چکیده
This research aimed to evaluate the effectiveness of various diffusers in a bioreactor for producing liquid organic fertilizer (LOF) using cow urine and slurry waste as materials. LOF was produced by treating with Urine-Single Orifice Diffuser (USOD), Urine-Coarse Bubble (UCBD), Urine-Fine (UFBD), Slurry-Single (SSOD), Slurry-Coarse (SCBD), Slurry-Fine (SFBD) equipped water pump an external aerator unit. The circulated agitated biomass at discharge 10 L/min. Meanwhile, unit pumped air into bioreactor, which absorbed 45 also caused agitation fermented biomass. Several variables were observed during fermentation process, including temperature, acidity (pH), total dissolved solids (TDS), C/N ratio, electrical conductivity (EC), biological oxygen demand (BOD), microbial population, cation exchange capacity (CEC), other chemical properties. had pH, matter content, EC, TDS, BOD, CEC values 6.3–6.8, 28.0–37.0°C, 20.77–22.46%, 54630–62369.24 µmS, 7543–11700 ppm, 1.2–2.6 mg/L, 3.2–7.5 log CFU, 12.3–14.1, 29.98 me/100 g, respectively. macro micro nutrient contents bio-urine 12.72–12.96%, 3.09–3.25%. those bio-slurry 12.35–12.99% 2.39–2.72%. These characteristics accordance Indonesian National Standard (SNI).

In this paper, a CFD model of syngas flow in slurry bubble column was developed. The model is based on an Eulerian-Eulerian approach and includes three phases: slurry of solid particles suspended in paraffin oil and syngas bubbles. Numerical calculations carried out for catalyst particles, bubble coalescence and breakup included bubble-fluid drag force and interfacial area effects. Also, the ef...

The performance of a hybrid bubble column/biofilter (HBCB) bioreactor for the removal of dichloromethane (DCM) from waste gas streams was studied in continuous mode for several months. The HBCB bioreactor consisted of two compartments: bubble column bioreactor removing DCM from liquid phase and biofilter removing DCM from gas phase. Effect of inlet DCM concentration on the elimination capacity ...
متن کاملCommercial scale slurry bubble column reactor optimization
An in-depth numerical study has been carried out to investigate a high-pressure commercial scale (2–8 meter diameter) slurry bubble column reactor (SBCR). Typical superficial gas velocities are in the range of 0.5–3 m/s, and overall vapor hold-ups are in the range of 0.45–0.85. The study revealed that steady compartmental reaction models do not match plant data when reaction time constants are ...

A biotechnology for aerobic conversion of food waste into organic fertilizer under controlled aeration, stirring, pH and temperature at 55-65 degrees C, is proposed. To maintain neutral pH at the beginning of the bioconversion 5% CaCO3 was added to the total solids of the food waste. The addition of 20% horticultural waste compost as a bulking agent to the food wastes (w.w./w.w.), improved the ...
