The influence of the addition poultry manure on thermophilic acid co-fermentation sewage sludge and wine vinasse was studied. For this, discontinuous tests were carried out to determine potential for hydrogen production (BHP tests) 50:50 mixtures with different amounts (10 g/L, 20 g/L 30 g/L). performance determined under tested conditions. experimental results revealed values TCOD SCOD, TS VS, similar in all tests, removal efficiencies lower than 25%. Likewise, an increase volatile fatty...
This study responds to the need optimise anaerobic digestion achieve integral valorisation of waste in a sustainable way, obtaining maximum yields production biofuels and biofertilisers. To benefits this technology, co-digestion with phase separation by temperature microorganisms (TPAD) sewage sludge from agri-food sector (poultry manure vinasse) was tested. end, each optimised separately applying different hydraulic retention times (HRT) first thermophilic acidogenic then mesophilic...
Ethanol production implies in by-products generation, mainly vinasse and stillage, respectively generated from sugarcane corn ethanol flex plants. Both require efficient treatment routes to avoid environmental side-effects support energy recovery. Accordingly, the aim of this study was evaluate techno-economic potential bioenergy (electric thermal energy) anaerobic digestion (AD) stillage. Three scenarios were defined: (a) Scenario 1, AD vinasse; (b) 2, stillage; (c) 3, stillage an...
This study arose in response to the management of different organic wastes generated locally, which cause environmental damage. These could be used obtain biogas and class A biosolids through anaerobic digestion. For this purpose, mesophilic tri-digestion sewage sludge (S), wine vinasse (V) poultry manure (PM) (49.5:49.5:1) was studied an improved way compared bi-digestion SV (50:50) mono-digestion S. Tests were carried out digesters, at laboratory scale, compare benefits hydraulic retention...
The present study investigated the influence of hydraulic retention time (HRT) in temperature-phase anaerobic co-digestion (TPAcD) for methane production. reactors were started-up with a mixing ratio 49.5:49.5:1 sewage sludge, wine vinasse and poultry manure. TPAcD was operated at thermophilic temperatures first stage mesophilic second stage. constant HRT 5 days, while methanogenic optimized under 15, 12, 10, 8, 5, 4, 3 days. best results obtained an 12 days stage, 56.35 % volatile solids...
A two-stage anaerobic co-digestion system has been proposed, comprising a first acidogenic stage at different temperatures, where biohydrogen is obtained; and second mesophilic methanogenic biomethane obtained. The objective of this research was to evaluate the biochemical hydrogen potentials (BHP) temperature ranges, their effect on methane subsequently carried out with effluents from BHP, in batch trials. Also, adding third co-substrate (poultry manure) mixture sewage sludge wine vinasse....
The present work consisted of the energetic valorization sludge from wastewater treatment plants and discharges wine sector by means anaerobic co-digestion. was approached through application two different processes: a) single-stage mesophilic digestion process (35 °C) and, b) Temperature - Phased Anaerobic Digestion (TPAD) with separation microorganisms: thermophilic acidogenic (55 methanogenic phases. Mesophilic biodegradability tests (BMP) were developed to determine biogas (methane)...
ABSTRACT Autotrophic ammonia-oxidizing bacteria (AOB) are of vital importance to wastewater treatment plants (WWTP), as well being an intriguing group microorganisms in their own right. To date, corroboration quantitative measurements AOB by fluorescence situ hybridization (FISH) has relied on assessment the ammonia oxidation rate per cell, relative published values for cultured AOB. Validation cell counts basis substrate transformation rates is problematic, however, because cell-specific...
