  • Laboratory Filter Paper Suction Measurements

    Results of filter paper measurements for both matric and total suction values are reported for a sand, silt, and clay. Calibration curves for the matric and total suction are given for the filter paper used in this study, and comparisons with the results of several other researchers are made. For low suction values, the matric suction is more easily measured than the total suction using the ...

  • Suction-Moisture Content Calibration of Filter Papers from Different Boxes

    The filter paper method is probably the simplest of the methods available for estimating the suction of a clay soil. The method measures soil suction indirectly by simply measuring the moisture content of a filter paper having been brought to the same suction as the soil. Calibration of representative specimens of the filter paper over a range of known suctions defines the suction-moisture ...

  • Case study: Pulp & paper plant

    OverviewEuropaper produces tissues paper for Industrie Cartarie Tronchetti, which has its own branch (Foxy). Changes in the paper production were followed by an increase of the BOD load in the wastewater. Therefore the existing water treatment plant had to be upgraded. RequirementsAn increased BOD load in the wastewater, caused by a conversion of production, required an ...

  • Case study: Pulp & paper industry

    OverviewThe paper mill at Valdivia produces card board from chemical and mechanical pulp. With the installation of an additional paper machine, the wastewater flow increased from 4,000 m3/d to 8,500 m3/d and therefore an extension of the existing wastewater treatment plant was required. RequirementSo far, the existing effluent treatment plant consisted of a primary ...

  • Monitoring Leaks from Heat Exchanger - Paper Plant

    The Situation A Paper plant in the Eastern US uses 500 GPM filtered pond water for cooling lubricating oil in their paper line.  The now warmer water is sewer to an on-site pond.  Because the water is used to cool lubricating oil, the plant could not reuse the water in their pulping process for fears of possible oil contamination of the paper pulp.  The plant needed to be ...

  • Controlling scale deposits in the pulp & paper industry

    The pulp and paper industry is one of the heaviest users of water within the North American industrial economy, requiring on average 54 cubic meters of water per metric ton of finished product.  As water is used in nearly every part of the manufacturing process, accumulation of scale is a phenomenon that can occur in all pulp and paper making processes. This occurs even with the purest water ...

  • Paper fibers as a carbon source for the de novo formation of polychlorinated dioxins and furans

    The formation of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/Fs) from carbon that was produced by the pyrolysis of paper fibers and from wood charcoal was investigated experimentally. Fibers obtained from filter paper were pyrolyzed at 300° and 800°C to produce low- and high-temperature carbon samples. The two types of carbon and wood charcoal were mixed with silica ...
