The performance of a hybrid bubble column/biofilter (HBCB) bioreactor for the removal of dichloromethane (DCM) from waste gas streams was studied in continuous mode for several months. The HBCB bioreactor consisted of two compartments: bubble column bioreactor removing DCM from liquid phase and biofilter removing DCM from gas phase. Effect of inlet DCM concentration on the elimination capacity ...

In this paper, experimental data on the drying kinetics of corn in a packed and fluidized bed are presented. Experimental research was conducted on a laboratory apparatus. Corn was used as a material because of its significance in agriculture and the food industry. An analysis of the influence of the operational parameters (the drying medium velocity i. e. the flu...

Abstract: The selection of a suitable type of reactor for the reaction with enzymes immobilized on the carriers is extremely important to industry. In this study the possibility of using pre-selected cellulose-based carriers (Granocel) to conduct the reaction in a stirred batch reactor and a fixed-bed reactor was investigated. It was shown that non-activated Granocel did not undergo compression...

The consolidation of colloidal particles in drying colloidal dispersions is influenced by various factors such as particle size and shape, and interparticle potential. The capillary pressure induced by the menisci, formed between the top layer of particles in the packed bed, compresses the bed of particles while the constraints imposed by the boundaries result in tensile stresses in the packing...

Carbon dioxide capture is a key issue in climate change mitigation. For decades the removal of carbon dioxide has been an essential step in many industrial processing operations such as the synthesis of ammonia, natural gas purification, and oil refining. In this study, a rotating packed bed has been designed for absorption of carbon dioxide from an air stream. The rotating packed bed is a comp...

The effect of different water matrices on the photocatalytic degradation dissolved pharmaceuticals was explored. focus efficiencies in wastewater effluent from a bioreactor and central treatment plant comparing results with deionized H2O. compounds tested included: oxytetracycline, marbofloxacin, ibuprofen, diclofenac, phenytoin, ciprofloxacin, sulfamethoxazole. For experiments performed this s...
