“…Commonly, homegrown wastewater is made out of numerous pathogens and non-pathogenic microorganisms, natural/inorganic synthetics, suspended, broken up mixes and so forth [14]. Acidic and sulfide exposure of pipelines caused by microbial activities is the major reason behind biological and chemical corrosion [15]. Corrosion is generally termed as an unwanted characteristic cycle bringing about the slow demolition of materials including metals, concrete, etc.…”

Adverse effects of wastewater on the hygiene of human and circumstances is a major issue in society. Appropriate refining systems with high efficiency is required to treat the wastewater. Sewage treatment plant plays a major and important role in conserving incredible nature of the environment. Microbiologically Induced Corrosion (MIC) is an important phenomenon in sewage structures which causes the deterioration of infrastructures. Huge capital has been spent and efforts have been made on wastewater treatment infrastructure to increase operating efficiency and reliability of compliance. The investments in reimbursement and maintenance of sewer structures upsurge with an increase in the rate of MIC. The focus of this review is to describe MIC in sewer structure and the factors influencing the corrosion such as the generation of Sulfuric acid (H2SO4), Relative Humidity (RH), pH of the concrete structure and temperature. Modern developments in the design of Fiber Optical Sensors (FOSs) for observing the parameters including pH, Hydrogen Sulfide (H2S), RH and temperature will be discussed.

“…The phenomenon of bacterial production of H 2 SO 4 from H 2 S followed by corrosion of steel and concrete elements is well documented in sewages and wastewater treatment facilities, where H 2 S is the previous result of bacterial activity on the waste (e.g., [31]). The process of biogenic sulphuric acid corrosion is driven by a succession of different bacterial species requiring different environmental pH [32].…”

“…and Thiomonas spp., which generate sulphuric acid and polythionic acids, lowering the pH to 3.5-5.0. As the pH decreases, other bacteria take over, in successive steps, which are capable of living at progressively lower pH, such as Acidithiobacillus thiooxidans, and continue the process of sulphur oxidation and sulphuric acid production from pH 5 to as low as 1-2 [31,33].…”

Phlogopite flakes strewn on the soil of Caldara di Manziana (Italy) display multiple minute perforations. The site is a caldera linked to recent volcanism (90 ka to 0.8 Ma) with present emanations of CO2 (~150 t d−1) and H2S (~2.55 t d−1). Stereomicroscopy and SEM–EDX observation of the phlogopite crystals shows holes and depressions <200 µm to 2 mm across. They are circular, pseudo-hexagonal, or irregular. Within the depressions, there are deposits of phlogopite alteration products consistent with a sulphuric acid attack, showing loss of Mg and K. Some are thin and homogeneous; others are thick, irregular, and chemically heterogeneous, including plates, flakes, tubes of Fe-beidellite or Fe-bearing halloysite, silica, Fe oxides, and gypsum. Areas of phlogopite surface are also altered. Sulphuric acid is produced from the H2S gas by the mediation of sulphur-oxidizing bacteria. Pseudo-hexagonal perforations are interpreted to result from slow acid attack with dissolution controlled by phlogopite crystal symmetry. Some depressions developed surrounding films of pseudo-hexagonal shape, interpreted as jarosite crystallizing radially outwards from the depressions. This style of acid attack is possibly promoted by local high humidity and precipitation that generate long-lived water droplets and films on mineral surfaces where sulphuric acid is active for prolonged times.

“…The literature shows that more than 40% of the total volume of biological injuries is related to the activity of microorganisms -bacteria and fungi [6][7][8]13]. To a greater extent, biodamages of building materials are caused by products of the metabolism of microorganisms [9][10][11]14].These processes are particularly intense in environments of biogenic organic and inorganic acids, which are typical for sewage treatment plants and wastewater treatment plants made of cement concrete [15,16]. The intensity of corrosion processes when exposed to metabolic products is determined by the rate of chemical reactions at the phase contact boundary and the rate of their diffusion into the material structure.…”

Due to the complex and constantly changing global environmental situation, the study of the resistance of mineral binder-based building composites to the effect of the metabolism products of microscopic organisms seems particularly relevant. Taking into account the nature of the effect of bacteria and mycelial fungi on cement stone, a method of evaluating the resistance on the basis of modeling by replacing the real development of colonies of microorganisms with chemically aggressive aqueous solutions of their life products is proposed. It is allowed to study the current processes of phase transformations, as well as changes of operational parameters in the form of regression dependencies.
