Modelling the Biogas Production Kinetics of Anionic Surfactants Exposed Anaerobic Fermentation Process Using Sigmoidal Growth Functions

Abstract The selected techniques were reviewed and their technological aspects were characterized in the context of multi-phase flow for biogas production. The conditions of anaerobic fermentation for pig slurry in a mono-substrate reactor with skeleton bed were analysed. The required technical and technological criteria for producing raw biogas were indicated. Design and construction of the mono-substrate model, biogas flow reactor, developed for cooperation with livestock buildings of various sizes and power from 2.5 kW to 40 kW. The installation has the form of a sealed fermentation tank filled with a skeletal deposit constituting a peculiar spatial system with regular shapes and a rough surface. Incorporating a plant in such a production cycle that enables the entire slurry stream to be directed from the cowshed or pig house underrun channels to the reactor operating in the flow mode, where anaerobic digestion will take place, allows to obtain a biogas. The paper presents preliminary results of experimental investigations in the field of hydrodynamic substrate mixing system for biogas flow assessment by the adhesive bed in the context of biogas production. The aim of the study was to assessment and shows the influence of the Reynolds number on the biogas resistance factor for the fermentation process in mono-substrate reactor with adhesive deposit. The measurement results indicate a clear effect of the Reynolds number in relation to the descending flow resistance coefficient for the adhesive bed.

Biogas is one of energy that can be produced by anaerobic fermentation of the organic compounds. The objective of this study was to determine the effectiveness of the utilization of waste of media mushroom growth (baglog) with sawdust as raw material for biogas with cow dung activators. The study was conducted through anaerobic fermentation of the samples containing waste baglog (sample 1) and sawdust (sample 2), with the addition of cow manure activator to each sample. Both of these samples do anaerobic fermentation for 32 days, then measuring the volume of biogas every 4 days for 32 days. Methane content in samples 1 and 2 measured by using gas chromatography. To see the effect of the addition of activators cow dung biogas volume measurement was carried out with cow dung without addition baglog waste and sawdust. The process of degradation baglog and sawdust with an activator of cow dung could be observed in some of the parameters through total solids (TS), total volatile solids (TVS), volatile fatty acids (VFA), the degree of acidity (pH), and C/N ratio. The results showed that effectiveness of sample 1 resulted in the everage of total volume biogas 28% higher than sample 2. The content of methane in sample 1 and sampel 2 was 54% %, and 0.21% respectively. The fermentation process biogas production in this experiment was carried out at pH 7, with a value of TS, TVS and VFA showed a decrease trend after the fermentation process, C/N ratiowas lower than the baglog waste sawdust until day 32 retention time.

POME or palm oil mill effluent is currently still a waste problem that has not been utilized optimally. POME waste has the potential for renewable energy in the form of biogas, but some research results have shown that production is not optimal, so the addition of cow dung needs to be done to increase biogas production because methanogen bacteria found in cow dung help to maximize the anaerobic fermentation process and methane production. This research was conducted to determine the potential for biogas production from a mixture of POME and cow dung for 25 days by conducting a study of the biogas production process. The results of this study indicate that the biogas pressure increases with the addition of the loading rate, which is 101.102 N/m2/day to 101.107 N/m2/day with a daily biogas production of 0, 24247 liters/day with a total accumulation of biogas production for 25 days of 6.1 liters.

The aim of the work is to determine and analyse concentrations of individual biogas components according to the used raw materials based on plant biomass. The measurement is focused on biogas production depending on input raw materials like maize silage, grass haylage and rye grain. The total amount of plant biomass entering the fermenter during the measurement varies at around 40% w/w, the rest is liquid beef manure. The measured values are statistically evaluated and optimised for the subsequent effective operation of the biogas plant. A biogas plant operating on the principle of wet anaerobic fermentation process is used for the measurement. The biogas production takes place during the wet fermentation process in the mesophile operation at an average temperature of 40°C. The technology of the biogas plant is based on the principle of using two fermenters. It follows from the measured results that maize silage with liquid beef manure in the ratio of 40:60 can produce biogas with a high content of methane; this performance is not stable. At this concentration of input raw material, the formation of undesirable high concentrations of hydrogen sulphide occurs as well. It is shown from the results that the process of biogas production is stabilised by the addition of other components of plant biomass like grass haylage and rye grain and a limitation of the formation of hydrogen sulphide occurs. It follows from the results that the maize silage should form about 80% w/w from the total amount of the plant biomass used.

Biogas is one of the energy sources originating from livestock waste, besides being environmentally friendly (renewable energy), it can also be used for sustainable energy. Biogas is a mixture of gases resulting from an anaerobic fermentation process from livestock manure (cow). The purpose of this study was to determine the effect of adding various urea concentrations and heating in deep biogas production. This study applied a completely randomized design (RAL) with two treatment factors: heating (heating and without heating) and urea concentration (2%, 4%, 6%, 8%). Observations carried out in the form of measuring the temperature of biogas media, gas volume, CO2, the volume of methane gas, and the time of biogas formation. Variant analysis showed that the heating interaction and urea concentration showed a significant effect (P <0.05) on the measurement of biogas media temperature, gas volume, CO2, methane volume, and biogas formation time. The results showed that the combination of heating treatment with 8% urea concentration was the best treatment in producing biogas with the characteristics of gas volume of 16.67 ml, CO2 content of 0.08%, methane volume of 15.49 ml, with the time of biogas formation which is on the day 10.

Production Stage

This paper performs a batch experiment for pre-acidification treatment and methane production from chicken manure by the two-stage anaerobic fermentation process. Results shows that the acetate was the main component in volatile fatty acids produced at the end of pre-acidification stage, accounting for 68% of the total amount. The daily biogas production experienced three peak period in methane production stage, and the methane content reached 60% in the second period and then slowly reduced to 44.5% in the third period. The cumulative methane production was fitted by modified Gompertz equation, and the kinetic parameters of the methane production potential, the maximum methane production rate and lag phase time were 345.2 ml, 0.948 ml/h and 343.5 h, respectively. The methane yield of 183 ml-CH4/g-VSremoved during the methane production stage and VS removal efficiency of 52.7% for the whole fermentation process were achieved.
