چکیده (انگلیسی):

Waste effluents samples collected from African textile manufactures ltd (ATM) located in Challawa Kano state, was studied for the effectiveness of using Moring Oleifera lam (Zogale) seed powder in its treatment. The effect of oil extraction (of the seed) and pH – correction of the effluents on the treatment was also studied.It was observed that Moring seed powder can be used as a primarycoagulant beforeor after the moringa oil extraction.The moringa seed exhibit no effect on the pH value of the treated effluents as no significant change on the coagulation property after pH – correction of the effluents was observed. Metals content was determined using AAS method.It was observed that the mean reduction in concentration of the metals in the treated to raw ranged from 49% (Mn), 46% (Cr), 40% (Fe), 33% (Zn), 33% (Ca), 28%(Pb)23% (Mg), 1%(Co), the percentage decrease in turbidities before or after oil extraction ranged between 80% to 93%. Moringa oleifera seed powder can be used effectively in the pretreatment of textile waste effluents before its final discharge into the surface water.
