MR dampers are smart dampers that improve structural performance through vibration control. Vibration of tall or flexible structures and structural elements induced by dynamic loads such as wind and earthquakes can cause severe damage to the structure and discomfort for individuals. Therefore, dampers are commonly installed to increase the energy dissipation capacity and mitigate large amplitude vibrations. MR dampers are gaining recognition because of the unique rheological properties offered by the magnetically sensitive MR fluid. Changes to the current level, along with the frequency and amplitude of vibration, affect the force-displacement and force-velocity hysteresis relationship and thus the amount of …
Enzymatic Removal Of Sulfonated Azo Dyes From Synthetic Textile Effluents Using Soybean Peroxidase, Temidayo Oyelere
Enzymatic Removal Of Sulfonated Azo Dyes From Synthetic Textile Effluents Using Soybean Peroxidase, Temidayo Oyelere
Electronic Theses and Dissertations
The textile industry and other colour-oriented industries utilize azo dyes in extensive amounts. Dye effluents are recalcitrant to natural biodegradation, hence, causing toxic effects on the environment. Physiochemical treatment generates sludge which requires secondary disposal; advanced oxidation processes (AOPs) are cost and energy intensive; biological methods like anaerobic treatment via bacteria generate aromatic amines which are mutagenic and carcinogenic. A promising alternative that has shown great success in the treatment of wastewater is the enzymatic method. This thesis reports the enzymatic degradation of Reactive Black 5 (RB5), Acid Orange 7 (AO7), and Acid Orange 20 (AO20) from synthetic textile effluents …
