One of the key parameters in Fluidized Bed reactors is the control of biofilm thickness and configuration. The effect of upflow velocity on performance and biofilm characteristics of an Anaerobic Fluidized Bed Reactor was studied in treating Currant wastewater at various loading rates. The reactor used this study was made of a plexiglass column being 60 mm diameter, 140 cm height, and a volume ...

Axial Flow Chromatography (AFC) is widely used for the purification of therapeutic Monoclonal Antibodies (MAbs). However, AFC columns can generate high pressure drops across the resin bed, preventing operation of the column at high flow rates especially at pilot or manufacturing-scales. Radial Flow Chromatography (RFC) was developed to provide lower pressure drops during chromatographic separat...

We consider the application of mixed-integer linear programming (MILP) solvers to the minimization of submodular functions. We evaluate common large-scale linear-programming (LP) techniques (e.g., column generation, row generation, dual stabilization) for solving a LP reformulation of the submodular minimization (SM) problem. We present heuristics based on the LP framework and a MILP solver. We...

Atrazine (ATZ) is an herbicide used for increased food production due to its weed and pesticide control capacity in different crops. However, ATZ a chemical compound that harmful the environment human health, and, unfortunately, it has been detected surface groundwater. Therefore, aim of this paper was perform adsorption from synthetically contaminated water sample using packed-bed column with ...

In this study, the adsorption of a multicomponent mixture active pharmaceutical compounds, such as Venlafaxine (VLX), Trazodone (TRZ) and Fluoxetine (FLX), was studied in biochar fixed-bed column. The selection appropriate (eucalyptus, grapevine cane holm tree biochar) an adsorbent carried out through batch assays. An insight into mechanism its correlation with chosen biochars performed, showin...

In this study, the removal of bromate, a regulated ozone by-product, was evaluated using strong-base anion (SBA) exchange resin in batch and column experiments. The kinetics studies mode showed that film diffusion-controlled bromate SBA isotherm Langmuir model fitted experimental results with maximum capacity 296.66 mg BrO3−/g (~1.3 meq/mL resin). fixed-bed studies, breakthrough curves were obt...
