Evaluating Algibon adsorbent and adsorption kinetics for launderette water treatment: towards sustainable water management

Abstract

Grey water from commercial laundry facility was used for treatment to substitute the conventional water sources. Algibon, A800 derived from mesoporous alginic acid and Starbon S300, carbonaceous mesoporous polysaccharide-derived materials, silica gel (SG) and activated carbon (AC) were used for the treatment of wastewater. The optimum adsorbent dosing and pH value for each adsorption system are defined. The adsorption efficiency are in the order of A800 > SG > AC > S300 and the removal rate reached to 91% when A800 was used. Furthermore, the reaction followed the second-order kinetic model and the rate constant is high when A800 adsorbent is applied.

Removal of the commercial reactive dye Procion Blue MX-7RX from real textile wastewater using the synthesized Fe2O3 nanoparticles at different particle sizes as a source of Fenton's reagent

“…Thus, the result is a new kind of pollution that requires secondary treatment. 14,15 The development of new advanced techniques, called advanced oxidation processes (AOPs), is growing in importance since they are environmentally-friendly processes that produce harmless end products, CO 2 and H 2 O. 8,[16][17][18] AOPs are based on the generation of in situ cOH radicals involving several systems such as chemical oxidation, electro-catalytic oxidation, photochemical reaction and Fenton's reagent.…”

Engineered nanostructured ZnO for water remediation: operational parameters effect, Box–Behnken design optimization and kinetic determinations

“…Conventionally, various techniques were applied for wastewater treatment such as coagulation, reverse osmosis, biological treatment techniques and adsorption methods (Beydoun et al 1999;Ashour et al 2014;Tony et al 2018). However, those methods are not widely recommended as they are expensive, transferring the pollutants phase, or they are not effective with high organic loads (Rahman et al 2009;Tony and Mansour 2019).…”

Sustainable waste management and recycling of Zn–Al layered double hydroxide after adsorption of levofloxacin as a safe anti-inflammatory nanomaterial

“…25 Also, activated carbon, silica gel and LDHs have been used for the treatment of wastewater. 26 Moreover, the adsorption of levo onto the surface of Fe 3 O 4 and Fe 3 O 4 @SiO 2 nanomaterials has been studied and the maximum adsorption capacity of levo on Fe 3 O 4 nanoparticles was estimated to be in the range of 6.094 to 6.848 mg g À1 . Yu et al 27 applied agricultural waste corn bracts (CBs) modied by zirconium cations as promising adsorbent materials for the removal of levo.…”
