This paper describes the characterization and evaluation of various RO/NF membranes for the treatment of seasonally brackish surface water with high organic contents (TOC ≈21 mg/L). Twenty commercially available RO and NF membranes were initially evaluated by performing controlled bench-scale flat-sheet tests and surface characterization. Based on the results, four low pressure RO membranes wer...

Alteromonas macleodii is a marine bacterium involved in the early stages of biofouling on ship hulls treated with copper as an antifouling agent. We report here the draft genome sequences of an A. macleodii strain isolated from copper coupons and three laboratory mutants grown long-term at elevated copper levels.

Biofouling is a serious problem in the food industry, and one way to control biofouling using topographically patterned surfaces. This vitro study used laser surface texturing process produce six differently topographies which were analysed for their topography wettability with repeated fouling cleaning. The surfaces spray-inoculated Staphylococcus aureus suspended either sterile distilled wate...

Fouling due to biofilms composed primarily of microorganisms and extracellular polymeric substances is a significant hindrance to membrane filtration in water treatment. The goal of this work was to use a reactive membrane surface to reduce membrane biofouling by coating a ceramic ultrafiltration membrane with the nanoparticulate photocatalyst, TiO2. 10-Day biofilm growth experiments were condu...

flora and fauna of rocky coastal habitats are versatile in adapting to the prevalent tidal fluctuations. the current study was undertaken to evaluate the diversity of fouling and associated species around the port blair coastal areas of andaman and nicobar islands. except tss, the hydrographical parameters (temperature, salinity, ph and dissolved oxygen) did not significantly vary among the 5 s...

Nowadays, forward osmosis (FO) with many advantages in water treatment, are so attractive for researchers and investigators that the studies are going to optimize and increase its efficiency. However one of the most controversial operating malfunctions of FO process is fouling that limits the FO global application. In the following research, vertically aligned carbon nanotube (VACNT) on alumina...
