  • Anaerobic treatment of crude glycerol from biodiesel production

    In this study, we evaluated the use of an up-flow anaerobic sludge blanket (UASB) reactor to treat crude glycerol obtained from cottonseed biodiesel production. The laboratory-scale UASB reactor (7.0 L) was operated at ambient temperature of 26.5°C with chemical oxygen demand (COD) concentrations between 0.5 and 8.0 g/L. The volatile fatty acid contents, pH, inorganic salt contents and biogas ...

  • Beating treatment to enhance digestibility of fresh grass

    Anaerobic digestion (AD) is one of the most popular biomass conversion technologies. AD can be further divided into four stages: pre–treatment, digestion, gas upgrading and digestate. The main goal of pre–treatment is to improve degradability of the material in order to enhance gas production and anaerobic digester performance. Beating treatment as a new mechanical treatment technique has been ...

  • Biohydrogen production from tequila vinasses using a fixed bed reactor

    In Mexico, the industrial production of tequila leads to the discharge of more than 31.2 million of m3 of vinasse, which causes serious environmental issues because of its acidity, high organic load and the presence of recalcitrant compounds. The aim of this research was to study the feasibility of a fixed bed reactor for the production of biohydrogen by using tequila vinasse as substrate. The ...

  • Towards a sustainable use of food waste: influence of urea on biogas production potentials of selected fruit wastes in Addis Ababa, Ethiopia

    This study evaluates the influence of adding urea on biogas (methane) production potentials of selected fruit wastes. Using standard methodology, the finding revealed that all the fruit wastes are ideal substrates for biogas production. The ultimate biogas yield on anaerobic digestion of fruit waste feeds, avocado, banana, and mango, are 0.48, 0.57, 0.53 l/g VS without urea supplement and 0.76, ...

  • Allweiler Peristaltic Pumps: an ingenious solution for biogas plants

    Installations and plants used to process biomass for the production of biofuels must be capable of handling difficult conditions. For example, intermediate products in the production of biodiesel exhibit a high level of chemical aggressiveness. Accordingly, pumps, pipe connections, and fittings must be capable of resisting these demanding conditions. In addition, waste products usually contain a ...
