an innovative method based on the membrane bioreactor (mbr) technology was developed as a potential remedy for the water shortage. mbrs attracted much attention in the field of wastewater treatment and reuse. it is reported from many researchers that membrane bioreactor technology is feasible and an efficient method for the treatment of wastewater. however, mbrs are faced to membrane fouling whic...

The long-term performance of a submerged membrane fungi reactor was observed while a synthetic textile wastewater containing either or both of the two structurally different azo dyes was continuously fed. Compared to the Acid Orange II dye (simpler structure), higher biosorption but slower biodegradation of the polymeric dye (Poly S119) was observed in sterile batch tests. In the membrane biore...

Abstract The fish canning industries produce a large amount of wastewater. high-strength wastewater from processing industry is great concern worldwide. This type rich in organic matter and has high total dissolved solids (TDS). elimination salts usually expensive and, on the other hand, salinity seasonal variation effluent characteristics make removal difficult using only biological process. F...

A combined approach of treating domestic wastewater using microbial fuel cell (MFC) and membrane bioreactor (MBR) has been developed as a promising and reliable technology of wastewater treatment. Treatment of wastewater in a single stage MFC has limitation to achieve the required treatment efficiency and utilize the effluent for irrigation or any other possible reuse without further treatment....

Two different membrane treatment scenarios have been applied for of the high strength dark color alkaloid industry wastewater. A bioreactor (MBR) system having separately UF and MF membranes was operated with raw wastewater (scenario-A) anaerobically pre-treated (scenario-B). NF 270, 90 RO (XLE) were used as a polish-ing step at two recovery ratios 50% 75% both scenarios. In scenario-A, COD re-...

This preliminary study was aimed at evaluating the feasibility to produce biopolymers (BP) from citrus wastewater by mixed microbial culture in an anaerobic/aerobic membrane bioreactor (A/O-MBR). The activated sludge of A/O-MBR successfully enriched microorganisms having a good capacity producing intracellular biopolymers. production BP found be about 0.55 mgCOD mgCOD−1 using pure acetate conce...

A bioreactor equipped with hollow fiber microfiltration membranes was applied for wastewater treatment. Removal of chemical oxygen demand (COD) and biochemical oxygen demand (BOD5) was investigated. The experimental setup consisted of influent and effluent tanks, and membrane modules using Polyvinyl Di–Fluoride (PVDF) hollow fibers. The operation program included suction and backwash...

The development and application of a membrane bioreactor (MBR) for fullscale municipal wastewater treatment is the most important recent technological advance in terms of biological wastewater treatment. The MBR is a suspended growth-activated sludge system that utilizes microporous membranes for solid/liquid separation instead of secondary clarifiers. It represents a decisive step forward conc...

The technique that employs flash freezing and environmental scanning electron microscopy (ESEM) was utilised for detailed investigation of the fouling materials in a membrane bioreactor (MBR). The method involves the flash freezing of a wet sample in liquid nitrogen for 10s to preserve its structure for direct ESEM observation with a high image resolution. ESEM images show that the sludge cake ...
