Simultaneous nitrification-denitrification in a sequencing batch reactor equipped with fixed Kaldnes carriers

Simultaneous nitrification-denitrification in a sequencing batch reactor equipped with fixed Kaldnes carriers

The main aim of this study was to evaluate the performance of a modified sequencing batch reactor (MSBR) using fixed Kaldnes carriers fed with acclimated sludge for ammonium removal via simultaneous nitrification-denitrification (SND) in synthetic wastewater.

Removal of hexavalent chromium from aqueous solution using canola biomass: Isotherms and kinetics studies

Removal of hexavalent chromium from aqueous solution using canola biomass: Isotherms and kinetics studies

The removing of hexavalent chromium from wastewater or decreasing its chromium (VI) content up to the permitted levels is important due to its non-biodegradation, bioaccumulation, and cancer-causing and toxic effects. In the present study, biosorption of Cr (VI) from aqueous solutions using canola was investigated.

Chemical composition of indoor ash residues

Chemical composition of indoor ash residues

The ash content formed after burning of materials in indoor may be harmful to environment on dumping due to high ionic and metallic concentration. Therefore, the chemical composition of various indoor ash residues derived from burning of the biomass (BM), coal (C), cow dung (CD), incense (IS) and mosquito coil (MC) materials is described in this study.
