“…To date, AnMBR pilot-plants have been used for the treatment of different wastewaters with a high content of organic matter, such as that from food processing and industrial use (e.g. [51,77]), the pulp and paper industry [52,[78][79][80], textile production [81,82] and polymer synthesis [83]. Most recently, laboratoryand pilot-scale AnMBR plants have been used to treat different food processing wastewater, e.g.…”

Anaerobic membrane bioreactors (AnMBRs) are increasingly being used in industrial wastewater treatment as the technology represents a cost-effective alternative to that based on aerobic processes. Not only AnMBRs are highly efficient in reducing chemical oxygen demand but the organic matter removed is transformed into a useful energy source-biogas. AnMBRs produce effluent that is free of solids and pathogens and rich in nutrients, while occupying a small footprint. As the membrane retains biomass, AnMBRs enhance performance when dealing with inhibitory or toxic substrates, typical of industrial wastewaters. Some drawbacks remain, however, including membrane fouling and its associated effects as well as poor efficiency at lower temperature (AnMBRs are usually operated at mesophilic or thermophilic conditions). Further research is needed on lowering hydraulic retention time, removal of nutrients, removal of specific micro-pollutants, establishing quantitative mass and energy/economic balances and inclusion of efficient dissolved methane recovery. In this mini review, the applications, limitations and perspectives of AnMBRs are summarized and evaluated with an emphasis on industrial wastewater treatment. Moreover, the AnMBR is compared with other wastewater treatment technologies presently available.

“…These kinds of compounds are pollutants of water and are dangerous for the human health and the environment. Attempts for removal of these compounds have been made in anaerobic conditions, but results have been poor (Dangcong & Xingwen 1994;Araya et al 1999Araya et al , 2000. It is said that the main limiting step is the inhibition of the methanogenic activity produced by the concentration of polymeric resins compounds (PRC) and the accumulation of intermediates (Stuckey et al 1980;Grbić -Galić et al 1990;Demirer & Speece 1999).…”

The biological elimination of polymeric resins compounds (PRC) such as acrylic acid and their esters, vinyl acetate and styrene under methanogenic and oxygen-limited methanogenesis conditions was evaluated. Two UASB reactors (A and B) were used and the removal of the organic matter was studied in four stages. Reactor A was used as methanogenic control during the study. Initially both reactors were operated under methanogenic conditions. From the second stage reactor B was fed with 0.6 and 1 mg/L.d of oxygen (O2). Reactor A had diminution in chemical oxygen demand (COD) removal efficiency from 75+/-4% to 37+/-5%, by the increase of PRC loading rate from 750 to 1125 mg COD/L.d. In this reactor there was no styrene elimination. In reactor B the COD removal efficiency was between 73+/-5% and 80+/-2%, even with the addition of O2 and increase of the PRC loading rate, owing to oxygen being used in the partial oxidation of these compounds. In this reactor the yields were modified from 0.56 to 0.40 for CH4 and from 0.31 to 0.60 for CO2. The O2 in low concentrations increased 40.7% the consumption rates of acrylic acid, methyl acrylate and vinyl acetate, allowing styrene consumption with a rate of 0.103 g/L.d. Batch cultures demonstrated that under methanogenic and oxygen-limited methanogenesis conditions, the glucose was not used as an electron acceptor in the elimination of PRC.

Worldwide increasing energy problems prompts researchers to find new and renewable energy sources. There are many new studies on energy investigation using different materials and technology. These studies were quite important for continuing development, comfortable life and industrial improvement. This investigation considers the removal of volatile organic compounds frequently found in many wastewaters and methane production following the wastewater treatment. The study was performed on the up flow anaerobic condition sludge blanket reactors. Used volatile organic compounds are trichloroethylene, chloroform, dichloromethane, and TCE. Removal ratio of these compounds were 87.8% trichloroethylene, 96.5% chloroform, 67.1% dichloromethane, and 97.3% tetrachlorethylene. Methane ratios in the gas production were 67.1% for TCE, 72.4% for chloroform, 69.6% dichloromethane and 69.8% tetrachlorethylene.
