Recent papers have described new bioreactor designs. Most innovations addressed either oxygen transfer, shear induced by stirring, control of water activity in organic phase systems or waste biotreatment. The latest developments in these key areas are reviewed and discussed.
Biodegradation of azo dyes is difficult due to their complex structures and low BOD to COD ratios. In the present study, the efficiency of using Fenton's reagent (H2O2 + Fe2+) as a pretreatment process to enhance microbial transformation of reactive black 5 (RB5) in an aqueous system was evaluated. The RB5 with an initial concentration of 250 mg/L was decolorized up to 90% in 60 h by using a ba...
In this paper, a comparative study of the treatment of raw and biotreated (upflow anaerobic sludge blanket, UASB) textile dye bath effluent using advanced oxidation processes (AOPs) is presented. The AOPs applied on raw and biotreated textile dye bath effluent, after characterization in terms of COD, colour, BOD and pH, were ozone, UV, UV/H2O2 and photo-Fenton. The decolorization of raw dye bat...
When a works of art or a monument is completed, it actually starts a new life, a new life influenced by the overall context where this art piece will be placed and/or exhibited. It is like a newborn that starts its life adventure. The living context is not always favorable for the new entity, and different risks may occur, depending on the deterioration agents and the duration of the exposure. ...
The strength and deformation properties of maritime geotechnical structures made primarily calcareous sand are critical for project safety. geogrid reinforcement is developed as a promising approach to improve the mechanical sand. This study investigates property biomodified via microbially induced calcite precipitation (MICP) process effectiveness A series unconsolidated undrained triaxial exp...
