Biodegradation Modeling of Nitrophenolic Pollutant in a Slurry Bubble Reactor

Biodegradation kinetics of 4-nitrophenol (PNP) in aqueous solution by a gram negative soil bacterium, Ralstoniaeutropha was firstly studied in a small scale batch reactor. The degradation of PNP was evaluated at initial PNP concentrations ranging from 3 mg/L to 14 mg/L. The rate of PNP consumption by the bacterium culture was modeled using Monod and Contois kinetics in batch condition. PNP degr...

Bye, bye blockbusters, hello niche busters.

time for a great white shark named Bruce. A mechanical beast weighing 1.5 tonnes, Bruce was the star of Jaws, a movie that grossed US$260 million in the United States, ushering Hollywood into the summer blockbuster era. Like the movie industry, the pharmaceutical sector has in recent decades come to rely on annual blockbusters to drive profits. But it appears the blockbuster model is broken. Un...

Bubble Size in a Cocurrent Fiber Slurry

Bubble diameter measurements in a two-dimensional cocurrent bubble column are obtained using a gas−liquid−solid system in which the solid component is a cellulose fiber. Flash X-ray radiography, a noninvasive measurement technique, is used to record bubble size in the opaque slurry at various operating conditions. Results are presented for a range of fiber mass fractions (0 ≤ C ≤ 1.5%), a range...
