to levels that permit the use of purified water for irrigation, which poses serious problems in various locations throughout the country. It is shown that mixture of wastewater from in front of Gautam Budha University canal/ Greater Noida’s canal wastewater and Galgotias University sewage treatment plants. The removal efficiency of the Cadmium, Iron and Copper is 74.52%, 75.31% and 67.75% in greater Noida’s canal and 73.72%, 74.99 % and 68.37% in Galgotias University’s wastewater respectively.

Nowadays, undisputable environmental pollution requests endeavors to treat wastewater, particularly containing heavy metal, where wastewater treatment technologies are improving hastily. Hydroxyapatite with micro-porous structure and the large surface area turns into an intense research topic as of its high adsorption capacity. Environmentally friendly Hydroxyapatite powder with the large specific surface is a promising cost-effective precipitation method, for the removal of heavy metals (Al, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) from wastewater. Different studies have revealed the efficient removal of all metals using hydroxyapatite or by modified HA using zeolite or chitosan. The increase of Ca2+ ions content in the treated water suggests an ion exchange mechanism

AbstractAbstract Heavy metals, derived from industrial wastewater discharge, present a serious threat to human health and to natural water. Biosorption is regarded as a cost-effective biotechnology for the treatment of high volume and low concentration wastewaters containing heavy metal(s) in the order of 1 to 100 mg L−1. Among the biomaterials for heavy metal removal which have been researched during the past decades is the Streptomyces species, a by-product of an industrial antibiotic fermentation process. This paper describes the hazards posed by heavy metals effluents on the environment and use of various Streptomyces species to remove heavy metals from aqueous solution. Characterization of Streptomyces species, factors affecting biosorption, biosorption isotherms and biosorption kinetics is discussed. Graphical abstract

Heavy metals are a noxious form of pollutants present in soil and water. A new plant-based solar energy driven technology, phytoremediation, emerges as eco-friendly and cost-effective approach to remove heavy metal from various media with the help of hyperaccumulating plant species. This review paper aims to provide information on phytoremediation and its mechanisms for heavy metal removal especially to focus on Cadmium (Cd) metal and highlights the role of various hyperaccumulating plants for Cd metal remediation in soil and water. It complies various field case studies which play the important role in understanding the Cd removal through various plants. Additionally, it pinpoints several sources and the effects of Cd and other technologies used for Cd remediation. This paper provides the recent development in mechanisms of Cd hyperaccumulation by different plants, in order to motivate further research in this field.
