“…A number of scale inhibitors are commercially available and new formulations are continuously being developed for testing in a variety of scaling systems (Choi et al ., 2002; Amjad and Zuhl, 2007; Abdel‐Gaber et al ., 2008; 2011; Xu and Wang, 2018; Korchef and Touaibi, 2020; Veisi et al ., 2019). In particular, plant extracts are being used as antiscalants, since they are intrinsically environmentally friendly (Ji et al ., 2017; Menzri et al ., 2017; Suharso et al ., 2017; Nabi et al ., 2018; Hao et al ., 2019).…”

The formation of CaCO 3 of groundwater has important implications in the industry. Many conventional scale inhibitors are considered environmentally unfriendly. In this study, we investigate the effect of aqueous extract of Paronychia arabica (PA) as new green antiscalant agents on the precipitation of CaCO 3 in an arid desert region. The antiscaling properties of these extracts towards CaCO3 formation were tested using chronoamperometry (CA), electrochemical impedance spectroscopy (EIS) and Fast Controlled Precipitation methods. Electrochemical and chemical analysis of Mkhadma groundwater shows a high calcium concentration and the deposit is a pure calcite. The nucleation and formation time were identified. At 32°C, a complete scaling inhibition was obtained using a concentration of 150 mg/L of green extract. The scale inhibitor effect was analysed by an optical microscopic examination.
