Mechanisms and Strategies of Advanced Oxidation Processes for Membrane Fouling Control in MBRs: Membrane-Foulant Removal versus Mixed-Liquor Improvement

“…Furthermore, it is also categorized into removable, irremovable, and irreversible fouling based on the attachment strength of the foulant to the membranes. Organic fouling primarily involves the deposition of soluble extracellular polymeric substances (EPS) and soluble microbial products (SMP) secreted by microorganisms, and the adhesion of dissolved and colloidal components from the influent water onto the membrane surface. , Inorganic fouling, often regarded as “mineral scale”, refers to the chemical precipitation of inorganic compounds (e.g., Ca 2+ , Mg 2+ , Fe 3+ , Al 3+ , SO 4 2– , CO 3 2– , and PO 4 3– ) as well as the biological precipitation of inorganic–organic complexes due to crystallization and particulate fouling . Biofouling, regarded as the most critical fouling mechanism in MBRs, occurs concurrently with organic and inorganic fouling.…”

A Machine Learning-Based Decision Support System for Predicting and Repairing Cracks in Undisturbed Loess Using Microbial Mineralization and the Internet of Things

“…Recent years have seen a significant increase in interest across several sectors in the application of learning techniques to extract ground object information, such as soil cracks, from remote sensing high-resolution images. The mechanisms, materials, and technical qualities related to each application of MICP, as well as their different engineering applications, have all been covered in-depth by Yuze et al [9]. Furthermore, Kuan et al [10] have also discussed an addressed the principles of MICP technology as it examines the viability of MICP in several industries including geotechnical, geological, and environmental engineering.…”

“…This process has a wide range of engineering applications, including soil stabilization, groundwater remediation, and construction. From an engineering point of view, various applications of the MICP technology include (i) soil stabilization-the process's microbes generate calcium carbonate, a binding substance that helps to stabilize the soil; (ii) construction -calcium carbonate can precipitate when bacteria are added to the concrete mixture, filling up any gaps and enhancing the overall strength of the concrete [9]. In addition, MICP may also be used for repairing infrastructure in the context of bridges and tunnels, as well as other existing infrastructure.…”

Unlocking the Potential of Microbially Induced Calcium Carbonate Precipitation (MICP) for Hydrological Applications: A Review of Opportunities, Challenges, and Environmental Considerations

“…The main mechanism that relates to this group of applications (Figure 2-remediation) is the solidification of contaminants. This can be succeeded via the increase in the pH (typically achieved by the release of ammonia ions) to promote (i) heavy metal precipitation, (ii) biosorption, and either (iii) coprecipitation of heavy metals with Ca 2+ or (iv) copre cip itation with carbonate (CO 3 2− ) crystals formation [23]. The four pathways might coexist.…”

“…Moreover, MICP provides a low-cost and eco-friendly method for heavy metal remediation through bioimmobilization [40]. In terms of solidifying heavy metalcontaminated soils, MICP contributes to better strength improvement while maintaining better hydraulic conductivity and higher durability, and it rarely damages the original soil structure during grouting, making it more environmentally friendly compared to other agglutinate binders [23,48].…”
