When the concentration of hexavalent chromium (Cr( vi )) in environment is greater than a certain limit, it becomes global concern.
In this study, the drying of oyster mushrooms (
Abstract Purifying water for diverse uses is vital, but concerns lie with the sustainability and accessibility of purification materials. As such, this study converted readily available treatment plant sludge (WTPS) into activated adsorbent phosphate removal in wastewater. WTPS was via thermal activation at 300 °C temperature chemical processes 3 M acid concentration, 4 h time, 75 temperature, then characterized using Brunauer-Emmett-Teller (BET), scanning electron microscopy (SEM), Fourier...
Drying of mushroom up to the optimal moisture content is an important preservation technique. This research contains data drying kinetics, sorption isotherm, and evaluation functional groups fresh dried oyster (Pleurotus ostreatus) while in tray dryer using hot air-drying medium. Mushrooms macronutrients that used as supplementary foods make it perishable with short time. Various kinetics models at different temperatures (50, 55, 60, 65, 70, 75 °C) for was studied drying. The parameters...
In this study, CFD simulations that incorporate the inherent coupling between moisture content of mushroom and hot air flow in tray dryer were performed. Conservation principles applied to fundamental quantities mass, momentum, heat. The source terms due evaporation, viscous inertial resistance, continuous evaporative cooling determined through experimental results. Experiments conducted study select drying kinetics model at optimum conditions sorption isotherm 30, 40, 50°C temperatures....
