Tabriz Oil Refinery Uses MBR to Contain Wastewater

TEHRAN May 31(Shana)--Tabriz oil refinery and Sahand University of Technology will cooperate with each other to protect environment by using membrane bioreactor (MBR) technology.

Decontamination and preventing the negative impact of industrial waste water is the main aim of the scientific study.

Tarbirz oil refinery has sent a sample of its waste water for test to Sahand University of Technology.  

When used with domestic wastewater, MBR processes can produce effluent of high quality enough to be discharged to coastal, surface or brackish waterways or to be reclaimed for urban irrigation. Other advantages of MBRs over conventional processes include small footprint, easy retrofit and upgrade of old wastewater treatment plants.

It is possible to operate MBR processes at higher mixed liquor suspended solids (MLSS) concentrations compared to conventional settlement separation systems, thus reducing the reactor volume to achieve the same loading rate.

Two MBR configurations exist: internal/submerged, where the membranes are immersed in and integral to the biological reactor; and external/sidestream, where membranes are a separate unit process requiring an intermediate pumping step.

Recent technical innovation and significant membrane cost reduction have enabled MBRs to become an established process option to treat wastewaters.

As a result, the MBR process has now become an attractive option for the treatment and reuse of industrial and municipal wastewaters, as evidenced by their constantly rising numbers and capacity. The current MBR market has been estimated to value around US$216 million in 2006 and to rise to US$363 million by 2010.
