Biofouling is a critical issue in membrane water and wastewater treatment as it greatly compromises the efficiency of the treatment processes. It is difficult to control, and significant economic resources have been dedicated to the development of effective biofouling monitoring and control strategies. This paper highlights the underlying causes of membrane biofouling and provides a review on r...

These days, many marine autonomous environment monitoring networks are set up in the world. These systems take advantage of existing superstructures such as offshore platforms, lightships, piers, breakwaters or are placed on specially designed buoys or underwater oceanographic structures. These systems commonly use various sensors to measure parameters such as dissolved oxygen, turbidity, condu...

Biofouling is detrimental to the hydrodynamic performance of ships. In spite of advances in hull coating technology, a ship must usually undergo underwater hull cleaning to remove biofouling during her in-service time. However, some cleaning practices may also lead to decreased lifetime of the fouling-control coating. Therefore, cleaning forces should be minimized, according to the adhesion str...

Biofouling, also known as barnacles and slime, may not be the trendiest, high-tech topic of conversation in the world of operational energy. Most would rather discuss a new weapon system or innovative green technology that allows Sailors and Marines to increase operational tempo or achieve more efficient fuel consumption. What most people don’t realize is that biofouling may actually represent ...

l Biofoulingmitigationmeasures for optical ports can extend the duration of oceanographic deployments, but there have been few quantitative studies of field performance. Results are presented from a 4-month field test of a stereo-optical camera system intended for long-term environmental monitoring of tidal turbines. A combination of passive (copper rings and ClearSignal antifouling coating) an...

This review discusses the state-of-the-art of research into biocorrosion and the biofouling of metals and alloys of industrial usage. The key concepts needed to understand the main effects of microorganisms on metal decay, and current trends in monitoring and control strategies to mitigate the deleterious effects of biocorrosion and biofouling are also described. Several relevant cases of bioco...

Biofouling“ is referred to as the unwanted deposition and growth of biofilms. This phenomenon can occur in an extremely wide range of opportunities ranging from colonization of medical devices, production of ultrapure, drinking and process water, fouling of ship hulls, pipelines and reservoirs. It seriously damages the efficacy of membrane processes by forming a secondary membrane which, at a c...

Ultrafiltration, nanofiltration membranes and feed spacers were hydrophilized with polydopamine and polydopamine-g-poly(ethylene glycol) surface coatings. The fouling propensity of modified and unmodified membranes was evaluated by short-term batch protein and bacterial adhesion tests. The fouling propensity of modified and unmodified membranes and spacers was evaluated by continuous biofouling...

Membrane systems are used increasingly for water treatment, recycling water from wastewater, during food processing, and energy production. They thus are a key technology to ensure water, energy, and food sustainability. However, biofouling, the build-up of microbes and their polymeric matrix, clogs these systems and reduces their efficiency. Realizing that a microbial film is inevitable, we en...
