Abstract

A preliminary investigation was carried out for the feasibility of using blends of Moringa Oleifera Seed
Extract (MOSE) and Pumpkin Seed Extract (PSE) to treat surface water. The two seed extracts were mixed
in proportions ranging from 100 % Moringa Oleifera (MO) and 0 % Pumpkin (PPK) to 0 % MO and 100
% PPK. 5.0, 5.5, 6.0, 6.5 and 7.0 ml of the blends were used to treat 500 ml of raw water on a jar test
apparatus. The contents of the jar were stirred rapidly for 5 min at 100 rpm and slowly stirred for 15 min
at 50 rpm. The water was then allowed to settle, filtered and analysed for; turbidity, hardness, pH,
biological oxygen demand (BOD), chemical oxygen demand (COD) and bacterial load (E-coli.). From the
results obtained, it showed that the 100 % MO had maximum reduction in turbidity and bacterial load of
97 % and 67 %, whereas, 100 % PPK had maximum reduction in turbidity and bacterial load of 89 % and
100 % respectively. Furthermore, the results for the blends showed that blends with more concentrations of
Moringa Oleifera had more effect on the reduction of; turbidity by 98 %, hardness by 78 %, and COD by
82 %. On the other hand, blends with more concentrations of pumpkin had more effect on the reduction of;
BOD by 43 %, COD by 82 % and bacterial load by 100 %. However, analyses on the treated water showed
that Moringa Oleifera and Pumpkin did not significantly affect the pH (1.5 – 5.8 %) after treatment.
Certainly, the results obtained in this research are in agreement with the standards by Standards
Organisation of Nigeria (SON) and World Health Organisation (WHO). Therefore, the study showed the
possibility of blending Moringa Oleifera and Pumpkin seeds cake extracts as a viable and indigenous
pretreatment approach in raw water treatment.
