Biofouling is an important factor to consider when calculating the energetic efficiency of tidal farms. Despite fact that biofouling effects have been widely investigated in past for naval applications, very few studies concern turbines. This paper proposes a numerical approach assess impact on turbines, which efficient testing many configurations. Two turbulence models are tested (RANS k-ω SST...

This paper reports on preparation of polyamide membrane with addition of silver nanoparticles (AgNPs). AgNPs act as antibacterial agents that are less susceptible to membrane’s biofouling by interfacial polymerization (IP) method. AgNPs was synthesized via green route which has been reported previously. Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (ATR-FTIR), Field emiss...

Smooth, durable, ultrathin antifouling layers are deposited onto commercial reverse osmosis membranes without damaging them and they exhibit a fouling reduction. A new synergistic approach to antifouling, by coupling surface modification and drinking-water-level chlorination is enabled by the films' unique resistance against chlorine degradation. This approach substantially enhances longer-term...

Polymeric membrane ion-selective electrodes (ISEs) have been widely applied in environmental analysis. In many cases of practical relevance, however, when these sensors are complex samples, they could suffer from problems biofouling (related to microorganisms and biofilms) which may shorten the sensors’ lifetimes cause measurement errors. Herein, we describe a robust effective method endow ISE ...

Marine growth has been observed to cause a drop in the horizontal and vertical velocities of underwater gliders, thus making them unresponsive needing immediate recovery. Currently, no strategies exist correctly identify onset marine for gliders only limited data sets biofouled hulls exist. Here, field test conducted first investigate impact on dynamics power consumption then design an anomaly ...
