Abstract
Effectiveness of using Moringa oleifera seed for the treatment of abattoir wastewater was studied for the period
of five (5) weeks. Completely randomized design with loading dosages of 10, 12, and 14g of processed Moringa
seed was used in the treatment. A control (wastewater from abattoir with no Moringa oleifera treatment) was
also included. Physical and chemical properties of abattoir wastewater were investigated before and after
treatment. The turbidity value was reduced drastically for the treatments from 16.43 mg/l to 11.20 mg/l for 20g
treatment particularly in week 5. Total hardness was reduced from 216.67 mg/l to the lowest value at 137.67
mg/l for 10g treatment in the 5th week. Total alkalinity was reduced from 141.3 mg/l to 66 mg/l for the
treatments, conductivity was reduced from 1395.7 mg/l to 670 mg/l for 14g treatments just within the first
week. The dissolved oxygen was reduced from 6.7 mg/l to zero for the treatments while the BOD was reduced
from 4.33 mg/l to zero. The Calcium value was reduced from 30.53 mg/l to 9.40 mg/l for 18g treatment in the
5th week. The results generally showed that the higher the quantity of Moringa oleifera seed applied to the
wastewater as week passed by, the better the wastewater treatment.
