enzymatic extract preparation from pseudomonas aeruginosa km110 under accession no. hq730879 with lipase activity (0.3 u/ml), was used to perform enzymatic hydrolysis pretreatment of a synthetic dairy wastewater with 1000 mg/l total fat content. the pretreatment was optimized for 48 h hydrolysis time, at 45æ% c with 10% v/v enzymatic extract. the biological treatment of synthetic dairy wastewat...
Anaerobic oxidation of methane (AOM) in marine sediments is an important global methane sink, but the physiological characteristics of AOM-associated microorganisms remain poorly understood. Here we report the cultivation of an AOM microbial community from deep-sea methane-seep sediment using a continuous-flow bioreactor with polyurethane sponges, called the down-flow hanging sponge (DHS) biore...
Abstract The laundry business sector is expanding quickly nowadays. However, the industry still dealing with issue of processing detergent wastewater. Anaerobic and aerobic bioreactors may efficiently solve this problem. This narrative review aims to assess feasibility using anaerobic for wastewater treatment. Its advantages disadvantages idea combining multi-media filtration UV light in treatm...
Membrane bioreactor (MBR) is an efficient wastewater treatment technology, which produced by combining membrane technology and biological has the characteristics of stable water quality shock load resistance, been widely used in domestic treatment. Anaerobic ammonia oxidation (ANAMMOX) a new type denitrification with advantages low energy consumption, oxygen demand, carbon source saving good ec...
This paper focuses on the recent research in the development of anaerobic membrane bioreactors in wastewater treatment. Anaerobic wastewater treatment technology is gaining increasing attention due to its capacity to convert wastewater BODs to usable biogas with relatively low energy consumption. The anaerobic membrane bioreactor (AnMBR), which is a combination of the anaerobic biological waste...
The selection of optimum high strength wastewater treatment process is complicated. Be familiar with wastewater treatment methods is not enough to design a plant. In this research, five alternative wastewater treatment methods (upflow anaerobic sludge blanket (UASB) + membrane bioreactor (MBR), UASB + Extended aeration (EA), Anaerobic baffled reactor (ABR), anaerobic lagoon (ANL) + aerated lago...
Although bioreactor landfills have many advantages associated with them, challenges remain, including the persistence of ammonia-nitrogen in the leachate. It has been suggested that ammonia-nitrogen is one of the most significant long-term pollution problem in landfills and is likely a parameter that will determine when landfill postclosure monitoring may end. The fate of nitrogen in bioreactor...
Biological hydrogen production by anaerobic bacterium, Rhodospirillum rubrum was studied in batch and continuous bioreactors using synthesis gas (CO) as substrate. The systems were operated at ambient temperature and pressure. Correlations available in the literature were used to estimate the gas-liquid mass transfer coefficients (KLa) in batch reactor. Based on experimental results for the con...
Biogas is a flammable gas mixture that can be produced by anaerobic digestion of organic wastes. It contains 50-65% methane gas, 35-50% carbon dioxide (CO2) and 100-1000 ppm hydrogen sulfide (H2S) in biogas. One the biggest disadvantages biogas production technologies cost purification convert to biomethane. In this study, portable, intermittent bioreactor 20 liter gasometer were designed. The ...
