Enhancement of Biogas Production from Macroalgae Ulva latuca via Ozonation Pretreatment
نویسندگان
چکیده
One of the dominant species green algae growing along Mediterranean coast Egypt is Ulva lactuca. Pretreatment can have a major effect on biogas production because hydrolysis cell wall structure rate-limiting stage in anaerobic digestion (AD) process. The use ozone, new pretreatment, to boost from lactuca was investigated this study. Ozonation at various dosages used contrast untreated biomass, and performance subsequent mesophilic AD using two separate inoculums (cow manure activated sludge) examined. findings indicated that, different studies, ozonation pretreatment showed substantial increase yield relative algae. With an ozone dose 249 mg O3 g–1 VS algal for lactuca, highest output (498.75 mL/g VS) achieved cow inoculum. evaluation FTIR, TGA, SEM, XRD revealed impact integrity breakage, which thus established as main contributor improving production.

Effects of organic loading rate on biogas production from macroalgae: Performance and microbial community structure.
Macroalgae biomass has been considered as a promising feedstock for biogas production. In order to improve the efficiency of anaerobic digestion (AD) of macroalgae, semi-continuous fermentation was conducted to examine the effects of organic loading rate (OLR) on biogas production from Macrocystis pyrifer. Results showed that, under OLRs of 1.37, 2.74, 4.12 and 6.85kgVSsubstrate/(m3·d), the ave...
متن کاملPretreatment of Straw Fraction of Manure for Improved Biogas Production
Pretreatment of straw separated from cattle and horse manure using Nmethylmorpholine oxide (NMMO) was investigated. The pretreatment conditions were for 5 h and 15 h at 120 °C, and the effects were evaluated by batch digestion assays. Untreated cattle and horse manure, both mixed with straw, resulted in 0.250 and 0.279 Nm CH4/kgVS (volatile solids), respectively. Pretreatment with NMMO improved...
متن کاملPretreatment Methods of Organic Wastes for Biogas Production
During biogas production, the rate-determining step for the conversion of complex organic matter is the hydrolysis. Different pretreatment methods aid in facilitating the anaerobic digestion by increasing the rate of organic matter hydrolysis. This in effect results in enhanced production of biogas and aids in waste stabilization as well as disposal. This review gives an overview of the methods...
متن کاملPretreatment of Cottage Cheese to Enhance Biogas Production
This study evaluated the possibility of pretreating selected solid fraction of an anaerobic digester treating food waste to lower the hydraulic retention time and increase the methane production. The study investigated the effect of different pretreatments (thermal, chemical, thermochemical and enzymatic) for enhanced methane production from cottage cheese. The most effective pretreatments were...
