This
research was carried out to evaluate the coagulating effects of Moringa
oleifera (Linnaeus) seed
powder on wastewater at lower and higher concentration levels using Jar test. 10,
20, 30 and 40 ml of Moringa seed powder-prepared stock solution were
used as lower concentration level, while 70, 80 and 90 ml were used as higher concentration
level; and results compared. A control experiment was also set up. The
pH, Temperature, Total Dissolved Solids, Conductivity and Total Suspended Solids
were measured at 24 h post-treatment. Gas
Chromatography–Mass Spectrometry was used to reveal chemical
components in the ethanolic
extract of M. oleifera seed powder. The optimum concentrations
for Moringa coagulant at lower and
higher concentration levels were 40 and 70 ml respectively. It was observed
that 40 ml reduced the Total Suspended Solids of the wastewater from 1240 mg/l
to 400 mg/l after 24 h settling interval with removal efficiency of 67.7%. Also,
70 ml reduced the Total Suspended Solids from 1240 mg/l to 360 mg/L after 24 h
settling time with removal efficiency of 70.9%. Total Dissolved Solids and Conductivity
gradually increased for both concentration levels with increasing concentrations, but were within the World
Health Organization recommended standard for drinking water. As observed, both concentration
levels did not influence (increase) the temperature and pH of wastewater. The pH
values of the treated-wastewater at both concentration levels ranged between
6.7 and 7.8. Findings from this research showed that M. oleifera, a
natural coagulant, has greater coagulating efficiency at higher concentration
levels.
