Biogas Production from Biological Sludge Sludge? Ulva lactuca is one of green seaweeds found in many coastal areas of Indonesia.

University of Lampung | LPPM-UNILA Institutional Repository (LPPM-UNILA-IR)

Sep 23, – Please cite this article as: The objective of this research is to investigate the potential of green seaweed Ulva lactuca from Indonesia as a feedstock for biogas production. The higher methane in biogas also might be the indication of fat or triglycerides presence in the biomass.

Sustainable Energy Ireland Report. An overview relating to methane yields and experimental procedures. N ratio of biomass were around The biogas generated was measured daily to study the biodegradability of the biomass and further, oaut oxygen demand COD of the slurry was measured.

Kelly and Dworjanyn noted that inoculums which were not acclimating can be direct use for substrate of marine seaweeds but the AB process performs rumpjt process.

Effect of ISR towards productivity of methane acarbon dioxide b and hydrogen c in biogas from U. Hence, most of current research with regard to energy has been focusing in finding invention of new energy and renewable energy as well as efficient utilization of energy in many processes Sitompul et al. With the promising results, further research and development works, especially to find optimum operating condition of the mini-pilot digester is needed.


The influence of the process parameters will be determined by analyzing substrate, percolate, fermentation residue and biogas during the dry Marine biomasses such as green seaweeds are reported to contain far less lignin than terrestrial biomass and thus conceptually making them good feedstock for biogas production.

Furthermore, yield of hydrogen seems not influenced by the ISR. Taken from the website, www. Biomass conversion to energy is a very crucial step for producing renewable energy from biomass. Effect of ISR toward cumulative volume of biogas.

International Journal of Environment and Bioenergy,3 3: This procedure was conducted until 30 days and the volume of biogas as well as composition of biogas was measured daily. Furthermore, total N that resulted was low 1.

Studies of Biogas Production from Green Seaweeds

The juice was then mixed with inoculums prepared from earlier processes and 3. This research has thus shown that green seaweeds are quite promising feedstock for biogas production in coastal areas.

Conclusions Green seaweeds, especially U. In general, the above results of biogas production from semi-pilot scale digester show that green seaweeds U. Sustainable Biogas Production Potential from Urban Furthermore, this value will increase when methane content in the biogas increasing.

Making biogas process bioyas conducted at the Laboratory of Marine Science. The high sulfur can affect activity of methanogenic bacteria since it can also be activated by sulfuric reducing bacteria SRB as reported by Migliore et al.

The sampling of the biogas was taken by a syringe through a sampling port before GT. Rate of substrate feeding also was observed and it can affect the methane production in biogas. The higher ISR will increase the yields of methane in biogas while carbon dioxide gas dqri.

Biochemical composition of some red and green seaweeds from. Furthermore, mL feed was added every 3 days and slurry also was removed at the same time. Furthermore, the world energy demand has increased significantly during the rumpkt millennium and sari predicted to be quadrillion BTU in from quadrillion in World Energy Buogas, Process Parameter in anaerobic biodegradation process of U.


The HHV is still lower compared with that of biogas from cow manure and that of other solid fuels but that of U. The purpose of this study was to determine the potential of seaweed species Sargassum duplicatum and Caulerpa racemosa for the manufacture of biogas as a new alternative energy sources and to know the pressure of gas contained in a lut of seaweed Sargassum duplicatum and Caulerpa racemosa as a new alternative energy sources.

The high productivity of CO2 showed that hydrolysis bacteria as well as acidogenic bacteria can fast adapt with substrate, while methanogenic bacteria still slow since the productivity dqri CH4 is low.

Volume and composition of biogas were measured daily. It has high potential growth rates than terrestrial plants McKendry,moreover high level of accessible sugars Bruton et al. In this study, the potency of U. This research was conducted in June-September N ratio ranging from Several years ago, only seaweed used as human food ingredients.

Acclimatization of inoculums is needed since it aims to adapted bacteria with feed environment. Anaerobic treatability and biogas production potential studies Biogas production from hydrothermal liquefaction Materials and Methods U.

However, this results show that inoculums from cow manure were needed for acclimatization and can adapt latu substrate of U. This result indicates that the activity of methanogenic bacteria is quite slow. N ratio in U. Ultrasound assisted biogas production from co.
