Membrane bioreactor

It has been found by recent researchers that the dominating fouling agents causing membrane pore blocking are extracellular polymeric substances (EPS) which seem to be produced by micro-organisms which make up the biomass. The other form of fouling caused by cake biomass build up on the membrane sur

The study was undertaken to examine feasibility of biological treating of landfill leachate in anaerobic submerged membrane bioreactor. The aim of the work was to estimate the optimal concentration of leachate in the reactor influent and process parameters on the base of anaerobic digestion efficien

Sludge from five full-scale flat-sheet submerged membrane bioreactors has been analysed with reference to the key biochemical fouling characteristics of soluble microbial product (SMP) and extracted extracellular polymeric substances (EPS). Correlations have been produced between these parameters, a

Especially in the Mediterranean region water is a scarce resource and new approaches to water supply need to be focused. An important contribution can be realised by greywater recycling in decentralised structures. This paper describes the results of a technical feasibility study to treat greywater

A flat type membrane bioreactor (MBR) with a pore size of 0.038 μm and having a total surface area of 540 m2 was operated intermittently for over a year in METU campus at Ankara to treat domestic effluents from dormitories and academic village. At the first stage the MBR plant was operated continuou

The results of an experimental study, developed on a membrane bioreactor/membrane contactor pilot plant, aimed at drinking water denitrification are presented and discussed. In the adopted configuration the water, contaminated by nitrates, flows inside the fibres of a membrane unit. Due to the exist

High strength industrial wastewater was treated using a pilot scale submerged membrane bioreactor (MBR). The MBR was maintained at higher sludge concentration of 14,500 mg/l at prolonged sludge retention time (SRT). It was found that the prolonged SRT MBR could achieve both COD and TOC overall remov

One of the most crucial and difficult elements of the bioprocess is its ability to separate between the biosolids and the liquid effluent phase. The objectives of this study were to evaluate practical possibilities to upgrade existing wastewater treatment facilities by operating aerobic treatment ba

Generally, membrane biofilm have been believed to be minimized during the operation of membrane bioreactor (MBR) for wastewater treatment and reuse. In this study, positive roles of membrane biofilm in the intermittently aerated MBR system were highlighted. During the long-term operation using real

A nonwoven fabric module was utilized as a solid–liquid separation medium in a membrane bioreactor (MBR) for treating wastewater. The experimental results indicated that nonwoven fabrics had lower filtration resistance than microporous membranes in MBR applications. The optimal aeration intensity wa
