Download or read book Demonstration of Removal Separation and Recovery of Heavy Metals from Industrial Wastestreams Using Molecular Recognition Technology MRT written by Katherine H. Ford and published by . This book was released on 2002-11-01 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report validates the performance and life cycle costs of molecular recognition technology (MRT) for selective heavy metal recovery from industrial process waste streams. MRT selectively removes heavy metal ions using synthetic chemical compounds called macrocyclic ligands. These ligands complex with the targeted heavy metal ions while allowing alkaline earth and alkali metal ions to pass through the MRT system. The captured heavy metal ions can be regenerated in a highly purified concentrated form, which can be recycled back to the industrial process or sold to a metal reclaimer. IBC Technologies, Inc., has patented these macrocyclic ligands as Superligs. MRT can recover in a single process Cu, Cd, Cr (Cr VI or Cr III), Ni, Pb, Zn, and Ag to below regulated discharge limits for industrial wastewater treatment plants. For other applications, MRT can be designed to remove single metal ions such as arsenic (As). This report includes all the data from the operational runs of the pilot scale MRT demonstration at Puget Sound Naval Shipyard's industrial wastewater pretreatment facility (IWPF). At the IWPF, two MRT mixed bed columns were used where Superlig 327 recovered copper, lead, silver, nickel, cadmium and zinc from the influent stream. Superlig 3O7 and Superlig 310 were used to recover chromium (VI) and chromium (III) respectively. The efficiency of MRT system was calculated and cost data presented along with a discussion of regulatory issues.

Download or read book Sustainable Heavy Metal Remediation written by Eldon R. Rene and published by Springer. This book was released on 2017-10-13 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an assortment of case-studies pertaining to the use of sustainable technologies for heavy metal removal and recovery from mining and metallurgical wastes, construction and demolition wastes, spent catalysts and electronic wastes. Wastewaters from diverse industrial and mining activities have caused pollution problems, but these sectors also serve as a hotspot for metal recovery. Several metal removal technologies based on physical, chemical and biological processes have been successfully implemented in full-scale operation, while metal recovery, which is beneficial for economic and environmental reasons, is still limited due to challenges arising from downstream processing. For instance, microbial recovery (bioleaching) of metals from their ores is an established technology with a number of full-scale applications. Bioleaching of electronic wastes to recover metals is also a highly promising technology with low environmental impact and high cost-effectiveness; yet, this technology is still at its infancy. As the individual chapters of this book focuses on the applications and limitations of different technologies, this book will serve as an excellent resource for chemical engineers, environmental engineers, mining engineers, biotechnologists, graduate students and researchers in these areas.

Download or read book Metal Removal and Recovery from Mining Wastewater and E waste Leachate written by Suthee Janyasuthiwong and published by CRC Press. This book was released on 2020-02-18 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal contamination in the environment is a persisting global issue. The metal reservoirs in the earth have declined due to society’s needs and due to uncontrolled mining activities. Therefore, the idea to recover metals from waste streams has emerged. In this thesis, cost competitive technologies such as adsorption using agro-wastes and precipitation using an inverse fluidized bed (IFB) reactor were investigated, with special emphasis on the recovery of base metals. Groundnut shell showed good potential for metal (Cu, Pb and Zn) removal. From artificial neural network modeling, the performance of the sulfate reducing bacteria (SRB) was found to be strongly pH dependent; the removal efficiency of Cu and Zn in the IFB at pH 5.0 was >97%. Electronic waste is a good candidate as secondary metal resource. The recovery of Cu from computer printed circuited boards (PCBs) using biogenic sulfide precipitation was investigated as well. Using this technology, Cu could be recovered at ~0.48 g Cu/g PCBs.
