“…During decades, many researchers have investigated the scale deposits from natural, industrial, or synthetic waters [9][10][11][12], to hinder or control scaling process. The most common method that was investigated to avoid scale formation was the addition of chemical substances to the hard waters, that are known as chemical inhibitors [13][14][15][16].…”

In this study, agricultural waste was utilized as new bio-inhibitors to prevent scale formation in hard waters. Aqueous extracts of strawberry and tomato leaves were utilized for reducing the scale deposits formed on metallic surfaces by Bounouara ground hard water, which supplies Constantine city in Algeria. Anti-scaling properties were evaluated by chronoamperometry and impedancemetry techniques. The effect of temperature and concentration on the efficiency of the bio-inhibitors was assessed. The results showed that the anti-scaling effect of strawberry leaf extracts started at the very low concentration of 1 ppm, with 31% efficiency, reaching complete scaling inhibition at 15 ppm (20ºC), whereas the inhibitory effect of tomato leaf extracts was noticed at 2.5 ppm, with 36% efficiency, and total inhibition at 20 ppm (20ºC). The efficiency of strawberry and tomato leaf extracts at 40∘C was also confirmed, although total inhibition was attained at a higher concentration.

In order to reduce the water deficit in the Moroccan Souss-Massa region, the region's master development plan recommends the use of unconventional resources. The reuse of treated wastewater represents a significant contribution to reduce water deficiency, and it is becoming unavoidable today. The treated wastewater is currently used to water the green space of Agadir's Golf. This water is conveyed, from the L'Mzar wastewater treatment plant to the Golf Ocean, in 60 cm diameter transport pipes over a length of 3 km. During one month of flow of treated wastewater through these pipes, the phenomenon of scaling of the latter is observed and has led to the formation of solid and adherent deposits on the sidewalls of these pipes and on the golf sprinklers (Due to high values of HCO 3 − ̴ 712 °F, Ca 2+ ̴ 288 °F and Mg 2+ ̴ 13 °F). Consequently, this causes several technical, economic and environmental problems. The objective of this work is the study of the scaling phenomenon observed in the purified wastewater transport pipes of L'Mzar treatment plant. Thus, in the first step, the purified wastewater was collected and analyzed. In this study, we used the representations of Piper and Schoeller-Berkaloff of purified wastewater of L'Mzar treatment plant in the second step. The predominant facies are calcium and magnesium hyperchloride and hypersulfate calcic with a slight tendency toward sodium hyperchloride. Then we presented, in a last step, the results of thermodynamic predictions of scaling phenomenon of treated water from the treatment plant of L'Mzar using the method of Legrand-Poirier-Leroy (LPL) with respect to the calco-carbonic equilibrium and to conclude that this water is a calcifying type (the ionic balance is less than 5% for all samples, and the supersaturation coefficient is largely exceeded 1 (β > 1)). The highlighting of new scale inhibitors to prevent the formation of scale in the pipelines of purified water transport pipes will also be discussed.

[21] The aim of this study is to assess the feasibility of removing ammonium from groundwater using ED with AXE membranes as anion exchange membranes (AEMs) and CMX membranes as cation exchange membranes (CEMs). The treated water is intended for human consumption, with the aim of mitigating the loss of water resources compromised by high levels of pollution.…”

In this work, we investigated the feasibility of ammonium removal by electrodialysis (ED), a well‐known electro‐membrane process, based on the selective migration of anions and cations through anion exchange membranes (AEMs) and cation exchange membranes (CEMs). ED experiments are performed using a laboratory pilot. The ion exchange membranes (IEMs) pair used is AXE/CMX, AXE as an AEMs and CMX as a CEMs. The first tests are performed with real groundwater solutions from Kenitra city (Morocco), spiked with an initial concentration of 3 mg/L NH4Cl. The results gave a specific demineralization (SD) to NH4+ ions of 84.60 %; for a demineralization rate (DR) of 80 % and a time of 60 min. The multivariate principal component analysis (PCA) presents a total inertia of 99.23 %, the majority of the variables of which are positively correlated on the C1 axis with a variance of 95.5 % than that of C2 of 3.78 %. The quality of the diluted water determined by the Legrand‐Poirier method showed that the water was aggressive and that the addition of 4.54 mg/L Ca2+ was necessary to balance the water and make it fit for human consumption.
