“…As for the conductivity found after coagulation, it rises significantly since the initial value is between the range of 504-564 μs/cm and after the three types of coagulants it doubles, this is reaffirmed with the one t-test analysis, since it was found that the three coagulants present a significant difference with the initial state (See Table 4). This growth can be attributed to two fundamental aspects, firstly to the addition of NaCl which is used to synthesize the coagulant, and secondly, the MO seeds contain many minerals and inorganic compounds, which dissolve in the water [52]. Similarly, these values are consistent with those found by Kwabena Ntibrey et al [38] where growth in conductivity magnitudes is observed.…”

The scarcity of water has become a growing problem worldwide. The search for new sources has therefore intensified, and one of these sources is greywater. The objective of this article is to evaluate the effectiveness of three different coagulants obtained from Moringa oleiferaseed (seed husk, ground seed, and degreased) in synthetic greywater. The methodology is planned in stages; in the first stage, these seeds were selected, unsheathed, and dried in the sun for 24 hours, and the coagulant was synthesized by a 1 M NaCl solution. In the second stage, the synthetic greywater was prepared in a laboratory and included personal cleaning products and additional chemical components. Finally, a statistical test was employed to evaluate the removal of turbidity and the incidence and behavior of the turbidity, pH, alkalinity, and dissolved oxygen over seven periods and the type of coagulant. It was found that the coagulant degreased obtained the highest percentage of removal (85%) and the coagulant from seed husk had the lowest efficiency with 75%. On the other hand, it was found that parameters such as pH and dissolved oxygen depend on the type of coagulant, while conductivity and alkalinity do not depend on time or the type of coagulant.

“…The observed result shows that pH increase with increasing concentrations of the MoringaOleifera seed coagulant. It was reported that the action of Moringa Oleifera seedas a coagulant lies in the presence of water soluble cationic proteins in the seeds [ 23 ]. This suggests that in water, the basic amino acids present in the protein of Moringa Oleifera seed would accept a proton from water resulting in the release of a hydroxyl group making the solution basic.…”

“…It is in this sense that studies have revealed the capacity of Moringa oleifera seeds for the treatment of raw water as a biocoagulant [39][40][41][42][43]. It has been proven that Moringa oleifera seeds are among the best plant coagulants discovered to date, whose effectiveness is comparable to certain mineral coagulants, such as aluminum sulfate [40,41].…”

The consumption of unsafe water in rural areas is a real public health problem in developing countries. This situation mainly affects children under five years of age and causes several deaths and many cases of malnutrition every year. The objective of this study was to evaluate and optimize the capacity of four local plant extracts in the potabilization of unsafe water. Thus, Moringa oleifera and Boscia senegalensis seeds, or Aloe vera and Opuntia ficus-indica mucilages were prepared in a solution and applied during a jar test as biocoagulants and bioflocculants on three raw water samples of 82.3 NTU, 549.8 NTU and 796.9 NTU. After treatment results showed that 0.9 g/L of Moringa biocoagulant or 1 g/L of Boscia biocoagulant applied with 0.4 mL of Aloe vera bioflocculant or 0.6 mL of Opuntia ficus-indica bioflocculant reduced the turbidity of each water sample to values less than 5 NTU after only 15 min of decanting. Moreover, the sanitary quality of the water treated by these different extracts showed a perfect conformity of the physicochemical and microbiological parameters with the standards of acceptability in drinking water decreed by the World Health Organization. Thus, the application of these local plant extracts has made it possible to considerably improve the quality of unsafe water in record time. Their popularization could be an alternative in the fight against malnutrition related to the consumption of unsafe water, especially in rural areas.
