This study investigated the possibility of producing biogas from tannery waste water (liming and deliming liquors) in Al-Amatounj Tannery in Khartoum. The study is based on laboratory analysis and experimental works which have been took place through a pilot scale anaerobic sequencing batch reactor (ASBR), which’s designed for the digestion process for biogas production. Experiments verified that the biogas production rates were mainly affected by operating temperature, pH, and substrate concentration. Two experiments were carried out in the range of temperature 35–40°C. The gas produced was measured by the liquid displacement system. Meanwhile, the highest biogas yields were 72% of CH4 and 28% of CO2. The production of biogas from 20 L tannery waste water with 100 g yeast , 0.0215m3, and the biogas was generated after three days. The results from this research work are considered as providing useful information and operational parameters and that promotion is more successful with efficient anaerobic codigestion.

Physical And Chemical

Tannery waste water contains an enumerous amount of chemicals and a high level of pH, TDS, TSS, BOD, and COD, which gets directly into the natural aquatic environment, thus polluting to the water quality. Because of that important to develop a cost-effective and eco-friendly technology to treat the tannery waste water. Our present research work has been done to investigate the physical and chemical characteristics of tannery waste water and to decrease the value of BOD, pH, and COD by the procedure of bioremediation using microbes. Among the physical and chemical characteristics analyzed BOD, pH and COD were find to be very huge value. Pseudomonas aeruginosa and Bacillus cereus were identified and isolated and utilized in the decrease of BOD, pH, and COD in the tannery waste water. Four different concentrations of untreated tannery waste water (control, 25, 50, 75, and 100%) were prepared. The treatment was carried out for 48 hrs (2 days). It is inferred from the results that Bacillus cereus to be more effective in reducing pH, BOD, and COD than the bacterium, Pseudomonas aeruginosa in the untreated tannery effluents.

Abstract Reactive dyes are essential materials for the modern lifestyle due to rapid industrialization and urbanization, but they cause adverse effects on the environment. This research work aimed to decolourize the synthetic aqueous solution containing Reactive Black B (RBB) dye using electrocoagulation (EC) process with iron electrodes in batch reactor. The effect of operational parameters such as initial pH (3–9), the distance between electrodes (0.5–2 cm), current density (1.1–8.4 mA/cm2) and initial dye concentration (100–400 mg/L), was investigated in the presence of sodium chloride to maintain the conductivity of electrolytes. Under optimal value of process parameters, high decolourization (99.6%) was obtained at 25 min. The experimental data showed that pseudo-second order kinetics with a correlation coefficient (R2 = 0.97) and Sips isotherm with a correlation coefficient (R2 = 0.98) were found to be well fitted for kinetic and adsorption equilibrium models, respectively. The economic efficiency was also calculated on the basis of electrical energy consumption (EEC), specific electrical energy consumption (SEEC), and current efficiency, respectively. Moreover, characterization of EC generated sludge was also carried out by proximate analysis, IR spectra and XRD analysis. The results revealed that EC process using Fe electrode is quite efficient and clean process for decolourization of reactive dye from aqueous solution.

Biodegradation using sequencing batch reactor is one of the best method of treating the wastewater from the diary industries. Milk and milk based products has become most essential and important role in day-to-day life of human. The raw milk undergoes various processing in dairy industries to produce other milk based products. The large quantities of water and other chemicals are required in a diary plant. The volume of water used in a diary industry varies with respect to the availability of water, processing method and type of flow. The waste water after every step of processing is discharged into either the natural water bodies or to the environment which alters the ecological balance. This research work on the laboratory scale model is used for the analysis and treatment of dairy industry wastewater. The parameters studied are the biological oxygen demand, chemical oxygen demand, dissolved oxygen, total dissolved solids, suspended solids, pH and other substances present in the diary waste water. In this study, biodegradation of dairy wastewater was investigated under a sequencing batch reactor under aerobic conditions. It is performed on three different phases with variable reaction time to study the reductions in BOD, COD and other parameters respectively.
