Journal ArticleDOI
Nitrogen removal from synthetic wastewater by simultaneous nitrification and denitrification (SND) via nitrite in an intermittently-aerated reactor
TL;DR: In this article, an intermittently aerated and decanted single-reactor process was proposed and some key control parameters investigated for nitrogen removal from wastewater by simultaneous nitrification and denitrification via nitrite.
Journal ArticleDOI
Fabrication of granular activated carbons derived from spent coffee grounds by entrapment in calcium alginate beads for adsorption of acid orange 7 and methylene blue.
TL;DR: The equilibrium isotherm and isosteric heat of adsorption indicate that SCG-GAC possesses an energetically heterogeneous surface and operates via endothermic process in nature.
Journal ArticleDOI
Characteristics of biochar derived from marine macroalgae and fabrication of granular biochar by entrapment in calcium-alginate beads for phosphate removal from aqueous solution.
TL;DR: Granular biochar, Laminaria japonica-derived biochar (LB)-calcium alginate beads (LB-CAB), was successfully prepared by dropping a mixture of powder biochar and alginates into a calcium chloride solution for phosphate adsorption, showing the best performance among different marine macroalgae derived biochars.
Journal ArticleDOI
Kinetic study on phosphate removal from aqueous solution by biochar derived from peanut shell as renewable adsorptive media
TL;DR: In this article, various types of biochar derived from oak wood, bamboo wood, maize residue, soybean stover, and peanut shell were tested for evaluation of phosphate removal.
Journal ArticleDOI
Adsorption of phosphate from aqueous solution using electrochemically modified biochar calcium-alginate beads: batch and fixed-bed column performance.
TL;DR: Experiments revealed that the phosphate adsorption behavior of EMB-CABs and its structural characteristics were highly dependent on pH condition, and the Yoon-Nelson model showed better agreement with the breakthrough curves than other models.
