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.

Tannery Waste Water

Tannery in Bangladesh seems a source of pollution load and waste water to all because there are 270 registered tanneries where approximately 220 MT raw hides and skins are taking for the production of leather in Bangladesh. The leather industry has crossed the record $1-billion mark in exports in 2013-2014. According to the Department of Environment, the tanneries discharge 22,000 cubic meters of untreated liquid toxic waste daily. These pollution load and waste water should need treatment to make environmentally sustainable and living. From this point of view, we worked on tannery waste water processing. The paper highlights the initiation of Algal treatment with chemical coagulation process aided by natural coagulant for waste water processing in Bangladesh. The methodology of this process starts with mixing of waste water from different section of beam house operations at a definite ratio. The mixer takes nearly six hours to settle down. After sedimentation, the turbidity decreases at a reasonable amount i.e. 1428 NTU whereas before sedimentation it was 9050 NTU (2100P Turbid Meter of HACH). Later the supernatant was collected for algal treatment. After algal treatment the turbidity reduced to 530 NTU from 1428 NTU and the DO level increased up to 4.48 mg/L at 33.6 °C (HQ 40d of HACH) where DO level was 0.24 mg/L at 33.6°C in raw mixer. In addition, the amount of alum as chemical coagulant was reduced in tannery waste water treatment by using indigenous snail shell powder as coagulant aid in conjunction with alum. In case of untreated sample after sedimentation required alum dozing was 6 mL/ 40 mL sample. After algal treatment, required alum dozing reduced to 4 mL/ 40 mL sample. By adding 3 mL/ 40mL liquid natural coagulant as coagulant aid, alum dozing was further minimized to 1 mL/ 40mL sample. The odour was more tolerable than raw mixer after algal treatment but after adding alum aided by natural coagulant, the odour was more acceptable than before. The diversified technique can hopefully reduce a reliable chemical cost in treatment process, considerable amount of pollution load and increase DO level and thus make effluent environment friendly to discharge. Finally, the DO level increases up to 6.56 mg/L at 33.7 0C and turbidity reduces to 183 NTU, pH reduces to 7.6, odour turns to be tolerable limit.
