  • 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 ...

  • 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 ...

  • 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 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Application of membrane technology in wastewater

    The City of Rio Rancho is the fastest growing and fourth largest city in New Mexico. The City currently relies heavily on groundwater for water supplies. To sustain its long-term water needs, the City has undertaken a feasibility study to develop a Water Reuse Strategy that will significantly expand the use of reclaimed water, reduce groundwater withdrawals, and provide advanced ...

  • THIOPAQ® technology for the mining and metallurgical industries

    Abstract THIOPAQ® technology, developed and marketed by PAQUES Bio Systems B.V. in Balk, Netherlands, was first applied commercially in 1992 for the treatment of contaminated groundwater at the Budelco zinc refinery in the Netherlands. In its most basic form, a THIOPAQ® system essentially consists of two biological process stages in series: (i) sulfate reduction to sulfide (anaerobic stage), ...

  • 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 Bioreactor for Water Mining in New York City

    The Facility The Helena, which opened in late 2005, is an apartment building that offers more than amenities, views, and nice finishes. Behind the $100 million tower’s gleaming glass and metal skin is a serious high-performance building. Its owner and designers say the Helena will annually use 65 percent of the energy and one-third of the potable water of comparable ...
