TL;DR: A diverse and unstable bacterial population was indicated throughout the 100-day period, with spikes in feed strength causing significant changes in community structure, and the MBR system was able to meet effluent quality parameters approximately 90% of the time.

TL;DR: The results suggest that stand-alone ultrasonic treatment systems for ballast water, operating at 19-20 kHz, may be effective for planktonic organisms >100 microm in size, but smaller planktonics organisms such as phytoplankton and bacteria will require treatment by an additional or alternative system.

TL;DR: Evidence that S. aureus cells on a QAS‐coated planar surface are not exposed to a sufficient number of QAS molecules to produce significant mortality is provided, which has important implications for the development of self‐decontaminating coatings.

TL;DR: In this article, the effects of biofouling and seawater exposure to high-sulfur diesel, ultralow sulfur diesel (ULSD), Fischer-Tropsch synthetic diesel, fatty acid methyl ester (FAME) biodiesel, and hydrotreated renewable diesel fuels were investigated.

TL;DR: In this article, the authors investigated the disinfection of sewage and several bacterial pure cultures relevant to sewage using ultrasound produced by the magnetostrictive material, TERFENOL-D. Particular attention was paid to measuring the ultrasonic exposure time and energy density required to kill bacteria.
