“…Terdapat tiga faktor yang mempengaruhi kinerja dari reaktor yaitu beban influen, perubahan konsentrasi influen dan HRT. Peningkatan beban influen beresiko terganggunya proses di dalam reaktor akibat terjadinya akumulasi konsentrasi asam volatil (Kerroum, 2012) yang berpengaruh pada menurunnya efisiensi penyisihan COD.

AbstrakDalam penelitian ini, biowaste yang digunakan adalah sampah pasar. Sampah pasar menyumbang sekitar 12% dari berat total sampah kota. Upflow Anaerobic Fixed Bed Reactor (UAFB-R) yang digunakan dalam penelitian ini memakai media penunjang batu apung dengan resirkulasi efluen dan tanpa pengatur pH. Penelitian ini bertujuan untuk melihat kinerja UAFB-R dengan media penunjang batu apung dalam penyisihan organik dan pembentukan biogas terutama gas metan biowaste fasa cair. Hydraulic Retention Time UAFB-R ditentukan sebesar 6 hari dengan volume operasi sebesar 9 liter. Variasi beban organik influen dalam penelitian adalah ± 0,32 kg COD/m hari di kondisi tunak, semakin besar beban organik influen maka efisiensi penyisihan COD semakin kecil dan rasio TAV/Alkalinitas semakin besar. Namun, semakin kecil beban organik influen maka komposisi dan volume gas metan serta methane yield cenderung semakin besar. Saat variasi beban influen ± 0,96 kg COD/m 3.hari dihasilkan volume gas metan terbesar sebanyak 1,77 liter, sedangkan saat variasi beban organik influen ± 0,64 kg COD/m 3.hari dicapai komposisi gas metan dan methane yield terbesar sebesar 77,4% dan 0,249. Selain itu, semakin tinggi konsentrasi sulfat maka maka volume biogas yang terbentuk menjadi lebih kecil.Kata kunci: batu apung, biogas, biowaste, UAFB-R AbstractThe biowaste utilized in this study was market waste. Market waste accounts for approximately 12% of the total weight of municipal solid waste. Upflow Anaerobic Fixed Bed Reactor (UAFB-R) used in this research was equipped by pumice stone as supporting media, effluent recirculation, and sans pH regulator. The aim of this study was to investigate the performance of UAFB-R supported by pumice stone in organics removal and biogas formation, mainly methane, from liquid phase biowaste. The determined Hydraulic Retention Time of UAFB-R was 6 days with operation volume of 9 liter. Influents of organic load were varied to ± 0.32 kg COD/m day in steady state condition, the greater the organic load of influent, the smaller the COD removal efficiency and the bigger the TAV/Alcalinity ratio. However, the smaller the organic load of the influent, the composition, volume and yield of methane tend to be greater. 1.77 Liter of methane was obtained from ± 0.96 kg COD/m 3. day influent, meanwhile the highest amount of methane composition and yield was achieved from influent with organic load of ± 0.64 kg COD/m 3. day, which was 77.4% and 0.249 respectively. In addition, the volume of biogas formed dropped smaller with the increase of concentration of sulfate.

“…First, the complex polymers are hydrolyzed into water-soluble monomers and oligomers by the hydrolytic and fermentative bacteria. Then, the acidogenesis consists in the transformation of the soluble organic molecules into volatile fatty acids, organic acids, hydrogen, carbon dioxide, alcohols and acetate by acidogenic bacteria [1,2]. This reaction is followed by the acetogenesis, during which the products of hydrolysis and acidogenesis are converted into acetate and carbon dioxide by the action of acetogenic bacteria [1,2].…”

Acetotrophic methanogens transform acetate into methane and carbon dioxide, while hydrogen methanogens combine hydrogen and carbon dioxide to form methane and water [1,2].

Anaerobic digestion is a widely used process for waste treatment and energy production. This natural process takes place in a controlled environment, anaerobic digesters. Mixing is one of the main operating parameters. The understanding of the flows during the agitation of the medium is crucial for the optimization of the process yield. In fact, the mass and heat transfers are enhanced by the agitation. However, the complex biochemical reactions can be inhibited with overly vigorous agitation. A detailed and in-depth understanding of the phenomena occurring during agitation requires modeling studies. In this chapter, we propose a general approach, based on computational fluid mechanics (CFD), to analyze the mechanical mixing of an anaerobic reactor. We apply this work to the anaerobic digestion of the sugarcane vinasse, which is a liquid waste generated during the production of alcohol. The single-phase Reynolds-averaged Navier-Stokes (RANS) simulations of mechanical agitation of Newtonian fluids for different rotational speeds are presented. The equations system is closed with the standard k-epsilon turbulence model. The flow field is analyzed with the velocity profiles, the Q and Lambda2 fields, the pressure and the vorticity.

“…Biogas can be used as a fuel in other country for the purpose of heating, cooking and a lot more, biogas can be more compressed like a natural gas and can also be used to power motor vehicle tyre tube. Biogas can be derived from the following such as agriculture waste, animal manure, sewage, green waste, poultry, cow dung, human excrement, expired food and in addition to factory organic liquid [4]. The process of biogas formation is divided into four stages which are hydrolysis, acidification, methanogenesis and acetogenesis.…”

Biogas production from cow dung for powering a tyre tube was investigated, using a 20litre capacity prototype biogas digester, fabricated in the Lagos state university (LASU) research laboratory. The experiment was batch operated and daily gas yield from the digester was monitored for 21 days. The ambient and slurry temperatures, PH were also monitored. Two important aspects of the biogas itself is digester and starter. This Research aim to fabricate a digester that can be used to convert a cow dung into methane for powering a tyre tube and the objective to determine whether cow dung from ranch can produce methane. In this study a mini biogas digester fabricated and tested for organic waste, thirty-five (35) kg of the cow dung, water and starter was used. (The starter that used in this study is silica gel). The cow dung inserted into the digester through the inlet pipe, and kept for three weeks. The ratio of cow dung water is 1:2. The result obtained from the biogas production showed that methane has 67.9%. This result show that these waste could be a source of a renewable gas if managed properly since the waste sluggishly continued gas production after 21 days retention time.
