Abstract Drinking water quality of surface and underground within 1.34 km from a waste landfill site in Kumasi, Ghana was investigated. Physico‐chemical properties heavy metal concentrations were analysed to determine pollution indices. It found that turbidity 83% hand dug wells, 50% the streams 33% boreholes higher than World Health Organisation (WHO) standards for drinking water. Water index (WQI) showed 25% sources are excellent quality, while 50%, 15% 5% good poor very unsuitable...
Adsorption of methylene blue (MB) dye from an aqueous solution onto hydrochars produced brown seaweed (Fucus Serratus) (FS-HC), coconut shell (CS-HC), and oak wood (Oak-HC) at different temperatures (200–250 °C) was investigated in a batch system. Response surface modelling (RSM) used to investigate the effect initial MB concentration (50–300 mg/L), contact time (0–240 min), pH (2–12) on adsorption process. RSM also model optimise these parameters for efficient adsorption. Kinetic isotherms...
Abstract The present study addresses the production of hydrochars from brown seaweed ( Fucus serratus ) (FS-HCs), coconut shell (CS-HCs), and oak (Oak-HCs) as potential adsorbents using hydrothermal carbonisation (HTC). effect HTC processing temperature on physicochemical adsorbent characteristics is investigated at different temperatures (200, 220, 250 °C) a batch reactor. Increasing causes formation many spheres in CS-HCs Oak-HCs, increasing their porosity, except FS-HCs. surface area...
<abstract> <p>Biofuel and bioenergy production from diverse biomass sources using thermochemical technologies over the last decades has been investigated. The conversion pathways comprise dry processes (i.e., torrefaction, combustion, gasification, pyrolysis), wet liquefaction, supercritical water hydrothermal carbonisation). It found that can convert feedstocks to produce such as direct heat energy, well solid, liquid gaseous biofuels for instance biochar, bio-oil syngas....
Pharmaceutical pollutants in wastewater can be effectively degraded by heterogeneous photocatalytic processes (HPP); under light irradiation, these methods use semiconductor photocatalysts to produce reactive oxygen species (ROS), which oxidize and mineralize organic (OPs) into innocuous byproducts. Reactant transport the photocatalyst surface, reactant adsorption, charge carrier formation separation, redox reactions, product desorption are all part of mechanisms. This review article...
Abstract Surface structure and chemical properties of adsorbents are important factors required to understand the mechanism adsorption. The purpose this study was produce hydrochars from biomass using hydrothermal carbonisation (HTC) analyse their sorption capacities. used in were coco-peat (CP), coconut shell (CS), eggshell (ES), rice husk (RH) lemon peel (LP). operating conditions for HTC 200 °C 20 h residence time. characterisation methods consisted Scanning Electron Microscopy (SEM),...
The hydrothermal carbonisation (HTC) conversion of wet wastes, such as sewage sludge, generates a carbon-rich material (called 'hydrochar'), and an aqueous fraction with small release gas.The liquid is high in soluble chemical oxygen demand, from 10 to 50 g/L, could not be discharged the natural environment without treatment.This study investigates anaerobic digestibility this HTC stream different temperatures retention times (140°C-200°C for 30-240 min).It focused on biogas production order...
The effect of reaction temperature and time on the filterability slurries primary sewage sludge (PSS) synthetic faeces (SF) following hydrothermal carbonization (HTC) was investigated optimized using response surface methodology (RSM). Filterability shown to improve as treatment at which solids were carbonized increased. best filtration results achieved highest (200°C) longest (240 min) employed here. specific cake resistance found vary between 5.43 × 10 12 2.05 m kg −1 for cold PSS, 1.11...
The effects of enzyme action and heat pretreatment on oil extraction yield from sunflower kernels were analysed using hexane with Soxhlet, aqueous incubator shaker. Ground raw treated kernels, each without Viscozyme treatment used. Microscopic images the taken to analyse visible cotyledon cell structure kernels. Heat pretreated before both processes produced enhanced yields than control, steam explosion most efficient. In extraction, applying a combination treatments gave maximum extractable...
