“…In seawater, concrete and any natural or artificial substrata quickly become fouled [33][34][35]. The term "fouling" is defined as the colonization of any solid surface, living or dead, natural or artificial by living organisms in a marine or wet environment [36][37][38][39]. This colonization can be divided into two main stages, micro-fouling and macro-fouling, which are characterized respectively by the formation of bacterial biofilm on the surface and the adhesion of macro-organisms such as algae, barnacles and larvae (macro-fouling) (Fig.…”

Civil engineers have a responsibility to take measures to protect marine biodiversity by selecting more bioreceptive construction materials in the design of marine infrastructure, for better biodiversity conservation. In this study, it was shown that pre-carbonation of cementitious materials accelerates their bacterial colorization by lowering the pH of their surface. It has been shown both in the laboratory and in-situ tests that the bacterial colonization of cementitious materials is influenced by the pH and the type of cement. By comparing the bacterial colonization of Portland cement mortars, CEM I, and slag cement, CEM III, mortars, it was found that the CEM III mortars are more bioreceptive than the CEM I mortars. This study presented and verified a novel experimental laboratory approach which can be used to evaluate the bacterial colonization (bioreceptivity) of cementitious materials in marine environment. The approach could be taken up in future recommendations to enable engineers to eco-design more eco-friendly marine infrastructure and develop green-engineering projects.

“…Generally, the saline feed water biofouling potential is influenced by several interrelated factors including microorganisms' concentration; content of readily biodegradable compounds; nutrients concentration and composition in the source water; temperature; the salinity of the feed water as well as operating parameters such as cross-flow velocity [11,25,26].…”

This study presents recent literature that sheds light on the SWRO membrane biofouling, Inventory of causes, consequences, measurement, and possible solutions. In particular, biofouling of SWRO is considered as one of the challenges faced by seawater desalination today. For seawater desalination, mitigating membrane biofouling is essentially required and yet to be overcome. Specific shortcomings and prospective solutions are reviewed towards understanding the biofouling mechanism, pretreatment impacts, level of assimilable nutrients, and real-time monitoring. Accordingly, this review aims to address recent advances in biological fouling measurements and control to better understand biofouling and the best ways of dealing with such a challenging issue.

“…Therefore, it is expected Ag-electrode has potential applications for anti-biofouling and ORR processes, that will not only mitigate the biofouling problem but will also enhance the catalytic reduction of oxygen (Farhat et al, 2019;Noori et al, 2018). Briefly, in situ preparation of antibiofouling material was achieved from wastewater, which will reduce the cost of antibiofouling materials for sustainable resource recovery or waste valorization.…”

Precious metals recovery and wastewater treatment using the microbial fuel cell (MFC) is an attractive approach for a sustainable environment. Silver recovery from wastewater and its valorization in the form of silver nanoflakes (AgNFs) brings back waste material to production stream and helps in transition from linear to circular economy. In the present study, bioelectrochemical performance of MFC fed with silver laden artificial wastewater (MFC-Ag) was compared with MFC fed with potassium ferricyanide (MFC-FC) and MFC fed with phosphate buffer as catholyte (MFC-blank). High silver removal (83 ± 0.7%) and recovery (67.8 ± 1%) efficiencies were achieved from MFC-Ag after 72 h operation. The maximum power density (3006 mW/m 3 ) and current density (34100 mA/m 3 ) of MFC-Ag were found to be significantly higher than the MFC-FC and MFC-blank. High chemical oxygen demand (COD) removal efficiency of MFC-Ag (82.7 ± 1.5%) compared with MFC-FC (76 ± 2) highlighted the suitability of silver laden wastewater as a cost effective catholyte. The high coulombic efficiency (8.73 ± 0.9 %) and low solution resistance (24.38 Ω) for MFC-Ag also indicate the potential of silver laden wastewater for large scale applications. Analytical characterizations of electrochemically recovered silver revealed the pure (99%) and crystalline AgNFs with a mean diameter of 18 ± 1.2 nm on the cathode surface. Furthermore, a significant anti-biofouling activity of recovered AgNFs indicate the valorization of waste by current study with potential applications in several industrial and environmental processes. Our method has diverse potential to scale up the MFC technology for industrial waste management as a closed loop process with minimum facilities and higher sustainability.
