“…When extracting, purifying, storing and transporting organic coagulants, many factors affect the performance and effectiveness of these materials, including reaction temperature, pH, maceration time, storage time, microbial effects; for example, storage temperature must be low to avoid degradation of the various active compounds responsible for coagulation, such as tannins, polyphenols, starch, proteins and polysaccharides [155].…”

This review describes the mechanisms of natural coagulants. It provides a good understanding of the two key processes of coagulation-flocculation: adsorption and charge neutralization, as well as adsorption and bridging. Various factors have influence the coagulation/flocculation process, including the effect of pH, coagulant dosage, coagulant type, temperature, initial turbidity, coagulation speed, flocculation speed, coagulation and flocculation time, settling time, colloidal particles, zeta potential, the effects of humic acids, and extraction density are explained. The bio-coagulants derived from plants are outlined. The impact of organic coagulants on water quality, focusing on their effects on the physicochemical parameters of water, heavy metals removal, and bacteriological water quality, is examined. The methods of extraction and purification of plant-based coagulants, highlighting techniques such as solvent extraction and ultrasonic extraction, are discussed. It also examines the parameters that influence these processes. The methods and principles of purification of coagulating agents, including dialysis, freeze-drying, ion exchange, electrophoresis, filtration, and centrifugation, are listed. Finally, it evaluates the sustainability of natural coagulants, focusing on the environmental, technical, and economic aspects of their use. At the end of this review, the readers should have a comprehensive understanding of the mechanisms, selection, extraction, purification, and sustainability of plant-based natural coagulants in water treatment.

“…The potential of various tree parts from Jatropha curcas to efficiently treat wastewater effluents has been well documented in a few works. For example, biocoagulant extracted from J. curcas press cakes and seeds was found to be effective in reducing turbidity in kaolin wastewater [35], palm oil mill effluent (POME) [36], and pharmaceutical wastewater [37]. J. curcas bark, seed peel, and endosperm seed also showed excellent separation performance to remove divalent cadmium ions from wastewater [38].…”

This study aimed to optimize the removal of Cu(II) ions from an aqueous solution using a Jatropha oil bio-based membrane blended with 0.50 wt% graphene oxide (JPU/GO 0.50 wt%) using a central composite model (CCD) design using response surface methodology. The input factors were the feed concentration (60–140) ppm, pressure (1.5–2.5) bar, and solution pH value (3–5). An optimum Cu(II) ions removal of 87% was predicted at 116 ppm feed concentration, 1.5 bar pressure, and pH 3.7, while the validated experimental result recorded 80% Cu(II) ions removal, with 95% of prediction intervals. A statistically non-significant term was removed from the analysis by the backward elimination method to improve the model’s accuracy. Using the reduction method, the predicted R2 value was increased from −0.16 (−16%) to 0.88 (88%), suggesting that the reduced model had a good predictive ability. The quadratic regression model was significant (R2 = 0.98) for the optimization prediction. Therefore, the results from the reduction model implied acceptable membrane performance, offering a better process optimization for Cu(II) ions removal.

“…Amid its benefits, Jatropha curcas oil has been explored as a replacement for fossil fuels in minimizing greenhouse gas emissions [8], making candles, soaps, cosmetics [9], and also surface coatings [10]. In addition, the seed extracts and press cake were utilized in water and wastewater treatment [11][12][13][14]. In recent years, Jatropha oil-derived materials have been exploited to produce biodegradable film for packaging, insulation, and furniture [15][16][17].…”

More recent attention has been focused on the utilization of Jatropha curcas in the field of water treatment. The potential of Jatropha oil in the synthesis of membrane for water filtration had been explored, its performance compared to the addition of graphene oxide (GO) in the polymer matrix. Jatropha oil was modified in a two-step method to produce Jatropha oil-based polyol (JOL) and was blended with hexamethylene diisocyanate (HDI) to produce Jatropha polyurethane membrane (JPU). JPU was synthesized in different conditions to obtain the optimized membrane and was blended with different GO loading to form Jatropha/graphene oxide composite membrane (JPU/GO) for performance improvement. The synthesized pristine JPU and JPU/GO were evaluated and the materials were analyzed using fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), contact angle, water flux, and field emission scanning electron microscopy (FESEM). Results showed that the ratio of HDI to JOL for optimized JPU was obtained at 5:5 (v/v) with the cross-linking temperature at 90 °C and curing temperature at 150 °C. As GO was added into JPU, several changes were observed. The glass transition temperature (Tg) and onset temperature (To) increased from 58 °C to 69 °C and from 170 °C to 202 °C, respectively. The contact angle, however, decreased from 88.8° to 52.1° while the water flux improved from 223.33 L/m2·h to 523.33 L/m2·h, and the pore distribution in JPU/GO became more orderly. Filtration of copper ions using the synthesized membrane was performed to give rejection percentages between 33.51% and 71.60%. The results indicated that GO had a significant impact on JPU. Taken together, these results have suggested that JPU/GO has the potential for use in water filtration.
