Bio-Treatment of an Acidic Industrial Wastewater: Tana Explosive Factory

Abstract

ABSTRACT-Tana is one of the Sudanese Military industries. Manufacturing different types of chemical i.e. (TNT, DNT, and MNT). The pH of the acidic wastewater is 1.7 was mixed together with 10% sodium hydroxide lye and neutralized under agitation in neutralizing tank. After neutralization the pH of water reached the value of 6.In this study anew bio treatment is applied to treat acidic wastewater by using moringa oleifera leaves after grinding and mixing in a tank the result indicated that significant increase in pH from1.7 to5.8 in 3 hours, and with 10%added sodium hydroxide (NaOH) pH value reached 6 that without salt sedimentation and low cost of treatment. The Moringa Oleifera leaves showed good treatment properties especially when used for acidic wastewater of pH value (1.7). Moringa Oleifera leaves can raise pH value to (5.8) in three hours. It is highly recommended that realistic visibility study must be carried out to design and apply the manufacture of the tablets of Moringa.
