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 ...
Amine is one of candidate solvents that can be used for CO2 recovery from the flue gas by conventional chemical absorption/desorption process. In this work, we analyzed the impact of different amine absorbents and their concentrations, the absorber and stripper column heights and the operating conditions on the cost of CO2 recovery plant for post-combustion CO2 removal. For each amine solvent, ...
Concentration ofradon in supply air 3 pCi/1 Minimum reduction factor for radon 100 Time for which reduction must be maintained 10 days ^ 7 From the tests completed recently2 at the SNO underground laboratory at the INCO Creighton mine it was found that activated charcoal has considerable adsorption capacity even at room temperature for the removal ofradon from compressed air. It was also f...
The performance of particulate-laden SO(2) scrubbing in a modified tapered bubble column with internals is reported in this article. The presence of particles improved the particulate-laden SO(2) removal efficiency to about 15% that was elucidated by the facilitated adsorptive mass transport. Experimentation revealed that nearly 100% removal efficiency of particulate-laden SO(2) was achievable ...
Removal of benzalkonium chloride (BKC) from aqueous streams by polymeric resins XAD-7 and XAD-16 was investigated. Adsorption equilibrium isotherms of BKC from water were measured in a batch adsorber at different temperatures and ionic strengths of the external phase. In addition, the influence of an organic solvent (ethanol) on the phase equilibrium was studied. The experimental data was corre...
A laboratory investigation provided preliminary comparison of trace element contaminant water treatment capabilities for four iron-based filter materials. The iron-based filter materials tested were zero-valent iron (ZVI), porous iron composite (PIC), sulfur modified iron (SMI), and iron oxide/hydroxide (IOH). Two types of trace element contaminant solutions were tested, one combined As, Cr, an...
Nanoparticles are being intensively investigated because of their unique optical, electrical and catalytic properties which make them a potential material for utilization in the field of medicine electronic and environmental issues. This paper is concerned with the removing a heavy metal, Chromium, from its aqueous solution by Iron oxide nanoparticle filtration. Solutions of varying chromium co...
A continuous fixed bed study was carried out by using PAN-oxime-nano Fe2O3 as a sorbent for the removal of nitrate from aqueous solution. The effect of factors, such as flow rate (2, 5 and 7 mL/min) and bed depth (5, 10 and 15 cm) were studied. Data confirmed that the breakthrough curves were dependent on flow rate and bed depth. The adsoption capacities observed in diffent conditions of flow r...
