TL;DR: In situ hybridization revealed that bacteria belonging to the genus Nitrosomonas were the numerically dominant ammonia-oxidizing bacteria in both types of biofilms, and Nitrospira-like bacteria were the main nitrite- oxidizingacteria in both type ofBiofilms.

TL;DR: In this paper, the authors investigated the rejection of organic micropollutants such as disinfection byproducts (DBPs), endocrine disrupting compounds (EDCs), and pharmaceutically active compounds (PhACs) by nanofiltration and reverse osmosis (RO) membranes as a function of their physico-chemical properties and initial feed water concentration.

TL;DR: In this paper, the authors examined the ability of RO membranes to retain neutral (uncharged) endocrine disrupting compounds (EDCs) and pharmaceutically active compounds (PhACs).

TL;DR: It is reported that the unsaturated hydrocarbon molecule cyclic-C3H2 resides in the infalling rotating envelope, whereas sulphur monoxide is enhanced in the transition zone at the radius of the centrifugal barrier (100 ± 20 au), which is the radius at which the kinetic energy of the inf falling gas is converted to rotational energy.

TL;DR: FISH and 16S rRNA gene sequence analyses revealed that a specific phylogenetic group of bacteria, the Betaproteobacteria, probably played a major role in development of the mature biofilms, which led to the severe irreversible membrane biofouling.
