“…The circulating water quality parameters also affect the effect of electromagnetic scale inhibition to a certain extent, which mainly includes the PH value of the solution and the concentration of scaling ions. The definition of pH value is the negative logarithm of hydrogen ion concentration in the solution, as shown in equation (5).…”

“…It has the advantages of high efficiency, quick effect and good scale inhibition effect, but the agent cost is high, the environmental protection performance is poor, it is easy to produce secondary pollution and equipment corrosion, and the direct discharge is harmful to the human body and the aquatic environment [4]. The physical scale inhibition method mainly includes high voltage electrostatic treatment, ultrasonic treatment [5] and electromagnetic field treatment [6]. Due to its convenient use and low cost, it has broad research and development prospects and application markets [7].As a key technology for controlling scaling, electromagnetic scale inhibition technology has been in use for over a century and has been widely applied in industry and the market, with continuous improvement.…”

Water treatment is an important means to solve the global water resource shortage problem and ensure human health and economic development. Most existing water treatment technologies have problems such as high energy consumption, high cost, and poor anti pollution performance. Electromagnetic water treatment technology has the advantages of good treatment efficiency, low energy consumption, and environmental protection, and is currently one of the popular new water treatment technologies. This article first elaborates on the scale inhibition mechanism of electromagnetic fields from two aspects: the impact of electromagnetic fields on calcium carbonate crystals and calcium carbonate solutions. Currently, there is controversy in the academic community about the scale inhibition mechanism of electromagnetic fields. This article further lists and compares the experimental methods and conclusions of electromagnetic field scale inhibition, and summarizes and summarizes the scale inhibition mechanism. Secondly, the core components of the electromagnetic scale inhibition device (signal generation device, processing chamber) were elaborated in detail. Finally, a comprehensive analysis was conducted on the factors that affect the efficiency of electromagnetic field scale inhibition, and it was concluded that combining electromagnetic scale inhibition technology with other scale inhibition technologies would have better results.

“…Corrosion reaction on metal can be controlled by using corrosion-resistance material [10,11], coating/painting [12][13][14], and corrosion inhibitors [15][16][17]. Meanwhile, scaling can be solved physically, by the ultrasonic wave and magnetic field, or chemically, by pickling, acidification, and scale inhibitors [18][19][20]. Corrosion (CI) and scale inhibitors (SI) were reported as costeffective and efficient techniques for solving those problems.…”

Corrosion and scale formation are crucial issues in the petroleum industry. They can inflict metal or other materials breakdown, leading to environmental pollution. Applying scale and corrosion inhibitors is a cost-effective and efficient way of controlling corrosion and scale formation in a fluid system. Much research has been conducted to obtain cheap and safe corrosion or scale inhibitors. Modified polysuccinimides (PSI) are among the organic compounds reported as effective and environmentally friendly corrosion as well as scale inhibitors. The use of various novel green corrosion and scale inhibitors from modified PSI for controlling corrosion reactions or scale formation has not been extensively reviewed. Hence, this review highlights recent studies on preparing PSI/OSI, modifying PSI, and analyzing their performance as corrosion and scale inhibitors. Adsorption study, biodegradation performance, computational quantum study, limitations, and prospects of the inhibitors are also discussed. Therefore, i this work provides an overview of novel modified PSI as effective and safe corrosion or scale inhibitors in different media, for various metals, and on a different scale.

“…These techniques cannot present an exact picture of cavitation activity distribution because of expensive instruments [31]. Several researchers used COMSOL at the rst stage of their research to obtain optimal parameters for their experimental studies [9,17,29,[31][32][33]. For example, Sutkar et al [31] used COMSOL to predict the cavitational activity by solving the wave equation in two different geometries of sonochemical reactors.…”

Introducing innovative and environmentally friendly fouling removal methods for water-filled pipelines is essential nowadays to increase pipelines' safety and productivity and eliminate the limitations of traditional descaling methods. In this paper, we investigate the capability of high-power ultrasonic waves and cavitation phenomenon as an influential online fouling removal tool to remove the build-up fouling with a thickness of 1 mm on the inner surface of 4-inch low-carbon stainless steel pipes filled with water. First, we developed a FEM simulation to investigate the effect of ultrasonic power on the acoustic pressure at different distances from the transducer attached point on the pipe using Comsol Multiphysics. After that, we conducted an experimental and statistical investigation to validate our result from FEM analysis using a transducer set and PZT-4 piezoelectric attached to the pipes' outer surface. The results showed that increasing the transducer's electrical power would raise the fluid's acoustic pressure. Furthermore, we indicate that increasing the electrical power to 400 W results in a higher fouling removal rate in the pipe.
