Disposal of an industrial waste like flyash produced from burning of coals in thermal power stations requires a large land area. The decreasing availability of good construction site has led to the increased use of low lying areas filled up with industrial wastes whose bearing capacity is low. In-situ treatment of such industrial waste fills; in order to improve their bearing capacity with rein...

The utilization of coal as an energy source is still the main choice textile industry in Indonesia. process this left 20% FABA (fly ash-bottom ash) where 80% them were bottom ashes which are considered hazardous and toxic waste. This study aims to obtain technology production for treating ash biomass from urban waste alternative reducing environmental problems (zero waste: material). Biomass Co...

The ferroalloys industry has generated historically substantial solid waste. The accumulated waste causes serious problems to the environment. However, it is possible to transform the solid waste into an environment-friendly resource to serve the human being. Consequently, the construction of plants that are “environment-friendly” and that accommodate “recycling” has become a target of most fer...

the removal ofxylenol orange from aqueous solution onto the coal ash was investigated at room temperature. the results show that the adsorption capacity of xylenol orange increased as the adsorption time increased and then equilibrium established after 30 min adsorption time. the results obtained revealed that the coal ash removed about 80 % of xylenol orange from the aqueous solution within 40...

500 million tons of coal fly ash are produced worldwide every year with only 16% of the total amount utilized. Therefore, potential applications using fly ash have both environmental and industrial interests. Unburned carbon concentration measurements are fundamental to effective fly ash applications. Current on-line measurement accuracies are strongly affected by the mineral content and coal r...

An estimated 229,000 m(3) of coal fly ash remains in the river system after dredging to clean-up the 2008 Tennessee Valley Authority (TVA) spill in Kingston, Tennessee. The ash is heterogeneous with clear, orange and black spheres and non-spherical amorphous particles. Combustion produces iron oxides that allow low field magnetic susceptibility (χ(LF)) and percent frequency dependent susceptibi...

The material recovery methods used by dust-yards in early 19 th century London, England and the conditions that led to their development, success and decline are reported. The overall system developed in response to the market value of constituents of municipal waste, and particularly the high coal ash content of household 'dust.' The emergence of lucrative markets for 'soil' and 'breeze' produ...

The experimental determination of mineral matter in coal is a tedious as well as time consuming process, and requires highly skilled analyst to carry out the chemical analysis of coal and ash. On the other hand, determination of moisture and ash is relatively easy using moisture oven and muffle furnace and can be determined anywhere with little care. Most of the methods reported till date for t...

Abstract--Textile dying industry effluents are highly toxic in nature and it contains a large number of complex metal dyes. Many dyes used in textile industries are stable to light and resistant to aerobic digestion. Thus removal of coloured waste from industrial dye effluent is a most perplexing problem to such industries and the environment. On the other hand fly ash is a major pollutant gene...

The bioremediation of industrial waste water by macroalgae is a sustainable and renewable approach to the treatment of waste water produced by multiple industries. However, few studies have tested the bioremediation of complex multi-element waste streams from coal-fired power stations by live algae. This study compares the ability of three species of green freshwater macroalgae from the genus O...
