Book excerpt: Rapid industrialization is one of the major threats to water pollution worldwide, as discharge effluents contain large amounts of toxic metal ions. Heavy metals are highly toxic to the ecosystem and human even at very low concentrations. We focused on easily available, green and eco-friendly with low operational cost materials to remove heavy metals from industrial wastewater. Chitosan is considered an alternative and sustainable adsorbent due to its highly efficient adsorption capacities for heavy metals. In this particular study, chitosan was successfully modified by using diatomaceous earth and then fabricated as spherical beads using the drop-wise method. Pristine chitosan (CS) beads and chitosan coated diatomaceous earth (CSDE) beads were used to remove zinc, chromium, lead, and nickel ions from aqueous solutions in batch and continuous adsorption processes. The prepared adsorbents were characterized by using scanning electron microscopy (SEM), Brunauer−Emmett−Teller (BET), Fourier-transform infrared spectroscopy (FTIR), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and zeta potential. The results showed that the prepared adsorbents were porous in nature and the total surface area were increased from 1.9 m2/g for pristine chitosan to 14.4 m2/g for chitosan coated diatomaceous earth. The performance of prepared adsorbents was investigated at different temperatures, initial pH of the solution, contact times, initial metal concentrations. The pseudo-second-order kinetic model is more likely to predict the kinetic behavior of the metal ions adsorption process for the whole used contact time range, and the adsorption isotherm data of CS and CSDE beads were well fitted to Langmuir model. The maximal adsorption capacities of prepared CSDE beads were found to be pH dependent as follows: - Zinc ion - 127.4 mg/g at initial Zn(II) concentration 500 mg/L and pH 6. - Chromium ion - 84.23 mg/g at initial Cr(VI) concentration 1000 mg/L and pH 3. - Lead ion - 175.22 mg/g at initial Pb(II) concentration 400 mg/L and pH 7. - Nickel ion - 149.64 mg/g at initial Ni(II) concentration 400 mg/L and pH 6. Successful desorption and regeneration of prepared adsorbents were achieved (with common chemicals) and possessed excellent reusability (up to 10 cycles without a significant loss in adsorption capacity). The common anions and cations coexisting ions have insignificant impact on the removal capacity of prepared adsorbents. Overall, these results suggest that the environmentally friendly materials might be recognized as effective adsorbent and sustainable means for the separation of heavy metals from wastewater streams. That will lead to a new solution to water pollution required in the modern industrial society.
Book Synopsis Physicochemical Treatment Processes by : Lawrence K. Wang
Download or read book Physicochemical Treatment Processes written by Lawrence K. Wang and published by Springer Science & Business Media. 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 Biosorption written by Jan Derco and published by BoD – Books on Demand. This book was released on 2018-07-18 with total page 159 pages. Available in PDF, EPUB and Kindle. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Fundamental societal changes resulted from the necessity of people to get organized in mining, transporting, processing, and circulating the heavy metals and their follow-up products, which in consequence resulted in a differentiation of society into diversified professions and even societal strata. Heavy metals are highly demanded technological materials, which drive welfare and progress of the human society, and often play essential metabolic roles. However, their eminent toxicity challenges the field of chemistry, physics, engineering, cleaner production, electronics, metabolomics, botany, biotechnology, and microbiology in an interdisciplinary and cross-sectorial manner. Today, all these scientific disciplines are called to dedicate their efforts in a synergistic way to avoid exposure of heavy metals into the eco- and biosphere, to reliably monitor and quantify heavy metal contamination, and to foster the development of novel strategies to remediate damage caused by heavy metals.
