Environmental and economic assessment of municipal sewage sludge management – a case study in Beijing, China
A case study was conducted in Beijing to identify municipal sewage sludge (SS) management systems appropriate for a sound material-cycle society. The environmental and economic impacts of four realistic SS-handling scenarios were investigated: stabilization by thermal drying, increased inclusion of SS in cement manufacture, and using either dried or carbonized SS as substitute fuel for ...

Concentrations of gaseous trace elements such as mercury in the ambient air of the Netherlands
ABSTRACT Around the world, there is increasing concern about mercury in the environment. Sources of mercury emissions to the air include municipal waste incineration plants, coal-fired power plants and municipal sewage sludge disposal. The emission of mercury from coal-fired power plants in the Netherlands is well documented. However, to assess the environmental consequences of the emissions of ...

Overview of mercury control in coal-fired power plants
During combustion, the mercury (Hg) in coal is volatilized and converted to elemental mercury (Hg0) vapor in the high temperature regions of coal-fired boilers. As the flue gas is cooled, a series of complex reactions begin to convert Hg0 to ionic mercury (Hg2+) compounds and/or Hg compounds (Hgp) that are in a solid-phase at flue gas cleaning temperatures or Hg that is adsorbed onto the surface ...

Study: Coal-Fired Power Plants Are Polluting Groundwater
Environmental groups are pushing for tighter regulation and enforcement of EPA rules A new study shows that of the 265 coal-burning power plants it studied in the United States, 241 have dangerous levels of toxic metals in the groundwater around them, based on Environmental Protection Agency (EPA) standards. The figure, which comes to 91% of the plants, was derived only from plants that must ...

PM10 and PM2.5 - legislation, measurement and control
New standards for PM10 and PM2.5 in ambient air are being formulated in Europe and the USA. There is much controversy over this legislation, not only with respect to the stringent limits proposed, but also due to the many problems associated with ensuring compliance with standards for a pollutant which is so poorly understood. New sampling and analysis techniques are being developed to improve ...

How Low-Temperature Evaporation Treats FGD Wastewater
Veolia Water Technologies’ low-temperature CoLD crystallizer technology can help coal power plants clean and recover water for reuse from the wastewater produced in wet scrubber systems. The innovative solution provides effective wastewater treatment at lower capital and operational expenses than those of conventional thermal zero liquid discharge options. Despite rising ...

Powering China with Sludge and Reclaimed Water
A symbiosis of wastewater and power infrastructure could save billions Coal-fired power plants are responsible for a significant amount of carbon emissions and water consumption. That’s important when half the world’s population may face dwindling water supplies. New research suggests that pairing coal plants with wastewater treatment plants could lessen both problems. A recent ...

INFORSE proposals for EU emissions trading scheme
The first period of the EU-ETS (2005-2007) has shown a number of weaknesses in the system which clearly show the needs for better frameworks for the EU-ETS as part EU climate policies. Some of the main problems of the first period of the EU-ETS were: Large variations in prices of allowances, reducing the incentives for long-term investments to reduce emissions. Much too low prices in the last ...

Simulation of plume dispersion using different stack configurations and meteorological inputs
The application of CALMET/CALPUFF modelling system is well known, and several validation tests were performed until now; however, most of them were based on experiments with a large compilation of surface and aloft meteorological measurements, not always available. Also, the use of an operational large smokestack as tracer source is not so usual. In this work, CALPUFF model is applied to ...

3 Questions: Amanda Giang on controlling Mercury Pollution in India and China
Original story at MIT News MIT graduate student studies how a new U.N. treaty could affect mercury emissions from coal power plants in Asia. The Minamata Convention on Mercury, a global treaty adopted by the United Nations in 2013, aims to reduce worldwide mercury pollution by setting limits on specific pollution sources and prohibiting new mercury mining. Certain aspects of the treaty are ...

Horizontal Plate Clarifiers Treat Power Plant Stormwater - Case Study
Challenge A coal fired power plant needed an upgraded stormwater treatment system to properly deal with high levels of coal ash (from coal pile run-off), solids, and oil prior to discharge. The plant had previously collected run-off and stormwater into in-ground basins that were then pumped through a coalescing (CPI) oil/water separator. The ash and other solids in the stream plugged the ...

Legal lookout: EPA responds to coal ash release
Once again, it took a major catastrophe to wake up industry and regulators to a problem that should have been addressed long ago. Dec. 22, 2008, was a nightmare for federal and state regulators, electrical utilities, and most particularly the residents of Kingston, Tenn. On this day, approximately 5.4 million cubic yards (or 1.1 billion gallons) of coal ash from the Tennessee Valley Authority ...

Simultaneous removal of Ni(II) and fluoride from a real flue gas desulfurization wastewater by electrocoagulation using Fe/C/Al electrode
Large amounts of anions and heavy metals coexist in flue gas desulfurization (FGD) wastewater originating from coal-fired power plants, which cause serious environmental pollution. Electrocoagulation (EC) with Fe/C/Al hybrid electrodes was investigated for the separation of fluoride and nickel ions from a FGD wastewater. The study mainly focused on the technology parameters including anode ...
