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 Unit Operations in Environmental Engineering written by Robert Noyes and published by William Andrew. This book was released on 1994-12-31 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the practical aspects of environmental technology organized into eight chapters relating to unit operations as follows: 1. Biological Technology2. Chemical Technology3. Containment and Barrier Technology4. Immobilization Technology5. Membrane Technology6. Physical Technology7. Radiation and Electrical Technology8. Thermal Destruction TechnologyTraditional technologies have been included, as well as those that can be considered innovative and emerging. The traditional approaches have been the most successful, as contractors are careful about bidding on some of the newer technologies. However, as regulatory requirements increase, markets will open for the innovative and emerging processes. There will be increasing pressure to break down complex waste streams, with each subsequent stream demanding separate treatment. In addition, a number of technologies have been developed by combining processes directly, or in a treatment train, and these developments are expected to assume increasing importance. However, such concerns as uncertainties due to liability, regulatory approval, price competition, and client approval have limited the application of some of these newer technologies.

This book was released on 2005-03-11 with total page 731 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past 30 years have seen the emergence of a growing desire worldwide to take positive actions to restore and protect the environment from the degrading effects of all forms of pollution: air, noise, solid waste, and water. Because pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unrealistic demand for zero waste. However, as long as waste exists, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been identified: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? The principal intention of the Handbook of Environmental Engineering series is to help readers formulate answers to the last two questions. The traditional approach of applying tried-and-true solutions to specific pollution pr- lems has been a major contributing factor to the success of environmental engineering, and has accounted in large measure for the establishment of a “methodology of pollution c- trol. ” However, realization of the ever-increasing complexity and interrelated nature of current environmental problems makes it imperative that intelligent planning of pollution abatement systems be undertaken.

Download or read book Chemical Pretreatment of Nuclear Waste for Disposal written by E.P. Horwitz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical pretreatment of nuclear wastes refers to the sequence of separations processes used to partition such wastes into a small volume of high-level waste for deep geologic disposal and a larger volume of low-level waste for disposal in a near-surface facility. Pretreatment of nuclear wastes now stored at several U. S. Department of Energy sites ranges from simple solid-liquid separations to more complex chemical steps, such as dissolution of sludges and removal of selected radionuclides, e. g. , 90Sr, 99Tc, 137CS, and TRU (transuranium) elements. The driving force for development of chemical pretreatment processes for nuclear wastes is the economic advantage of waste minimization as reflected in lower costs for near-surface disposal compared to the high cost of disposing of wastes in a deep geologic repository. This latter theme is expertly and authoritatively discussed in the introductory paper by J. and L. Bell. Seven papers in this volume describe several separations processes developed or being developed to pretreat the large volume of nuclear wastes stored at the US DOE Hanford and Savannah River sites. These papers include descriptions of the type and amount of important nuclear wastes stored at the Hanford and Savannah River sites as well as presently envisioned strategies for their treatment and final disposal. A paper by Strachan et al. discusses chemical and radiolytic mechanisms for the formation and release of potentially explosive hydrogen gas in Tank 241-SY-101 at the Hanford site.

Book excerpt: Municipal and industrial wastewaters contain a wide spectrum of pollutants. Their effective removal presents a challenge for water treatment technology. Biosorption of nutrients and pollutants has been used in sewage treatment since the discovery of the activated sludge process. It is a passive uptake process by which pollutants are adsorbed on the surface of cell walls and/or dissolved in structures of microorganism cells that are present in sludge. Sorbed pollutants remain in the sludge and can be potentially released back into the environment depending on their condition and the reversibility of the pollutant-sludge interaction. An overview of typical biosorption applications for the removal of nutrients, organic pollutants, and metals in wastewater treatment is provided in different areas of their use for the protection of aquatic ecosystems and human health. This book will be of interest to operators of wastewater treatment plants and sludge treatment and disposal facilities as well as to researchers and university students in the field of environmental engineering.
