This book was released on 1999 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mercury-contaminated wastes in many forms are present at various U.S. Department of Energy (DOE) sites. Based on efforts led by the Mixed Waste Focus Area (MWFA) and its Mercury Working Group (HgWG), the inventory of wastes contaminated with 260 ppm mercury and with radionuclides stored at various DOE sites is estimated to be approximately 6,000 m3 (Conley, Morris, Osborne-Lee, and Hulet 1998). At least 26 different DOE sites have this type of mixed low-level waste in their storage facilities. Extraction methods are required to remove mercury from waste containing260 ppm levels, but below 260 ppm Hg contamination levels, the U.S. Environmental Protection Agency (EPA) does not require removal of mercury from the waste. Steps must still be taken, however, to ensure that the final waste form does not leach mercury in excess of the limit for mercury prescribed in the Resource Conservation and Recovery Act (RCRA) when subjected to the Toxicity Characteristic Leaching Procedure (TCLP). At this time, the limit is 0.20mg/L. However, in the year 2000, the more stringent Universal Treatment Standard (UTS) of 0.025 mg/L will be used as the target endpoint. Mercury contamination in the wastes at DOE sites presents a challenge because it exists in various forms, such as soil, sludges, and debris. Stabilization is of interest for radioactively contaminated mercury waste (

This book was released on 2013 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mercury is an extremely toxic pollutant that currently being emitted and distributed globally. Microbes have been used to solve environmental wastewater problems for many years. The objective of the study is to remove mercury from petrochemical wastewater using Pseudomonas putida (P. putida), ATCC 49128 in membrane bioreactor to enhance water quality to meet EQA - Industries Effluent 2011 requirements. The approach of this study is focused on the removal or reduction of mercury concentration including development studies of pure culture of P. putida and growth related parameters involved in designing the membrane bioreactor system. Furthermore, this research also provide an understanding of P. putida behavior in rehydrating freeze-dried growing method, growth parameters and optimum operating condition in membrane bioreactor. A field survey on mercury concentrations at several petroleum based industrial plants in Peninsular Malaysia revealed a maximum reading of 2318 ppb which is higher than the Department of Environmental (DOE), Malaysia requirement for Standard B (50 ppb). Hence, treatment study of P. putida on mercury contaminated wastewater was conducted at mercury concentration in the range of 1000 - 4000 ppb. Optimum operating conditions of 24 hours acclimatization time, 180 rpm of orbital shaker speed, temperature of 37oC, pH 7 and nutrient concentration of 8 g/L were identified for P. putida growth in a shaked flask. The overall percentage of mercury removal for sample with 4000 ppb mercury in bioreactor is 99.60% for the first 6 hours and 99.80% removal after the microfiltration membrane system. Microfiltration membrane enhanced further the treatment of the wastewater by retaining the P.putida from escaping during the release of treated wastewater, reducing the turbidity by 94.2% (5.32 NTU) and concentration of suspended solids up to 60.4%. (0.09 mg/L). It was identified that the mechanism of mercury detoxification in the membrane bioreactor was based on reduction of Hg2+ to non-toxic Hg0 by mercury reductase enzyme produced by P. putida. The findings from this study can be used as references for future application of petroleum based industries wastewater treatment as well as other industries related to mercury contamination in their wastewater treatment plant such as gold mining, chemical industries, agriculture etc.

Book Synopsis An Investigation of Increased Mercury Recovery from Industrial Wastewaters by : Sarah O. Schwab
Download or read book An Investigation of Increased Mercury Recovery from Industrial Wastewaters written by Sarah O. Schwab and published by . This book was released on 2005 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: By examining the current wastewater treatment process of increasing pH to enhance settling of particles via hydroxide precipitation, a mercury recovery system can be developed to get better mercury recovery throughout the system. To improve solids settling, the addition of ferric chloride was examined as a flocculent aid and the addition of sodium sulfide was examined as a sulfide precipitation alternative to hydroxide precipitation. The results obtained from bench-scale testing using the parameters of control, ferric chloride addition, sodium sulfide addition, and the addition of both ferric chloride and sodium sulfide suggest that optimal mercury recovery in the treated sludge and negligible mercury recovery in the treated wastewater is best achieved using the addition of ferric chloride alone. A conceptual design with order of magnitude cost estimate is included for the automatic chemical addition of both sodium hydroxide and ferric chloride.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers comprehensive coverage of the design, analysis, and operational aspects of biomass gasification, the key technology enabling the production of biofuels from all viable sources--some examples being sugar cane and switchgrass. This versatile resource not only explains the basic principles of energy conversion systems, but also provides valuable insight into the design of biomass gasifiers. The author provides many worked out design problems, step-by-step design procedures and real data on commercially operating systems. After fossil fuels, biomass is the most widely used fuel in the world. Biomass resources show a considerable potential in the long term if residues are properly handled and dedicated energy crops are grown. Includes step-by-step design procedures and case studies for Biomass GasificationProvides worked process flow diagrams for gasifier design. Covers integration with other technologies (e.g. gas turbine, engine, fuel cells)
