The public's health and surface water are adversely affected by the improper disposal of abattoir wastewater. In this study, 40 liters of abattoir effluent were treated for ten (10) weeks using raw, powdered Moringa Oleifera seeds as a coagulant. Using processed Moringa Oleifera seeds in loading quantities of 10, 12, 14, 16, 18 and 20g, a completely randomized design was used for the treatment. There was also a control (abattoir effluent not treated with Moringa Oleifera). Before and after treatment, the physical and chemical characteristics of abattoir wastewater were examined. The results demonstrated that the treatments significantly lowered the turbidity value, which fell from 15.40 to 7.63 mg/l for a 16g dosage in week 7. For the 20g treatment in the first week, total alkalinity decreased from 216.67 mg/l to the lowest value of 63.67 mg/l. Just the first week after starting to take 14g of Moringa Oleifera lowered total hardness from 116.33 to 78.40 mg/l and conductivity from 1395.7 to 520 mg/l. From weeks two to six, BOD was discovered to be nil. For the 14g treatment, the Calcium value decreased from 31.47 in the first week to 6.23 mg/l in the fifth week. The results generally demonstrated that 16g/500ml of Moringa oleifera was capable of treating abattoir effluent, confirming its capacity to coagulate for the treatment of such waste. The study's extract doses had no effect on the color or smell of the treated wastewater.

Abstract

The public's health and surface water are adversely affected by the improper disposal of abattoir wastewater. In this study, 40 liters of abattoir effluent were treated for ten (10) weeks using raw, powdered Moringa Oleifera seeds as a coagulant. Using processed Moringa Oleifera seeds in loading quantities of 10, 12, 14, 16, 18 and 20g, a completely randomized design was used for the treatment. There was also a control (abattoir effluent not treated with Moringa Oleifera). Before and after treatment, the physical and chemical characteristics of abattoir wastewater were examined. The results demonstrated that the treatments significantly lowered the turbidity value, which fell from 15.40 to 7.63 mg/l for a 16g dosage in week 7. For the 20g treatment in the first week, total alkalinity decreased from 216.67 mg/l to the lowest value of 63.67 mg/l. Just the first week after starting to take 14g of Moringa Oleifera lowered total hardness from 116.33 to 78.40 mg/l and conductivity from 1395.7 to 520 mg/l. From weeks two to six, BOD was discovered to be nil. For the 14g treatment, the Calcium value decreased from 31.47 in the first week to 6.23 mg/l in the fifth week. The results generally demonstrated that 16g/500ml of Moringa oleifera was capable of treating abattoir effluent, confirming its capacity to coagulate for the treatment of such waste. The study's extract doses had no effect on the color or smell of the treated wastewater.
