Nation’s Largest Tank Barge Company case study
The Problem: The Nation’s largest tank barge company is a centralized treatment facility that receives oily wastewater from barges and ships that transport oil and petroleum products. The wastewater is highly loaded with BOD, COD, TSS and oil and they were seeking a direct discharge permit. The Solution: In 2010, Ecolab partnered with bioprocessH2O to provide a fully integrated API ...

What is the Membrane Bioreactor Tank?
MBR membrane bioreactor is a new type of water treatment technology that combines membrane separation technology and activated sludge biotechnology. The MBR membrane module is placed in the membrane tank to replace the role of the secondary sedimentation tank in traditional water treatment. The treatment method is more efficient, and the effluent quality is better. In the operation of the entire ...

Characterisation of RO fouling in an integrated MBR/RO system for wastewater reuse
Membrane filtration has gradually gained acceptance as the preferred pre-treatment for reverse osmosis (RO). In this paper, an integrated membrane bioreactor (MBR)/RO system for wastewater reuse treating real sewage water has been evaluated and the RO fouling has been characterised. The MBR achieved low values of organic matter, total nitrogen, PO43−, total organic carbon, turbidity and ...

Beyond the barriers of water reuse
Water reuse may be the moment’s most talked about treatment industry topic. It’s no wonder that as drought persists in regions throughout the world without sign of subsiding, questions about how we can make the most of our water are being asked. An answer can be found in the ways that we apply membrane bioreactor (MBR) technology. As one of the most central components for water ...

Elimination of trace organics in an MBR/RO system for water reuse
An intensive programme for detection of trace organics was performed in a membrane bioreactor (MBR) plant in Almuñécar (south of Spain) over 1 year. The compounds investigated included 15 pharmaceutically active compounds, 12 polycyclic aromatic hydrocarbons and eight other compounds (nonylphenols, linear alkylbenzene sulphonates and phthalates). The MBR operated with two lines in ...

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 the required treatment. ...

Treatment of hospital wastewater effluent by nanofiltration and reverse osmosis
Considerable concern exists regarding the appearance and effects of trace and ultra trace pollutants in the aquatic environment. In this context, it is necessary to identify relevant hot spot wastewater – such as hospital wastewater – and to implement specific wastewater treatment solutions. Membrane bioreactor (MBR) technology seems to be a suitable pre-treatment approach for the subsequent ...

Membane bioreactors: is submerged best?
Untitled Document The energy and space-saving characteristics of submerged membrane bioreactors have prompted many to view them as the most efficient and cost effective wastewater treatment technology. But there are equally viable alternatives, argues Ronald van ‘t Oever of Netherlands-based X-Flow. A membrane bioreactor (MBR) is a compact-built purification system combining ...

An evaluation of MBR and conventional pretreatment for reverse osmosis for water reclamation
Two wastewater polishing systems were compared in terms of their ability to protect downstream reverse osmosis (RO) processes. A conventional full-scale wastewater treatment system with primary and secondary treatment followed by rotating biological contactors (RBC) and sand filtration were compared in a side-by-side study with a pilot-scale membrane bioreactor (MBR). Effluent from the two ...

Dissolved air flotation separation for pretreatment of membrane bioreactor in domestic wastewater treatment
Due to requiring higher water quality standards over time, new technologies are being employed for wastewater treatment. Dissolved air flotation (DAF) and membrane bioreactor (MBR) technologies are widely employed as new technologies in wastewater treatment. DAF is used due to its excellent separation capability of suspended solids as well as oily material. MBR is used because it may provide a ...

How Can You Manage and Treat Industrial Wastewater?
Download The Guide To Water Filtration In Industrial Processes Modern membrane technologies allow for the treatment of industrial wastewater solutions to be managed by an all in one system. Dependent on the water issue and the quality of water you want to achieve, multiple units can be combined to create a bespoke water solution for your industrial process. Industrial wastewater is mainly ...

Sewer mining to supplement blackwater flow in a commercial high-rise Australia-Sydney case study
Project Background or Rationale Australia’s warm climate and habitual droughts have resulted in innovative water conservation practices in commercial developments, such as 1 Bligh Street in Sydney. Commissioned in May 2011, the highly acclaimed 29 story office tower overlooking the Sydney Harbor captures nearly 100 percent of its wastewater and reuses it in the building. By recycling the ...

What is Industrial Wastewater Treatment - and who needs it?
Every business that makes something on an industrial scale produces wastewater, sometimes at millions of litres daily. All that wastewater must go somewhere, but contamination can make reuse and discharge impossible. The simple solution is industrial wastewater treatment, either on-site or off-site, to transform it into a cleaner product suitable for discharge or reuse. But who needs these ...

Membrane bioreactor application within the treatment of high-strength textile effluent
A pilot-scale dual-stage membrane bioreactor (dsMBR) incorporating two ultra-filtration (UF) side-stream membrane modules was designed, constructed, operated and evaluated on-site for treating high-strength textile effluent. The effluent stream was characterised by a COD range of between 45 to 2,820 mg/L and an average BOD of 192.5 mg/L. The dsMBR achieved an average COD reduction of 75% with a ...

Novel pretreatment enables performance of MBR installed to treat oily wastewater
Abstract Two new integrated systems processes, gas-energy-mixing (GEM) flotation – electrochemical catalytic oxidation (ECO) – membrane bioreactor (MBR) and ultra-filtration (UF) – ECO – MBR, were tested in industrial-scale pilots of 200L/h to 3000L/h for the treatment and reuse of steel mill cold-rolling emulsion wastewater. The operation parameters and mechanisms of each ...
