Book Synopsis Recycling, Reuse, and Resource Recovery from Fly Ash by : Jingjing Ling
Download or read book Recycling, Reuse, and Resource Recovery from Fly Ash written by Jingjing Ling and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fly ash (FA) is a particulate residue from power plant boiler by burning oil or biomass. In this study fly ash was used to (a) remove total organic carbon (TOC) from intake water; (b) clean up an offshore oil spill; and (c) compost and stabilize municipal sludge. Firstly, oil fly ash (OFA) from oil-fired power plants was characterized, cleaned, homogenized, and activated to prepare activated carbon (AC). Since the drinking water from many small communities in the province of Newfoundland and Labrador has high levels of dissolved natural organic matter (NOM) in their water intake sources, causing the formation of disinfection by-products (DBPs) which are harmful to health, the AC from OFA was used to reduce DBP formation in the drinking water by removing NOM before chlorination. The NOM is typically measured as TOC. The results showed that the AC from fine and coarse OFA could remove 90% and 60% of the TOC from the source water, respectively. Secondly, acid treated OFA and activated carbon obtained from OFA (AC-OFA) were used to remove oil from the surface of water, by agglomerating oil droplets to form larger particles which could attach with the OFA. Due to the nature of hydrophobic, both OFA samples can keep floating on the water surface without sedimentation. The oil adsorption capacity of OFA could go up to 1.08.

Download or read book Fly Ash written by Peter H. Telone and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fly ash is one of the residues generated in the combustion of coal. Fly ash is generally captured from the chimneys of coal-fired power plants, and is one of two types of ash that jointly are known as coal ash; the other, bottom ash, is removed from the bottom of coal furnaces. Depending upon the source and makeup of the coal being burned, the components of fly ash vary considerably, but all fly ash includes substantial amounts of silicon dioxide (SiO2) (both amorphous and crystalline) and calcium oxide (CaO). Toxic constituents include arsenic, beryllium, boron, cadmium, chromium, chromium VI, cobalt, lead, manganese, mercury, molybdenum, selenium, strontium, thallium, and vanadium, along with dioxins and PAH compounds. In the past, fly ash was generally released into the atmosphere, but pollution control equipment mandated in recent decades now require that it be captured prior to release. In the US, fly ash is generally stored at coal power plants or placed in landfills. About 43 percent is recycled, often used to supplement Portland cement in concrete production. It is increasingly finding use in the synthesis of geopolymers and zeolites.

Book excerpt: Industrialization is the process of social and economic change that transforms a human group from a pre-industrial society into an industrial one. It is a part of a wider modernization process, where social change and economic development are closely related with technological innovation, particularly with the development of large scale energy and metallurgy production. Industrial pollution hurts the environment in a range of ways, and it has a negative impact on human lives and health. Pollutants can kill animals and plants, imbalance ecosystems, degrade air quality radically, damage buildings, and generally degrade quality of life. India is a home to many industries. The sectors include Iron and Steel, Pulp and Paper, Food Processing, Chemicals, Aluminium Industry, Cement, Pharmaceuticals, Machine tools, Surface finishing Industries etc. However, the industrial growth happening at a breakneck speed has resulted in a significant contribution to the toxicity in the environment. Therefore industrial activities should comply with regulatory norms for prevention and control of pollution. There have been many guidelines for the industries and the pollution caused by them. The setup and implementation of these guidelines is a joint responsibility of the central and state governments along with the Central Pollution Control Board to curb such emissions. At present, the control of pollution from industrial installations remains a key issue in India. As urbanisation expands and cities grow the need to deal with the environmental impact becomes even more important to ensure sustainable development. This also entails handling increasing volumes of waste water. Efficient wastewater management exploiting the capacity optimally requires a thorough understanding of the pollutions sources origin and substance. Hence pollution sources must be mapped and identified. This book is designed to assist in the identification and implementation of a cost effective program for industrial pollution monitoring, control, and abatement within the context of institutional and financial constraints present in India. The book is a complete guide on industrial pollution control in important industries like Iron and Steel, Pulp and Paper, Food processing, Chemicals, Aluminium industry, Cement, Pharmaceuticals, Paint industry and many more.

Download or read book Coal Fly Ash written by Miriam Gray and published by Nova Science Publishers. This book was released on 2018-11-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Due to rising energy demand, the amount of coal utilization is escalating at a fast rate, leading to a rise in ash generation. Coal Fly Ash: Properties, Applications and Performance begins by presenting a study wherein the physiochemical properties of coal ash were analysed and based on that, their potential for reuse was identified. Next, the synergy between Portland cement and coal fly ash was investigated. Raw materials were characterized in terms of chemical and mineralogical composition and physical properties. Mortars were manufactured and the effect of the addition of different ratios of coal fly ash (0-80 wt %) as a partial substitute of Portland cement was studied. Following this, an investigation was carried out to explore the behaviour of coal ash with hydrated lime as mineral filler in hot mix asphalt, in an attempt to determine a sustainable solution for the management of coal ash in Mauritius. The closing chapter describes the synthesis process used to obtain zeolite Na-A from coal fly ash via fusion with NaOH followed by hydrothermal reaction. Coal fly ash is a low cost source of both silica and alumina. The molar ratio of SiO2/Al2O3 for zeolite 4A formation was achieved through the addition of sodium aluminate solution/aluminum waste as aluminum sources"--
