The search for alternative fuel sources to replace non-renewable energy is a highly relevant topic in current research studies. Both biomethane and biohydrogen can be obtained from several anaerobic biological processes, which have some advantages over traditional supply chains, especially due the ability use various wastes and/or wastewaters as feedstock biogas production, considered renewable fuel. These features combined with low inputs support potential of these processes play key role...
Hydrogen production from hydrothermally pretreated (200 °C for 10 min at 16 bar) sugarcane bagasse was analyzed using response surface methodology. The yeast extract concentration and the temperature had a significant influence hydrogen (p-value 0.027 0.009, respectively). Maximum (17.7 mmol/L) observed with 3 g/L 60 (C10). In this conditions were produced acetic acid (50.44 mg/L), butyric (209.71 ethanol (38.4 methane (6.27 mmol/L). Lower productions (3.5 mmol/L 3.9 under C7 (2 of extract,...
The Barapullah drain crosses through New Delhi, India, and transports millions of cubic meters stormwater, municipal sewage industrial to the Yamuna River. Seasonal variations ambiguous annual discharges cause 20-fold fluctuations in hydraulic flows, pollutants type concentration. Furthermore, Delhi is among most densely populated areas on planet, with limited surface area high water stress. Dissolved Air Flotation (DAF) units are known be highly compact, robust, an efficient suspended...
This study evaluated the potential of a microbial consortium collected from pulp and paper mill wastewater treatment plant (WWTP) for converting cellulose to hydrogen, biogas organic acids.Fermentation tests were conducted in batch reactors fed with different concentrations as substrate: (C1) 2.0 g L -1 ; (C2) 5.0 (C3) 10.0 .The parameters investigated biogas, acids, carbohydrates pH.The maximum hydrogen production was 14.77, 39.25 22.53 mmol , methane 4.40, 3.72 9.56 C1, C2 C3,...
Oil palm empty fruit bunch (OPEFB) is an abundant waste that commonly incinerated, causing environmental pollution. In this study, alternative management approach was investigated to produce value-added syngas from OPEFB using solar steam gasification. The three operating variables were temperature (1100–1300 °C), H2O/OPEFB molar ratio (1.7–2.9), and flowrate (0.8–1.8 g/min). Central composite design (CCD) conducted investigate optimise the effects of these on H2/CO fuel energy conversion...
Abstract Aim: Microbial communities play a central role in environmental process such as organic matter mineralization and the nutrient cycling aquatic ecosystems. Despite their ecological importance, variability of structure archaeal bacterial freshwater remains understudied. Methods In present study we investigated richness density archaea bacteria water column sediments Itupararanga Reservoir. We also evaluated relationship between biotic abiotic characteristics. Samples were taken at...
