  • The use of the anaerobic baffled reactor for wastewater treatment: A review

    A review concerning the development, applicability and possible future application of the anaerobic baffled reactor for wastewater treatment is presented. The reactor design has been developed since the early 1980s and has several advantages over well established systems such as the upflow anaerobic sludge blanket and the anaerobic filter. These include: better resilience to hydraulic and organic ...

  • Treatment of distillery anaerobic effluent in a hybrid biological reactor

    The treatability of anaerobic effluent from a molasses-based distillery was studied in a shaft-type hybrid bioreactor under purely suspended growth and hybrid system containing 5 mm tyre-tube beads. The Ks, k, Y and k found as 111.29 mg/l, 0.026/h, 0.4607 and 0.0040/h respectively. The maximum COD removal was 51.7% at a loading rate of 5.250 kg d−1 m−3. The overall removal rate was 0.0431, ...

  • Effects of Macrolide Antimicrobials on the Performance of Anaerobic Treatment Systems

    An anaerobic sequencing batch reactor (ASBR) was operated to study the effects of tylosin, a macrolide antimicrobial commonly used in swine production, on treatment performance and the development of antimicrobial resistance. The addition of 1 mg/l tylosin to the reactor had no effects on the biogas production and chemical oxygen demand (COD) removal efficiency. Specific methanogenic activity ...

  • Waste treatment Wernsing Anaerobic Digestion Plant (Germany)

    Wernsing biogas plant Addrup The Wernsing biogas plant was one of the first biogas weser-ems plants to treat waste from food industry since its commission in 2001. Up to 200 tonnes of white cabbage and potatoes waste are used as main input material per day. In addition to the biogas plant, the facilities owned by the Wernsing group include a waste water treatment plant to treat the sewage ...

  • Integrated Anaerobic and Aerobic Processes for Treatment of Municipal Wastewater

    ABSTRACTIn this study, integrated anaerobic and aerobic treatment processes for municipal wastewater treatment were investigated for its feasibility to replace the existing conventional activated sludge process. Three types of anaerobic systems − anaerobic sludge blanket, anaerobic sequencing batch reactor and anaerobic filter, as the pretreatment step were studies. High solids and organics ...

  • The Effect of the Microsludgetm Treatment Process on Anaerobic Digestion Performance

    ABSTRACT Thickened waste activated sludge (TWAS) from biological treatment processes is less amenable to anaerobic digestion than primary sludge. This is due to TWAS being composed mostly of cellular material and extracellular polymeric substances (EPS) instead of more easily digestible carbohydrates and fats that are typically found in primary sludge. In an attempt to improve TWAS digestion ...

  • Anaerobic Reactor Design Concepts for the Treatment of Domestic Wastewater

    Since the earlier anaerobic treatment systems, the design concepts were improved from classic reactors like septic tanks and anaerobic ponds, to modern high rate reactor configurations like anaerobic filters, UASB, EGSB, fixed film fluidized bed and expanded bed reactors, and others. In this paper, anaerobic reactors are evaluated considering the historical evolution and types of wastewaters. The ...

  • Winery and distillery wastewater treatment by anaerobic digestion

    ABSTRACTAnaerobic digestion is widely used for wastewater treatment, especially in the food industries. Generally after the anaerobic treatment there is an aerobic post-treatment in order to return the treated water to nature. Several technologies are applied for winery wastewater treatment. They are using free cells or flocs (anaerobic contact digesters, anaerobic sequencing batch reactors and ...

  • Anaerobic treatment of food waste in pilot scale

    For this work, a pilot scale anaerobic digester was used to assess the treatability of food waste from a canteen. The digester was operated for 720 days, and its efficiency in removing organic matter and suspended solids as well as producing biogas were assessed. At the beginning of operation, the digester failed and alkalinity buffering was required until stabilization. A maximum chemical ...

  • New trends in anaerobic treatment: Anaerobic effluent treatment as an integral part of industrial processes

    Anaerobic effluent treatment plants produce valuable energy (biogas) and facilitate recovery of valuable resources. As a result, rather than being regarded as end-of-pipe solution, effluent treatment plants comprising anaerobic treatment, are increasingly been used as an integrated part of the production process of industrial plants. The potential of anaerobic treatment as a more or less ...
