“…RSM was applied as a statistical and mathematical method which is used mainly to design experiments, reduce the number of planned experiments and assess the relationship between input and output factors (Apostol et al ., 2011; Jung et al ., 2015; Sarrai et al ., 2016; Tassalit et al ., 2016; Watson et al ., 2016; Arhin et al ., 2018; Djerroud et al ., 2018; Dehghani et al ., 2018; Mohammadi et al ., 2018). A Box‐Behnken Design (BBD) with three independent variables was used to investigate the effect of coagulant dose, slow stirring time and slow stirring velocity on the turbidity removal efficiency and residual metal concentration.…”

The purpose of this study is to optimize the operating conditions in batch mode using Box‐Behnken Design (BBD), for the coagulation‐flocculation line sizing prior the sand filter in the pilot scale. Three coagulants were employed to achieve a high turbidity removal with a low concentration of residual metals. The results showed that the best turbidity removal was obtained with FeCl3. Using BBD (15 experiments), the optimal parameters were: coagulant dose = 5.5 mg FeCl3/L, slow stirring time = 33 min and slow stirring velocity = 45 rpm, in these conditions, the turbidity removal reached 94.89% and the residual iron concentration was 0.449 mg/L. Regarding the model fit, the obtained R2 values were 99.67% for turbidity removal and 99.47% for residual iron concentration. The optimum conditions obtained from this study could be scaled up and applied to desalination plants. BBD approach is of great interest because it allows the prediction of the response value without performing experiments.

“…In addition, there are the first publications on this topic in water treatment/water environment-related journals in 2021 and 2022. Hussain and Haydar (Hussain et al, 2021) prepared a novel plant flocculant using Opuntia stricta (Adjeroud et al, 2015(Adjeroud et al, , 2018Djerroud et al, 2018;Adjeroud-Abdellatif et al, 2020). The results showed that the main component in the flocculant was polysaccharide.…”

Plant polysaccharides are rich in physiological activities, which are beneficial for developing new drugs, nutraceuticals and functional foods. Cactus is of interest to researchers in agronomy, medicine and food chemistry because of its long history of medicinal use, its simple growing requirements and biological basis for becoming a green vegetable. This review provides the first summary and analysis of the research history of cactus polysaccharides through a bibliometric approach. Bibliometrics was used to investigate the focus of different stages of development of the topic, with contributions from different countries and institutions. In addition, keyword analysis and keyword clustering were used to understand the different research directions of this topic. The analysis showed that (1) the study of cactus plant polysaccharides is a long-established topic but did not attract much attention in its early stages. (2) In 2018, research on cactus polysaccharides has received more attention than ever before. (3) Mexican institutions and scholars have contributed the most important contributions to this topic. (4) This theme has only formed one complex network of cooperation, mainly composed of Mexican institutions and scholars. (5) Early studies on cactus polysaccharides focused on the detection, extraction and purification of polysaccharide content. (6) The biological activities of plant polysaccharides have gradually become the focus of research in recent years. (7) The biological activity of plant polysaccharides has been verified from in vitro experiments and in vivo experiments with positive results.

“…Cactus flowers, fruits and leaves are consumed as vegetables in different areas of the globe (Kamble et al, 2017). Cactus derivatives like pad juice and cladode mucilage are very effective components for water purification solely or in combination with wastewater treatment processes (Adjeroud et al, 2018(Adjeroud et al, , 2015Djerroud et al, 2018). Some other studies have been performed in Algeria on the extraction and characterization of mucilage from cladodes of O. ficus-indica (Adjeroud-Abdellatif et al, 2020;Adjeroud et al, 2018Adjeroud et al, , 2015Djerroud et al, 2018;Felkai-Haddache et al, 2016;Lefsih et al, 2018).…”

Much attention has been paid to cacti for their distinctive characteristics. The nopal Opuntia ficus-indica and related species are found in arid and semi-arid regions around the world. O. ficus-indica shows considerable variability in response to environmental conditions through variation of areola and spine attributes, among other traits. Therefore, the present study sought to morphologically identify some cactus pear plants in two areas of Algeria (Bejaia and Souk-Ahras) in order to evaluate the cactus pears by optimizing the extraction conditions of the phenolic compounds of the cladode, to evaluate the antioxidant activity of these compounds, to measure the total flavonoid content, and to compare the yields among three Opuntia spp. (O. ficus-indica, O. megacantha and O. amyclae) from the sites within the study regions. These three Opuntia spp. were subjected to extraction of polyphenols using a conventional method, and an ecofriendly process using ultrasound-assisted extraction (UAE) technique. Once the extractions was completed, the total phenolic content and flavonoids of the extracts were characterized. In addition, the antioxidant capacity of the total phenolic compounds (TPC) was determined. The UAE was better than conventional extraction for the recovery of TPC. The use of a solvent mixture (50% water/ethanol, v/v) improved the TPC extraction efficiency. These results show that UAE was a useful tool for the extraction of phytochemicals from cactus pear cladodes. Other factors and conditions that influence the optimization of TPC extraction should also be studied, such as pH, ultrasound frequency as well as ecological factors that could possibly influence extraction efficiency.
