Comparative Studies of Wastewater Treatment Using Moringa oleifera, Hypochlorite and Alum for Irrigation
The use of treated wastewater for irrigation purpose is becoming increasingly popular globally especially in arid and semi-arid regions where freshwater is scarce. In this paper, abattoir wastewater in Maiduguri was treated with Moringa oleifera (MO), Hypochlorite and Alum at 0 (Control), 0.10, 0.20, 0.30 and 0.40 g/L Moringa Seed Solution Concentration (MSSC) using FAO irrigation water quality guideline as benchmark and cost comparisons made for the three reagents used. Results from coliform count and turbidity plots showed that higher MSSC resulted to higher reduction in coliform count and turbidity values and vice versa. Also, it was found that MO is cheaper followed by Alum and Hypochlorite being costlier. Therefore, it is hereby recommended that MO seed solution be used as a water treatment reagent for irrigation.
