This paper presents results of investigation of scaling of calcium sulfate (CaSO4) on metallic pipes. In this study, the optimizing variables; namely temperature (50-600C), concentration of Ca2+ (2000-3000 ppm), citric acid concentration (10-20 ppm) were set-up to provide the optimum yield of the mass scales. The mineral scale detected using XRD is mainly gypsum, and the scale has a plate like ...
Dairy products provide abundant, accessible calcium for humans, while some calcium sulfate-rich mineral waters could provide appreciable amounts of calcium. But there is little evidence that this calcium is as available as milk calcium for making bone. The availability of calcium was studied by monitoring bone parameters in 2-month-old pigs fed restricted amounts of calcium (70% RDA) for 2.5 mo...
Landfill leachate membrane concentrate (LLMC) poses risks to the environment and is commonly treated by evaporation. As main component of dissolved organic matter in LLMC, fulvic acid (FA) was selected as a representative investigate its effect on evaporation removal efficiency pretreatment this study. According water quality indexes three-dimensional fluorescence spectra LLMC samples collected...
