  • An analysis of extinction coefficients of particles and water moisture in the stack after flue gas desulfurization at a coal-fired power plant

    Two important factors that affect in-stack opacity—light extinction by emitted particles and that by water moisture after a flue gas desulfurization (FGD) unit—are investigated. The mass light extinction coefficients for particles and water moisture, kp and kw, respectively, were determined using the Lambert-Beer law of opacity with a nonlinear least-squares regression method. The ...

  • Strong selection pressures impact the capacity of flocculating activated sludge bacteria to granulate

    The capacity of activated sludge (AS) microbial populations to form dense granules offers the potential to establish efficiently settleable biomass. This has the potential to circumvent problems around ineffective solids–liquid separation and sensitivity to variable chemical oxygen demand (COD) loads. Although a number of studies have evaluated aerobic laboratory granulation reactors as ...

  • A laboratory-scale comparison of compost and sand—compost—perlite as methane-oxidizing biofilter media

    Municipal solid waste landfills produce methane, a potent greenhouse gas. A treatment approach is to passively vent landfill gas through a methane-oxidizing biofilter medium, a porous substrate that facilitates the growth of methanotrophic bacteria. Two substrates, compost and a sand—compost—perlite (SCP) mixture, were evaluated in a laboratory-scale experiment for their suitability as biofilter ...

  • Preferences and requirements for batch mixers used in the food industry

    In the food industry many end products are mixtures of solid substances. Examples of such products are dessert mixtures, sugar blends, instant drinks, dried soups and sauces, dietetic foods and spice mixtures. The great variety of constituents, such as milk powder, cream powder, sugar, cocoa, flour, vegetables, fungi, spices, fats (liquid and solid), places great demands on the batch ...

  • Membrane processing for water treatment in the semiconductor industry

    It is the aim of high-purity water production to either fully eliminate organic and ¡florganic compounds, particles, and microorganisms from the water or to reduce their concentrations to values below the detection limits of the most advanced analysis methods. Currently, this problem is solved by means of a multi-stage process chain, in which membrane technology ...


  • Closures of mine a new challenge for Romania

    AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country. In time the economic content of metals diminuend, and the ore mines become non profitable. Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...
