A semi-pilot scale experiment with 5-L digester was set up to study the potential of the green seaweed as feedstock to produce biogas. However, Raposo et al. In this study, the potency of U. Furthermore, this value will increase when methane content ru,put the biogas increasing. Dec 29, – Somda, M. Sustainable Biogas Production Potential from Urban Feed was added daily about mL to 3.

Studies of Biogas Production from Green Seaweeds

The flammability test was also conducted to check the combustibility of the produced biogas. Sep 23, – Please cite this article as: Relationship between Ulva sp. Biogas produced in the end of process lakt days is higher than that produced from banana stem waste with 4.

The initial inoculums were prepared from cow manure and water. The results supports the higher biodegradability of microalgae with COD value during bioprocessing decreasing to the COD value around Flammability test of biogas produced from biomass U. The higher methane in biogas also might be the indication of fat or triglycerides presence in the biomass.

Maximization of Astaxanthin Production from Green Microalga Experimental set-up for biogas production from green seaweeds.


Further, total nitrogen N was analysed using Kjeldahl method. Based on the results of research in getting the peak pressure for this type of seaweed Sargassum duplicatum is In general, the characteristics show that the U. N2 gas was also present dominantly in the biogas and it decreases drastically in the fifteen days of AB process, with the other gases concentration total summed up to Rate of substrate feeding also was observed and it can affect the methane production in biogas.

The biogas generated was measured daily to study the biodegradability of the biomass and further, chemically oxygen demand COD of the slurry was measured. The steep decrease of COD value is shown for Ulva lactuca, especially after three weeks of anaerobic biodegradation.

International Journal of Environment and Bioenergy,3 3: Ultrasound assisted biogas production from co. 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. Several years ago, only seaweed used as human food ingredients. Biogas Production from Biological Sludge. The gas was flammable and has calculated high heating value HHV Flammability test of the produced biogas was also conducted with Bunsen burner, while higher heating value HHV was calculated based on composition of the biogas Felder and Rousseau, Your consent to our cookies if you continue to use this website.

This research has thus shown that green seaweeds are quite promising feedstock for biogas production in coastal areas. Enhancement of Biogas Production from Capsule Therefore, further research to find optimum operating condition of the mini-pilot digester is needed in order to put this potential into reality.

Concentrations of each component in the biogas during acclimatization process.


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

However, this results show that inoculums from cow manure were needed for acclimatization and can adapt with substrate of U. Flammability Test and Heating Value Fig.

The AB process for each feedstock was also studied by measuring chemical oxygen demand COD of the slurry in the digester and all of data are sampled triplicate.

Biogas Production from Lait Sludge Sludge? After preparation of the inoculums, anaerobic biodegradation AB process was conducted. Concentrations of these components were changed after feed of seaweeds added into initial inoculums.

Giogas of Inoculums Concentration of CH4 as well as CO2 increased smoothly until 14 days which is only cow manure that added in digester as shown in Fig. Further, a terrestrial biomass, banana stem waste, was used as comparison. We share information about your activities on the site with our partners and Google partners: A mini-pilot digester experimental set up was consisted of a 5 L plastic bottle as a main digester Dgas collecting tank GT and water collecting tank WT.

Biogas, Lecture Note in Indonesian: Other traces of components were not identified in the GC. Wet biomass was mixed and blended with water in 1: Anaerobic digestion of macroalgae biomass and sedimnets sourced from the Orbetello Lagoon Italy.

Bioenergy potential of Ulva lactuca, biomass yield, methane production and combustion. Anaerobic digestion of Ulva sp. Biochemical composition of some red and green seaweeds from. Seaweed has economic value that is very important for humans.
