CFD Modeling of an activated sludge bubble column
(2017)The bubble columns are widely used in different industries such as wastewater treatment, chemical, petrochemical, and biochemical. The current design of the bubble columns including but not limited to the geometry and ... -
The effect of vertical internals on the hydrodynamics and phase dispersions in bubble columns: CFD simulation and population balance model
(2018)Vertical internals are widely installed in the bubble columns as heat exchangers or illuminating tubes. This research aims to investigate the effect of dense vertical internals (rods) on the performance of bubble columns. ... -
Experimental study on mixing of activated sludge with or without air in a mixing tank through electrical resistance tomography (ERT) and response surface methodology
(2017)In such industrial processes as oxidation, hydrogenation, and biological fermentation gas and liquid are contacted and mixed to reach steady condition. The unit operations applied for gas/liquid processes include but are ... -
Investigation on liquid-liquid dispersion in stirred tanks through experimental approach and computational fluid dynamic (CFD)
(2019)Stirred tanks have a vital role in chemical engineering industries. Among the various applications of stirred tanks, mixing of two immiscible liquid phases is of interest in chemical processes. Mixing of two immiscible ... -
Lignin acrylic acid polymer as an emulsifier for oil-water emulsions
(2022)Oil-water emulsions are applied in various fields such as food, cosmetics, pharmaceuticals, petrochemicals, and agricultural products. Currently, synthetic-based emulsifiers are extensively used in oil-water emulsions, ... -
Lignin-based hydrogels
(2017)Currently, limited information is available on lignin-based hydrogels, but its potential in commercial applications presents a promising avenue for the utilization of lignocellulosic materials. Recent studies have employed ... -
Synthesized emulsifiers from kraft lignin and the role of mixing in oil-in-water emulsions
(2023)Oil-in-water emulsions are widely used in various industrial applications such as food, pharmaceuticals, and cosmetics. An oil-in-water emulsion is a colloidal system in which oil droplets are dispersed in water with the ... -
Thermophilic anaerobic membrane bioreactor for pulp and paper sludge treatment
(2018)Pulp and paper mills generate a significant amount of organic waste (primary and secondary sludge) that requires treatment and disposal. Currently, pulp and paper sludge (PPS) is either dried for incineration or used for ...
