“…Regarding the predictability, it is mentioned that the growth biofilm model is here parametrized (J max , t) from seawater bio- films using literature data [21,22] as a proof-of-concept. It can be adapted to various ecologies (other surface or industrial waters) by adjusting these parameters.…”

Industrial cooling circuits with wet cooling towers use raw water to remove residual heat from industrial processes. These circuits are very prone to fouling and particularly biofouling. This work proposes a compartmental model built from a full hydrodynamic characterization (using computational fluid dynamics and experimental, local, and system data) of an industrial cooling circuit and implemented with a biofilm growth model which considers kinetic (temperature, concentrations) as well as hydrodynamic (internal and external transfer) limitations. It can therefore predict the biofouling growth per surface unit in the different part of the circuit, considering the various hydrodynamic conditions, while taking only a few minutes to simulate a full year considering season variation of temperature and water quality.

“…Over time, the biofilm can grow and become thicker, eventually leading to the formation of a full-fledged community of marine organisms on the surface. The formation of marine biofouling can be influenced by a variety of factors, such as water temperature, nutrient availability, water flow, and the composition of the surface itself [6]. For example, surfaces that are smooth and free of imperfections may be less prone to biofouling than rough or irregular surfaces.…”

Biofouling is a significant problem that affects renewable energy marine structures (REMS), such as wind turbines and those designed for wave or tidal energy exploitation. Marine organisms, including algae, barnacles, and mollusks, attach themselves to the surface of these structures, which can lead to reduced efficiency and increased maintenance costs. In addition, biofouling can also cause corrosion, which can compromise the structural integrity of the offshore platforms. To combat this problem, several methods have been developed, including anti-fouling coatings, physical methods, and biological methods. Each method has its advantages and disadvantages, and the most effective solution often depends on the specific type of fouling and the location of the offshore structure. Effective biofouling prevention is essential for the safe and efficient operation of offshore structures and the protection of marine ecosystems. To prevent the spread of invasive species, an innovative ceramic coating has been designed and tested in accordance with ASTM-D3623 procedure. The investigation results revealed that, after four years of experimentation in a real environment, the biofouling growth observed in the splash zone of the antifouling paint was 129.76% higher than that of the titanium-based ceramic coating and it is expected that this difference will continue to grow over time.

“…Since the 1980s, over 4,000 studies about antiscaling and anti-fouling with EMF have been reported [2,6,7]. EMF has proved its anti-scaling effectiveness through numerous applications and publications, indicating that EMF is an indispensable technique to control scale [8].…”

Electromagnetic field (EMF) treatment has demonstrated its superior efficiency and great potential in inhibiting scale formation in industrial plants. Despite the numerous studies focusing on improving the performance of EMF devices, there is still limited understanding of how the frequency affects the anti-scaling process. This problem restricts the development and optimization of the sweep frequency EMF technique, which is assumed to have a better anti-scale performance. In this work, experimental studies were performed to study the effect of the sweep frequency EMF on the precipitation of CaCO 3 under circulating flow conditions. The results showed that the sweep frequency EMF could stimulate the homogeneous crystallization of CaCO 3 in the simulated hard water solution, and the direct reaction between Ca 2+ and HCO 3 was the primary reaction route. The sweep frequency had a more pronounced effect on the scale formation process than the output current of the EMF device. The sweep frequency value was inversely correlated with the scale formation. The effect mechanism of sweep frequency on the scale formation process was discussed.
