This study demonstrated the feasibility of implementing of MBR in pharmaceutical wastewater independently, and concluded different applications of MBR in industries. Membrane bioreactor (MBR) technology was a new wastewater treatment technology with a combination of membrane separation technology and biological treatment technology, which had unique advantages on pharmaceutical wastewater treat...
A membrane bioreactor (MBR) and an activated sludge process (ASP) were operated side by side to evaluate the change of sludge supernatant characteristics and the evolution of the sludge fouling propensity. The MBR sludge had a higher organic concentration and more biopolymer clusters (BPC) in the supernatant compared with ASP. BPC increased in both concentration and size in the MBR. The results...
یکی از جدیدترین تکنولوژی های تصفیه فاضلاب ، ترکیب فرآیندهای بیولوژیکی با جداسازی غشایی می باشد که به سرعت در این صنعت درحال رشد است . فرایند mbr(بایو راکتور های غشایی) با ادغام واحدهای ته نشینی ، هوادهی و فیلتراسیون در یک راکتور، جایگزین فرآیند های تصفیه متعارف شده است که برای انواع فاضلاب ها قابل کاربرد است و راندمان مناسبی در حذف آلودگی ها دارد اما یکی از معضلات اساسی آن،گرفتگی غشا می باشد که...
A recognition site for benzodiazepines structurally different from that linked to the gamma-aminobutyric acid receptor subtype A or the "central type" benzodiazepine receptor has been located mainly in the outer membranes of mitochondria and designated mitochondrial benzodiazepine receptor (MBR). A putative endogenous ligand for MBR is the peptide, diazepam binding inhibitor (DBI), which inhibi...
ON THE DISTRIBUTION OF RANKED HEIGHTS OF EXCURSIONS OF A BROWNIAN BRIDGE1 By Jim Pitman and Marc Yor
The distribution of the sequence of ranked maximum and minimum values attained during excursions of a standard Brownian bridge Bbr t 0 ≤ t ≤ 1 is described. The height Mbr+ j of the jth highest maximum over a positive excursion of the bridge has the same distribution as Mbr+ 1 /j, where the distribution of Mbr+ 1 = sup0≤t≤1 Bbr t is given by Lévy’s formula P Mbr+ 1 > x = e−2x 2 . The probabilit...
Background B-cell lymphomas harboring the 8q24/MYC plus 18q21/BCL2 translocations are now referred to as high grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements (HGBL-MBR). Although HGBL-MBR is frequently found in cases with diffuse large B-cell lymphoma or Burkitt lymphoma-like B-cell lymphoma, acute lymphoblastic leukemia (ALL)-like disease of HGBL-MBR (AL-HGBL-MBR) has been r...
در طول سه دهه اخیر زیستراکتورهای غشایی (MBR) برای تصفیه انواع مختلف فاضلاب شهری و صنعتی کاربرد گستردهای یافتهاند. اما، گرفتگی غشاء و هزینههای هنگفت غشاء موانع اصلی برای کاربرد گستردهتر MBRها بهشمار میآیند. از اینرو، درک بهتر از گرفتگی غشاء نه تنها میتواند کلید حل مشکلات باشد، بلکه یکی از عوامل اصلی استفاده هرچه بیشتر از فرایندهای غشایی در آینده بهحساب میآید. در طول دهه اخیر، تحق...
The most effective soil fumigant for the past 40 years for preplant chemical control of nematodes, weeds, and fungal pathogens in Florida vegetable production has been methyl bromide (MBr). Unfortunately, MBr has been implicated in depletion of stratospheric ozone, and is slated to be banned in the United States. A possible alternative replacement to MBr is metam sodium (MS, sodium N-methyl dit...
A novel quorum quenching (QQ) strain, Acinetobacter guillouiae ST01, was isolated from a full-scale membrane bioreactor (MBR) and characterized for its QQ activities. Batch reactor studies at lab-scale showed that A. ST01 exhibited higher activity against acyl homoserine lactones (AHLs) with an oxo group compared to those without group. The organism then inoculated (10%) in MBR (Q-MBR) treating...
The removal of trace organics by a membrane bioreactor-granular activated carbon (MBR-GAC) integrated system were investigated. The results confirmed that MBR treatment can be effective for the removal of hydrophobic (log D>3.2) and readily biodegradable trace organics. The data also highlighted the limitation of MBR in removing hydrophilic and persistent compounds (e.g. carbamazepine, diclofen...
