In the present study, semi – batch experiments were conducted to investigate the efficiency of ozone microbubbles (OMBs) in the treatment of aqueous dye solutions methylene orange under different reaction conditions such as effect of initial solution pH , ozone generation rate and initial MO-concentration. The results showed that the removal of MO by OMBs were very high at the acidic and alkaline media and upon increasing the generation rate of ozone from 0.498 to 0.83 mg/s, the removal efficiency dramatically increased from 75to 100% within 15 min. The rate of oxidation reaction followed a pseudo first- order kinetic model. The results demonstrated that OMBs is efficient in terms of the decline of methylene orange concentration and its total mineralization.

“…The previously reported research with biomass‐derived biochar for the adsorption of MO was very efficient. Some of the reported adsorbents for MO adsorption are pulp sludge (Chaukura et al, 2017), chicken manure (Yu et al, 2018), sawdust biochar (Abdulrahman Hanoon & Ahmed, 2019), pomelo peel waste (Zhang et al, 2020), with maximum adsorption capacities of 16.05, 39.47, 136.67, and 163.105 mg/g, respectively. In this study, the synthesized activated biochar at 500°C showed the efficiency of 99.3% removal and 175 mg/g capacity, which is superior than many graphitic sorbents (Chowdhury et al, 2020).…”

Biochar is a promising engineering material to sequestrate organic pollutants from wastewater. In the current study, several surface-modified Moringa (M.) oleifera leaf biochars were prepared and utilized for the sorption of methyl orange (MO) dye from an aqueous solution. Raw biochar was produced by the carbonization of M. oleifera leaves at 350°C in a muffle furnace for 2 h. The surface-modified M. oleifera biochars were prepared at 400°C, 500°C, and 600°C using phosphoric acid (H 3 PO 4 ) at different combinations to improve the biochar pore structure, surface functional groups, and biochar stability. The highest surface area (267.15 ± 42.40 m 2 /g) of the modified biochar was achieved at 500°C with H 3 PO 4 to raw biochar ratio of 1.5. Surface morphological results revealed the formation of pores, troughs, and channels with the increasing activation temperature. The carbon (C) content (wt%) was maximum (79.61%) for activated biochar at 500°C. The presence of enhanced functional groups, e.g., hydroxyl, aliphatic carbon-hydrogen, carbonyl, ester, and phenol structures in surface-modified biochars was observed from FT-IR results. The Langmuir isotherm model was fitted to better describe the adsorption phenomenon for both surface-modified biochars and raw biochar compared to the Freundlich isotherm model. The highest adsorption capacity was

“…[16][17][18][19]. Previous studies showed that AC can be prepared from agro wastes such as date stones [15,18,[20][21][22], coconut shell [15], scrape tires [18], chitin [23], sawdust [24], seaweed [25]. In terms of OS, previous researchers mostly focused on its carbonization and a composite of sewage sludge along with the production of porous carbon using it with physical or chemical activation [26].…”

Annually, a high amount of hazardous oily sludge (OS) is produced by North Refineries Company (NRC) Baiji. This work aims to study the specifications of oily sludge in crude oil storage tanks and to convert it into activated carbon (AC) by pyrolysis using KOH activated agent. The physical properties of OS have been measured and analyzed. The AC is produced by carbonizing oily sludge to char under N2 flow using KOH at an impregnation ratio of 2:1 KOH/char. The pore structure, morphology of the surface, and surface chemistry of the AC produced were characterized using Brunauer-Emmet-Teller (BET), Fourier Electron Scanning Electron Microscopy (FESEM), and Fourier-Transform Infrared Spectroscopy (FTIR). The result shows the surface area of the produced AC was 350 m2/g with a mesoporous structure. Based on the findings, the obtained surface area of the AC indicates the oily sludge was a light precursor, which is helpful in producing gas and liquid fuels rather than solid fuel.
