the purpose of this study is the utilization of furfural residue for heating energy and activated carbon production. to evaluate the energy production of the residue, bulk density, melting point, and heating value were measured. furthermore, moisture, ash, volatile compounds, fixed carbon, lignin, and elements were determined. ash and volatile content average were measured at 15.4% and 68.9%, r...

Background Aerobic granular sludge has become an attractive alternative to the conventional activated sludge due to its high settling velocity, compact structure, and higher tolerance to toxic substances and adverse conditions. Aerobic granular sludge process has been studied intensively in the treatment of municipal and industrial wastewater. However, information on leachate treatment using ae...

For predicting the adsorption performance of filters, rate parameters, including mass transfer capacity coefficient and equilibrium concentration are required. Estimating these parameters involve a series experiments on concentrations amounts adsorbent, which is expensive requires sufficient time for tests. This study aims to estimate more efficiently using computational fluid dynamics (CFD); m...

One of the famous dyes is methylene blue (MB) which is a symbol of hazardous dyes. In this research, methylene blue was adsorbed using the blends of saffron petals with activated carbon. Five independent variables involving pH (2-13), contact time (5-270 min), saffron petals powder dosage (0.1-10 g/l), initial concentration of methylene blue solution (20-300 ppm) and activated carbon dosage (0....

The nanocarbon-based mixture was shown to be an effective adsorbent for removing dyes and heavy metals from wastewater via adsorption. goal of this research prepare investigate the properties a bio-carbon made Dabai (Canarium odontophyllum) nutshell with addition titanium dioxide (TiO2) montmorillonite (MMT) clay. Fourier transform infrared (FTIR) spectroscopy used determine functional groups r...
