Performance evaluation of Moringa oleifera seeds aqueous extract for removing Microcystis aeruginosa and microcystins from municipal treated-water
Introduction: Toxic microcystins (MCs) produced by cyanoprokaryotes -particularly by the cosmopolitan cyanobacterium Microcystis aeruginosa- pose adverse effects on aquatic organisms and their ecosystem and may also cause serious impacts on human health. These harmful monocyclic heptapeptides are...

Introduction: Toxic microcystins (MCs) produced by cyanoprokaryotes -particularly
by the cosmopolitan cyanobacterium Microcystis aeruginosa- pose adverse effects
on aquatic organisms and their ecosystem and may also cause serious impacts on
human health. These harmful monocyclic heptapeptides are the most prevalent
cyanotoxins reported in freshwaters and must be eliminated for avoiding MCs release
in receiving water bodies. Hence, this work aimed to test the efficacy of Moringa
oleifera seeds water-based extract (MO) as a natural coagulant for removing
cyanobacteria (especially M. aeruginosa), microalgae, and its associated MCs from
pre-treated municipal wastewaters.
Methodology: Four different MO coagulant doses (25, 50, 75 and 100 mg L−1
) were
investigated for cyanobacteria and microalgae removal by conventional coagulation
assays and morphology-based taxonomy studies. Additionally, water turbidity and
chlorophyll a (Chl a) content were also determined. Further, the presence and
concentration of MCs soluble in water, remaining in the particulate fraction, and
flocculated within the residual sludge were assessed using high-performance liquid
chromatography coupled with diode array detection (HPLC-DAD)... |
