“…The electromagnetic frequency range can be divided into separate bands, with low-frequency (long wavelengths) radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelengths). The EM waves in each of those bands have different characteristics, namely how they are produced, interaction with measured material, and their practical applications [5,6].…”

Structural health monitoring (SHM) is an important aspect of the assessment of various structures and infrastructure, which involves inspection, monitoring, and maintenance to support economics, quality of life and sustainability in civil engineering. Currently, research has been conducted in order to develop non-destructive techniques for SHM to extend the lifespan of monitored structures. This paper will review and summarize the recent advancements in non-destructive testing techniques, namely, sweep frequency approach, ground penetrating radar, infrared technique, fiber optics sensors, camera-based methods, laser scanner techniques, acoustic emission and ultrasonic techniques. Although some of the techniques are widely and successfully utilized in civil engineering, there are still challenges that researchers are addressing. One of the common challenges within the techniques is interpretation, analysis and automation of obtained data, which requires highly skilled and specialized experts. Therefore, researchers are investigating and applying artificial intelligence, namely machine learning algorithms to address the challenges. In addition, researchers have combined multiple techniques in order to improve accuracy and acquire additional parameters to enhance the measurement processes. This study mainly focuses on the scope and recent advancements of the Non-destructive Testing (NDT) application for SHM of concrete, masonry, timber and steel structures.

“…The dissolved electrodes form a coagulant species that destabilize and trap pollutants in water and wastewater in the form of suspended particles causing them to form flocs and precipitate, which results in removing pollutants (Papadopoulos et al 2020). Electrocoagulation process is highly adopted due to the installation and maintenance system being simple, operation cost is low, and production of sludge is a small amount and its ability to combine with other treatment process such as ultrasonic, microwave, and ozone (Sharma and Mane 2017;Hashim et al 2020Hashim et al , 2021Abdulhadi et al 2021;Das et al 2021).…”

Wastewater generated from different sources affects the health of living organisms and the natural environment due to the availability of different pollutants. Electrocoagulation (EC) is a good technology implemented for wastewater treatment before discharging to an environment as effluents. The electrocoagulation process is an effective method to the remove the color, chemical oxygen demand (COD), turbidity, and consumption of less energy from wastewater by considering different operating parameters. In this study, the major operating parameters for the electrocoagulation process such as pH (3–7.50), electric current (0.03–0.09 A), electrolytic concentration (1–3 g/L), the distance between electrodes (1–2 cm), electrolysis time (20–60 min) and combination of electrodes (Fe–Fe and Al–Al) were studied. The maximum removal of color–94.40%, COD–97.02%, and turbidity–90.91% with required energy consumption –36kWhr/m3 was obtained at the electric current–0.09 A, electrolyte concentration–3 g/L, pH–7, electrode combination–Fe–Fe, and distance between electrodes–3 cm, respectively. The studied parameters were affected the removal % color, % COD, % turbidity, and also the consumption of energy depending on the desired setup of fixed values of the parameter. Consumption of energy and electrode dissolution is related to the cost of operating in electrocoagulation in addition to the cost of labor and the small amount of sludge produced for disposal.

“…The theme of sustainability has gained considerable attention in recent years via environmental organizations and departments worldwide, particularly with regard to the issues of addressing the pollution of the basic elements of the environment (water, air, soil) and the sustainability required for treatment techniques (Furley et al 2018). For instance, water bodies are facing severe deterioration due to the discharge of wastewaters, which results in a remarkable increase in heavy metals (Abdulla et al 2020;Abdulraheem et al 2020), coloring agents (Abdulhadi et al 2019;Aqeel et al 2020), nutrients (Alenezi et al 2020;Al-Marri et al 2020;Khalid et al 2020aKhalid et al , 2020b, phenols (Emamjomeh et al 2020a(Emamjomeh et al , 2020b, geosmin (Ryecroft et al 2019), fluoride (Alhendal et al 2020), organic pollutants (Abdulhadi et al 2021;Alyafei et al 2020;Zanki et al 2020), viruses and bacteria (Hashim et al 2020a(Hashim et al , 2020bHashim et al 2021;Khalid et al 2020aKhalid et al , 2020b, turbidity (Alenazi et al 2020;Alnaimi et al 2020) and other pollutants (Emamjomeh et al 2020a(Emamjomeh et al , 2020bHashim et al 2020aHashim et al , 2020bKadhim et al 2020b;Mohammed et al 2020). Air quality is also deteriorating due to the increasing emissions from human activities (Grmasha et al 2020;Kadhim et al 2020a;Shubbar et al 2020aShubbar et al , 2020b, such as cement industries (Majdi et al 2020;…”

Sustainable development is based on environmental, social, economic, and technical dimensions. In this study, the sustainability of wastewater treatment techniques in urban areas of Iraq was assessed using a multi-criteria decision analysis (MCDA)/the weighted sum model (WSM). The analysis was performed on 13 operating wastewater treatment plants in 10 provinces, Iraq using a questionnaire sheet with the assistance of 52 specialists in the Ministry of Municipalities and Public Works, Iraq. Four types of wastewater treatment techniques (Conventional Treatment, Oxidation Ditches, Aeration Lagoons, and membrane bio-reactor (MBR)) were assessed. The environmental, social, economic, and technical dimensions were represented by 11, 5, 7, and 4 indicators, respectively. The main results of this study indicate that the sustainability of MBR recorded the highest total importance; the order of the total importance from the highest to the lowest was: MBR > Oxidation Ditches > Aeration Lagoons > Conventional Treatment. The environmental dimension proved its dominance in the four studied treatment techniques' sustainability as it recorded the maximum contribution to sustainability. While the technical dimension recorded the least contribution to sustainability, the order from the highest to the lowest was: Environmental Dimension > Economic Dimension > Social Dimension > Technical Dimension.
