“…Tzoti pointed out that the scale retardation mechanism is a threshold effect, a crystal distortion effect, dispersion, and chelation 19 . Mutairi outlined the scale inhibition mechanism as follows: the destruction of the scale activity, changes in the physical interaction between the foulant and the surface, forced scale removal, and fouling potential modification 20 . He stated the mechanism is selective nucleation, makeup adsorption resistance, and change in the crystal surface to enhance agglomeration tendency 21 .…”

This study aims to mitigate CaCO3 scale formation in pipes under influence of vibration and oxalic and formic acid additives. The vibration of the pipes was generated mechanically by an electrical motor and controlled by a computer program. CaCO3 scale was synthesized by CaCl2 and Na2CO3 reagents. The scale deposition was examined at a temperature of 35°C and vibration frequencies of 0.00, 3.00, and 6.00 Hz. The mass of scale deposit was found as 3.3211 g, 3.8358g, and 4.4705 g. Fourier Transform Infra Red spectroscopy analysis proved that the additives successfully diffused into the crystal lattice and retarded carbonate anion formation, which consequently retarded the scale formation. In addition, the use of oxalic acid made the morphology of vaterite-changed. However,the formic acid was added, a new habit of hexagonal thin-plate vaterite-could be observed and a fewer carbonate scale was obtained.

“…The use of antiscalants or chemical inhibitors by means of chelation (Chen and Chan, 2000) dispersion (Wang et al, 2002) and inhibition (Lisitsin et al, 2005;Ketrane et al, 2009;Al-Mutairi et al, 2009;Kukulka and Devgun, 2007) is an effective method to control scaling problems. This chemical method however, is expensive and can change the water chemistry (Macadam and Parsons, 2004;Baker and Judd, 1996;Coetzee et al, 1998).…”

This study studied the synergistic anti-scaling performance of composite scale inhibitor and efficient electromagnetic anti-scaling instrument. And experiments were conducted to investigate the anti-scaling performance of composite scale inhibitor and anti-scaling performance and mechanism of efficient electromagnetic anti-scaling instrument, respectively. The crystallization of CaCO 3 was characterized by Scanning Electron Microscope (SEM) and X-Ray Diffraction (XRD). The experimental results showed that the highest anti-scaling rate of composite scale inhibitor (1#) was 80.68% and highest anti-scaling rate of composite scale inhibitor (2#) was 76.53%, average anti-scaling rate of efficient electromagnetic anti-scaling instrument was 51.46%. Efficient electromagnetic anti-scaling instrument promoted CaCO 3 crystallization process and promoted calcite into aragonite. When efficient electromagnetic anti-scaling instrument worked with composite scale inhibitor, synergistic anti-scaling rate of composite scale inhibitor (1#) had a 15% higher than composite scale inhibitor (1#) and synergistic anti-scaling rate of composite scale inhibitor (2#) had a 20% higher than composite scale inhibitor (2#).
