“…Sewer pipes are susceptible to corrosion, which causes perforations in their walls. The main cause of leakage and failures in sewerage systems is external corrosion (Foorginezhad et al, 2021); "Corrosion is the main cause of most metal pipe failures.…”

The malfunction of sewerage systems and rain water drainage networks is perceived as a very crucial problem by authorities in Côte d'Ivoire, both from an environmental point of view as well as the associated maintenance costs. This paper discusses the state of the sewerage systems, the malfunctions and environmental concepts used to categorize the problems, and the methodological options to prioritize the various management solutions. This review also presents the selection of decision support tools for sewerage asset management. The tools were classified according to their capability and functionality. The working principle of each of these tools was described and the corresponding data requirements were determined. Moreover, the paper discussed the problems associated with the use of existing tools and presents a perspective on future research needs in the field of decision support tools. This paper represents a comprehensive review of the sewage systems management challenges and can serve as a reference document for other developing countries in Sub-Saharan Africa.

The accurate and reliable monitoring of ventilation parameters is key to intelligent ventilation systems. In order to realize the visualization of airflow, it is essential to solve the airflow reconstruction problem using few sensors. In this study, a new concept called independent cut set that depends on the structure of the underlying graph is presented to determine the minimum number and location of sensors. We evaluated its effectiveness in a coal mine owned by Jinmei Corporation Limited (Jinmei Co., Ltd). Our results indicated that fewer than 30% of tunnels needed to have wind speed sensors set up to reconstruct the well-posed airflow of all the tunnels (>200 in some mines). The results showed that the algorithm was feasible. The reconstructed air volume of the ventilation network using this algorithm was the same as the actual air volume. The algorithm provides theoretical support for flow reconstruction.

“…Therefore, sewer pipes may crack and collapse [3,4]. The subsequent repair and replacement of damaged sewer pipes are costly, and conventional corrosion preventing methods are too expensive [5,6]. The corrosion in sewer systems is mainly caused by the biogenic sulfuric acid reactions with the concrete cementitious materials [7][8][9][10].…”

The effect of synthesized Cu2O on the microbial corrosion inhibition of urban sewer systems

The microbial corrosion of reinforced concrete sewers was inhibited by synthesized cuprous oxide (Cu2O) nanoparticles. The antibacterial characteristics of Cu2O on Acidithiobacillus thiooxidans were investigated by temporal variation of pH, turbidity, and bacterial counting. Three reinforced concrete samples with different weight percentages of electrodeposited Cu2O (0.06 wt%, 0.055 wt %, 0.05 wt %) were used. The bacterial counting showed that the number of bacteria in samples with 0.06, 0.055, and 0.05 wt% of Cu2O was 4.82, 4.42, and 2.94 times lower than the blank sample (BS), respectively. After bacterial growth, the optical density measurement showed that the percentage of turbidity enhancement for samples with 0.06, 0.055, and 0.05 wt% of Cu2O were 108%, 118%, 165%, respectively, while it was 412% for the BS. Moreover, the pilot stage's pH monitoring revealed that the electrodeposited Cu2O lowered the concentration of hydronium between 7 to 81 times compared to the BS. Experiments indicated that slight changes in the amount of electrodeposited Cu2O lead to significant changes in samples' ability to hinder bacterial growth and microbial-induced corrosion.
