Lime mud from paper-making process addition to food waste synergistically enhances hydrogen fermentation performance

Recycling of lime mud and fly ash for fabrication of anorthite ceramic at low sintering temperature

“…The formations of gehlenite and wollastonite were due to the increase of calcium, as shown in Eq. (5). Moreover, with the increase in lime mud content, the intensity of anorthite is gradually decreased while the intensities of gehlenite and wollastonite are rapidly increased:…”

“…Cr, Mn and Fe) [5][6][7][8][9], lime mud is classified as toxic industrial waste. A proper treatment is required for lime mud.…”

Lime mud from papermaking process as a potential ameliorant for pollutants at ambient conditions: a review

“…Mg, K, Na, Cr, Mn, and Fe (He et al, 2009;Martins et al, 2007;P erez-L opez et al, 2010;P€ oyki€ o et al, 2006;Sthiannopkao and Sreesai, 2009;Zhang et al, 2013). It has a pH range of 9.7e13.5 (Catalan and Kumari, 2005;He et al, 2009).…”

“…Ca, Si, Mg, Al and Fe) (Wang et al, 2008;Zhang et al, 2013). Moreover, the activated LMP (treated at 700 C) contains a certain amount of metal oxides (CaO, Fe 2 O 3 , Al 2 O 3 and MgO) that favor removal of phosphate.…”

Preparation and characterization of ceramsite from lime mud and coal fly ash

“…Due to high alkalinity (pH 9.7-13.5) and the existence of alkali metal ions (e.g. Cr, Mn and Fe) [2][3][4][5][6][7], lime mud is classified as toxic industrial waste. It has been estimated that about 0.5 tons of lime mud can be produced by 1 ton of pulp [8].…”
