“…Scale formation in circulating cooling systems poses several hazards, including (1) scale, being a poor conductor, can impede heat transfer during the circulation process, indirectly affecting production efficiency and, in severe cases, may lead to hazardous events like explosions; (2) scale can reduce the flow area in pipes, increasing fluid resistance and thus energy consumption; (3) excessive scale deposition necessitates shutdowns for cleaning, reducing equipment operational time and efficiency [17][18][19][20][21][22]. Hence, addressing scale formation in CCW is urgent, not only for average industrial production and economic benefits but also for conserving water resources and ensuring industrial safety [23,24].…”

In recent years, electrochemical descaling technology has gained widespread attention due to its environmental friendliness and ease of operation. However, its single-pass removal efficiency could be higher, severely limiting its practical application. To overcome the limitations of traditional electrochemical descaling processes, this paper first focuses on the separation efficiency of H+ and OH− in the scale removal process based on numerous recent research papers. It mainly emphasizes how innovative cathode design can enhance the efficiency and stability of electrochemical descaling. Furthermore, this paper explores the coupling of electrochemical processes with different water treatment technologies, such as the combination of electrodeposition with electrocoagulation, filtration crystallization, microfiltration, and electrodialysis, and how these methods synergistically enhance descaling effects. Additionally, this paper discusses potential future directions for electrochemical descaling technology, including innovations in scale expansion, material updates, process optimization, system integration, and automation. Finally, this paper analyzes the practical challenges of electrochemical descaling technology, such as cost, energy consumption, equipment durability, and environmental impact, and proposes solutions. The implementation of these strategies is expected to promote the commercialization of electrochemical descaling technology, making it more aligned with the sustainability requirements of industry and the environment.

“…Calcium carbonate is the most common scale encountered in water systems. To control scale formation, two main preventing processes can be used in industrial plants: chemical and physical methods [3–5] . One of the most efficient methods used to prevent scale formation is the addition of antiscalants in water also called scale inhibitors [6,7] .…”

“…To control scale formation, two main preventing processes can be used in industrial plants: chemical and physical methods. [3][4][5] One of the most efficient methods used to prevent scale formation is the addition of antiscalants in water also called scale inhibitors. [6,7] Nowadays, as new international guidelines for industrial discharges are becoming more stringent in terms of ecology, the use of these antiscaling substances is more limited and physical treatments such as magnetic field (MF) are becoming a well adapted and pertinent possibility.…”

In this study, fast controlled precipitation (FCP) and chronoamperometry (CA) methods were performed to evaluate the influence of the magnetic treatment at 0.70 T, upon the scale formation in synthetic solutions (hardness 25 °F), exposed to a static magnetic field for different exposure times. According to FCP results, homogeneous CaCO 3 precipitation rates in treated solution were lower than those in the absence of the magnetic field. It has been found that the memory effect can last up to 24 h after the magnetic treatment even if it decreases over time. As purpose of comparison, CA method was applied to investigate the influence of the magnetic treatment on heterogeneous CaCO 3 precipitation. The magnetic field effect increased with the increasing exposure time. The obtained scale, characterized by scanning electronic microscopy and Xray diffraction, was formed by a mixture of calcite and aragonite in the presence of magnetic field.
