“…This indicates the propensity for MO to form organo-metallic complexes. The potential therefore exists for MO to be employed in the removal of specific metal ions from solution which may include the removal of heavy metals from wastewater discharges [ 15 , 18 ]. Decreased levels of metals may also occur because Moringa amphoteric protein binds to the oppositely charged metal ions and causes them to precipitate [19] .…”

This research evaluated Moringa oleifera seed powder (MOSP) as an antibacterial agent, and a coagulant. In the former, clinical isolates of Salmonella sp ., Staphylococcus aureus ( S. aureus ) and Escherichia coli ( E. coli ) were used, and in the latter, river and stream water were used. Both the isolates and water samples were treated with MOSP at varying final concentrations of 0.001, 0.002, 0.004 and 0.017 g/ml. For the antibacterial assay, a dose of 0.017 g/ml of MOSP was effective on all three isolates with CFU/ml reduction of 99.4, 78.8 and 57.3% on Salmonella sp ., E. coli and S. aureus respectively. An ANOVA confirmed this finding at P <0.05; 0.0014 between the treated and control samples. The water treatment assay also showed a reduction of total hardness, fluoride, phosphate, nitrate, total iron and manganese levels below the water quality standards. The MOSP could serve as a cost-effective product for process integration in raw water treatment systems in rural and urban settings. The study shows bioactivity of the seed powder of Moringa, and provides grounds to isolate the active component for commercialization and usage by the wider population with limited or no access to potable water.

“…Moringa oleifera extracts as well as other natural coagulants are presently in demand because they are less toxic and ecofriendly [183]. Reports have also shown that combined treatment can present better coagulation effect as seen in Alam et al [183] report. There is always a need to carry out test to ascertain the toxicity of plants extracts to be used in water treatment and ensure its effect falls within the WHO guideline values, to be proved effective [60].…”

“…Moringa seeds have been greatly studied for water treatment due to the presence of cationic proteins (dimeric) responsible for their anticoagulant potential [208,209]. Moringa oleifera extracts as well as other natural coagulants are presently in demand because they are less toxic and ecofriendly [183]. Reports have also shown that combined treatment can present better coagulation effect as seen in Alam et al [183] report.…”

Plant active products and emerging interventions in water potabilisation: disinfection and multi-drug resistant pathogen treatment

et al. 2021

Background This review aims at establishing the emerging applications of phytobiotics in water treatment and disinfection. Results Statistical analysis of data obtained revealed that the use of plant product in water treatment needs more research attention. A major observation is that plants possess multifaceted components and can be sustainably developed into products for water treatment. The seed (24.53%), flower (20.75), leaf (16.98%) and fruit (11.32%) biomasses are preferred against bulb (3.77%), resin (1.89%), bark (1.89%) and tuber (1.89%). The observation suggests that novel applications of plant in water treatment need further exploration since vast and broader antimicrobial activities (63.63%) is reported than water treatment application (36.37%). Conclusions This review has revealed the existing knowledge gaps in exploration of plant resources for water treatment and product development. Chemical complexity of some plant extracts, lack of standardisation, slow working rate, poor water solubility, extraction and purification complexities are limitations that need to be overcome for industrial adoption of phytochemicals in water treatment. The field of phytobiotics should engage modern methodologies such as proteomics, genomics, and metabolomics to minimise challenges confronting phytobiotic standardisation. The knowledge disseminated awaits novel application for plant product development in water treatment.

“…The produced material was characterized by an easy-to-control morphology, high thermal stability, small-sized particles, good crystallinity and considerable-size BET surface area. Overall, the antibacterial properties are now being extensively harnessed, mainly for water purification in the presence of E. coli [ 20 ].…”

The In Situ Hydrothermal and Microwave Syntheses of Zinc Oxides for Functional Cement Composites

et al. 2022

This study presents the results of research on cement mortars amended with two zinc oxides obtained by two different methods: hydrothermal ZnO-H and microwave ZnO-M. Our work indicates that, in contrast to spherical ZnO-H, ZnO-M was characterized by a columnar particle habit with a BET surface area of 8 m2/g, which was four times higher than that obtained for hydrothermally obtained zinc oxide. In addition, ZnO-M induced much better antimicrobial resistance, which was also reported in cement mortar with this oxide. Both zinc oxides showed very good photocatalytic properties, as demonstrated by the 4-chlorophenol degradation test. The reaction efficiency was high, reaching the level of 90%. However, zinc oxides significantly delayed the cement binder setting: ZnO-H by 430 min and ZnO-M by 380 min. This in turn affected the increments in compressive strength of the produced mortars. No significant change in compressive strength was observed on the first day of setting, while significant changes in the strengths of mortars with both zinc oxides were observed later after 7 and 28 days of hardening. As of these times, the compressive strengths were about 13–15.5% and 12–13% higher than the corresponding values for the reference mortar, respectively, for ZnO-H and ZnO-M. There were no significant changes in plasticity and flexural strength of mortars amended with both zinc oxides.
