“…It can be concluded that the cake layer was responsible for the main fouling of both PAC/UF and parallel UF processes. This result is consistent with the findings of Castaing et al [14], who indicated that cake formation was the main fouling mechanism of the immersed MF and UF membranes used for removing micro-algae from seawater.

“…A study carried out by Qu et al [10] found that high molecular weight and hydrophilic organics accounted for the major portion of algal extracellular organic matter which was comprised of protein-, polysaccharide-and humic-like substances. Nevertheless, both proteins and polysaccharides are biodegradable matters in membrane bioreactors [11]; membrane bioreactor could be an effective way to control the fouling of algal-rich water for the advantage of biodegradation of organics and excellent solid/liquid separation in a single tank [12][13][14][15].…”

“…In reverse osmosis, water is projected to a membrane where the separation of water and salt occurs. This process uses micro membranes up to 0.2-µm of thickness which are capable of filtering microalgae such as (Castaing, 2010). After the desalination process, the water undergoes treatment for chemical and micro biotic stabilization, palatability and pH correction.…”

“…Reverse osmosis occurs with water going through a series of high pressure membranes. This process is essential to disaggregate the organisms in the ballast water because of the membranes denseness (Castaing, 2010). Chemical substances that eliminate organisms might be added during pre and post treatment.…”

This paper completes an exploration analysis of onshore ballast water treatment alternatives at major ports. The authors had presented results for option (1) ballast water treatment onshore installed in two iron ore ports in 2012 applying the discrete events simulation model. Now, two more options are presented: (2) mobile and (3) desalination reception facilities. The previous simulation model developed called TRANSBALLAST, was adapted to consider these two new alternatives. This model was applied to the same ports presented in 2012 and this evaluation also includes one more port with 50 million tons annually (Mta) of iron ore transport capacity. The results uncovered that for (2) there is an increase of 1.90 days on the average waiting time of ships that moored at Port 1. In (3), the average waiting time and berth occupation rates were observed to remain the same presented in (1). One of the major differences between the systems consists in catching sea water to increase the desalination plant operational capacity. Among those three onshore ballast water treatment alternatives, (2) does not impact port terminals infrastructure. Additionally, option (2) could be offered to ports users as a ballast water treatment service and ship-owners might not need any onboard ballast water treatment system. (3) Might be feasible to ports regions without enough water supplies solving two issues: transfer of invasive species from ballast water and water recycling.Este ensayo realiza un análisis exploratorio de alternativas de tratamiento de agua de lastre en tierra en puertos principales. Los autores habían presentado resultados para la opción (1) del tratamiento en tierra de agua de lastre instalado en dos puertos de minerales de hierro en 2012 aplicando el modelo de simulación de eventos discretos. Ahora, se presentan dos opciones adicionales: (2) móvil e (3) instalaciones de recepción de desalinización. El modelo de simulación anterior desarrollado que se denominó TRANSBALLAST, fue adaptado para considerar estas dos nuevas alternativas. Este modelo fue aplicado a los mismos puertos presentados en 2012 y esta evaluación también incluye un puerto adicional de 50 millones de toneladas al año (Mta) de capacidad de transporte de minerales de hierro. Los resultados concluyeron que para (2) hay un aumento de 1.90 días de promedio de tiempo de espera de naves que atracaron en el Puerto 1. En (3), el tiempo de espera promedio y las tasas de ocupación de atraque fueron observadas para mantenerse igual que las presentadas en (1). Una de las principales diferencias entre los sistemas consiste en atrapar agua de mar para aumentar la capacidad operacional de la planta de desalinización. Entre esas tres alternativas de tratamiento de agua de lastre, (2) no tiene un impacto en la infraestructura de los terminales de puertos. Adicionalmente, la opción (2) puede ser ofrecida a usuarios de puertos como un servicio de tratamiento de agua de lastre y los propietarios de naves podrían no necesitar ningún sistema de tratamiento de agua de lastre...

“…Some researcher has mentioned that the selectivity is better with small pore size, as the retention of cells is higher (Rossignol et al 1999) and pore clogging is minimal (Rossi et al 2004). The preferred membrane filters are however narrowed between two pore sizes, microfiltration (MF) and ultrafiltration (UF) (Rossi et al 2004;Castaing et al 2010;Rossignol et al 1999;Zhang et al 2010).…”
