  • “New” Bioreactor Landfill Technology is 20 Years Old

    Municipal solid waste landfills have gradually evolved to engineered, anaerobic, dry-tomb facilities designed to protect the environment. They present, however, long-term liabilities that require decades of care. Aerobic bioreactor technology achieves rapid stabilization of waste and offers many advantages over conventional sites, including the elimination of methane, a major greenhouse gas. The ...

  • Small-bioreactor platform technology as a municipal wastewater additive treatment

    The bioaugmentation treatment approach presents both an economical and environmentally friendly solution for wastewater treatment. However, the use of exogenous bacterial cultures presents several limitations: negative interaction between microorganisms and adaptation to new physical and chemical composite environment. These selective forces create a significant challenge for the introduced ...

  • Cost comparison of full-scale water reclamation technologies with an emphasis on membrane bioreactors

    The paper assesses the costs of full-scale membrane bioreactors (MBRs). Capital expenditures (CAPEX) and operating expenses (OPEX) of Spanish MBR facilities have been verified and compared to activated sludge plants (CAS) using water reclamation treatment (both conventional and advanced). Spanish MBR facilities require a production of 0.6 to 1.2 kWh per m3, while extended aeration (EA) and ...

  • Future Perspectives in Bioreactor Development

    The paper discusses conversion capacities of both anaerobic and aerobic wastewater treatment systems in relation to growth kinetics, hydrodynamics and biomass concentration. In the current modern anaerobic high-rate reactors the conversion potentials are optimally exploited. This is not yet true for aerobic systems since operation of aerobic systems under conditions of low biomass growth reduces ...

  • Use of a ceramic membrane bioreactor (CMBR) to treat wastewater at Guilin University of Technology

    A ceramic membrane bio-reactor (CMBR) process was first used to treat wastewater collected from a campus of Guilin University of Technology (GUT). A CMBR with a submerged flat-sheet ceramic membrane module was designed for a Qmax of 300 m3/d. With a stable flux at about 33 L/m2 h, the transmembrane pressure was maintained at −10 kPa until the end of the experiment. The results ...

  • Comparison of aerobic granulation and anaerobic membrane bioreactor technologies for winery wastewater treatment

    An anaerobic membrane bioreactor and aerobic granulation technologies were tested at laboratory scale to treat winery wastewater, which is characterised by a high and variable biodegradable organic load. Both technologies have already been tested for alcohol fermentation wastewaters, but there is a lack of data relating to their application to winery wastewater treatment. The anaerobic membrane ...

  • Membrane Bioreactor for Sanitary Landfill

    The Problem The county of Warren NJ owns and operates a sanitary landfill in Oxford Twp, NJ. The facility generates an average of 50,000 gallons per day of leachate, with peaks to 100,000 gallons per day. The facility was discharging to a local POTW from their lagoon, but they were facing requirements for nitrogen removal from the POTW and needed a new system to provide ...

  • Membrane Bioreactor for National Park

    The problem: Assateague Island is a barrier island that stretches from the Eastern shore of Maryland down Atlantic coast to Virginia. The island is a National Park, administered by the National Park Service, under the National Seashore division. Assateague Island is a vital resting and feeding area for birds and also is home to more than 300 wild ponies. The park receives about 1 ...

  • Membrane Bioreactors for RO Pretreatment

    ABSTRACTCurrently, treated municipal wastewater is typically discharged to the environment in most parts of the world. It is, however, a potential water resource from which high quality water for reuse can be produced. Reuse applications include both non-potable applications such as irrigation and production of industrial process water, and indirect potable reuse including aquifer recharge. For ...

  • Pretreatment Requirements for Membrane Bioreactors

    Adequate pretreatment including fine screening is essential to the stable, long-term operation of membrane bioreactors (MBR) used to treat municipal wastewater. The amount of screenings generated by a screen with 1-2 mm size openings ranges between 10-25 dry mg/L. The cost of fine screening represents less than 3% of the total investment cost for a MBR-based wastewater treatment facility. Case ...

  • Airlift bioreactors: Application to wastewater treatment

    After an introductory review, this paper presents a three-phase reactor fluid dynamic model that is used in the development of a generic process for upgrading existing wastewater treatment plants (WWT). The aim is to incorporate nitrification and de-nitrification without additional reactor volume. The core of the process consists of an attached growth airlift reactor (AGAR) in which a biomass ...

  • Membrane Bioreactors – Enviroquip MBR Systems (Retrofit)

    The Leoni Township’s wastewater treatment plant (WWTP) serves thirteen communities across three counties including the Michigan Speedway complex. A moratorium on growth was put in place until capacity and treatment issues with an aging aerated lagoon system could be addressed. In June of this year, construction of a new membrane bioreactor (MBR) ...

  • Evaluation of Novel Operational Strategies for Submerged Membrane Bioreactors

    MBR technology is still expensive to operate when compared to more traditional alternatives. The cost of the membrane and its operation is a significant variable in the overall capital and operational costs of an MBR. A novel dynamic scouring aeration control for membrane bioreactors is proposed in this contribution in order to minimize internal fouling of the membrane and increase the maximum ...

  • Long Term Experience with Hollow Fibre Membrane Bioreactors

    Abstract The membrane bioreactor (MBR) technology has been proven as a single step process to treat wastewater and produce an outstanding effluent quality suitable for reuse, either directly or as a pretreatment to reverse osmosis. While it is relatively simple to combine activated sludge with a membrane separation step, a number of challenges must be met to provide a process suitable for ...
