Biogas Production from Sago (Tapioca) Wastewater Using Anaerobic Batch Reactor

Abstract

In the present study, we have developed a batch reactor setup to monitor the formation of biogas using sago (cassava) wastewater for the first time. The experimental parameters like pH, COD, BOD, volatile solids, have been tested to optimize the production of biogas. The liberated biogas was analyzed and found that, about 65 – 70 % of methane and remaining 20–25 % of CO2. Sago effluent contains large amount of organic material which has a potential to cause water pollution. In order to reduce this problem, an experiment was conducted to remove organic material and biogas recovery from sago effluent using lab scale batch reactor. The biogas produced in the first reactor of 750 ml feed was 3393 ml per liter of liquid waste and similarly the biogas produced in the second reactor of 1250 ml feed was 3068 ml per liter of liquid waste.

Lovastatin production by an oleaginous fungus, Aspergillus terreus KPR12 using sago processing wastewater (SWW)

“…Applications of SWW include biogas [ 22 , 23 ], hydrogen [ 24 , 25 ], microbial lipid and biodiesel production using oleaginous yeast and fungi [ 21 , 26 – 29 ]. Several oleaginous fungi and yeasts were isolated previously from this wastewater for biodiesel production with simultaneous removal of pollutants [ 27 – 31 ].…”

Synthesis of A Sustainable Sago-Based Value Chain via Fuzzy Optimisation Approach

“…Different plantation g produces palms with different starch content due to different soil conditions, which can also be found in [8]. To determine the economic and environmental performance of the value chain proposed in this study, unit costs and CFP emission of producing intermediate d and end product z via technology 1 c and technology 2 e are estimated from literature and summarized in Table 1 [12]- [18].…”

Application of Response Surface Methodology for Sago Wastewater Treatment by Ozonation

“…According to literature various technologies have been implied to treat sago wastewater. Some widely used methods are high-rate anaerobic treatment such as Microbes [4]; anaerobic reactors [5][6][7][8], Three phase fluidized bed bioreactor [9]; activated sludge and cow dung slurry [10], sago-sludge treatment using earthworm [11] and utilizin g sago waste as an adsorbent for removing Cu ions [12].…”
