Utilization of Moringa Oleifera for sedimentation and clarification of Leather Soaking Solution

Abstract

Moringa Oleifera. Lam belongs to Moringaceae family and it is well adapted to and a semiarid condition, in Sudan research information about this plant is rare. The Moringa seeds harvested from Elsamrab farm, the Using Moringa oleifera seeds after oil extraction as natural coagulant for tannery effluent treatment. Tannery wastewater is one of the most . pollution sources so considering to wastewater treatment is too important Awareness of environmental problems has increased considerably and during recent years protecting environment has become a global issue. The peak time of collection is during the Muslim Festival of animal XIsacrifice, the Eid-ul-Adha. This dissertation concerns the study of the treatment of Tannery wastewater (soaking solution), using dry Seed of M. Oleifera. The objective of this study was to evaluate the suitability and develop a treatment system that can effectively reduce the concentration . of pollutants in tannery wastewater (TWW) to acceptable levels Wastewater treatment plants management is an important issue in the water and wastewater industry; so proper design and operation of . wastewater treatment plant is necessary Moringa oleifera Lam (MO) is a pan tropical; whose seeds contain high quality edible oil in this study about 28.5% by weight, moisture and ash contents were 1.8%, and 3.6%, respectively. Materials and Methods Various doses of Moringa seed powder viz. 4, 5 and 6 mg were taken; Parameters of quality of the wastewaters (soaking water) were measured before and after the treatment to evaluate the removal efficiency on the major pollutants of concern in wastewater treatment, such pH, Turbidity, TSS, BOD, and COD were obtained. Untreated wastewater was used, collected before entering the treatment plants of tannery, Seeds were removed from the pod and crushed. 6 liters of wastewater from the tannery (Elnasr). One control and three treatments were used. One-way ANOVA was performed on experimental data to evaluate the statistical significance; the data obtained were statistically . analyzed by the SPSS software The results indicate a significant (p<0.05) All parameters were reduced with increasing dose of seed powder, This study has shown that the MO seeds are highly effective in the treatment of Tannery wastewater, and provide useful information for tannery wastewater treatment, The best results were obtained, The results demonstrated that the tannery effluent had high concentrations of TSS, COD, BOD, PH, and turbidity , percentage removal efficiency for turbidity72.56%, TSS58.86%, XIICOD60% 27.94% PH, and 38.03%BOD All parameters were high, emphasizing the need of secondary treatment for the tannery effluent. Treated water left to settle for one hour. Treatment of Tannery wastewater Samples were higher than the WHO guideline values. But the results . were satisfactory In conclusion MO was available natural coagulants, suitable, easier and environment friendly options for Tannery waste water treatment, moringa has potential to be commercialized in wastewater treatment because it is safe and have many advantages. The data demonstrated that the M. oleifera coagulant was efficient in the treatment of Tannery waste water (TWW), We conclude that the MO has the potential to be used in the Tannery wastewater treatment in an efficient way. Very good complement to Moringa water treatment in developing countries. Finding of this research lend support to earlier works recommending the use of Moringa for wastewater treatment. In this study Output of the waste water . treatment does not comply with Environmental standards and regulations . Any treatment processes have own its advantages and disadvantage
