TLDR
In this article, a review of MBR research efforts in the area of MBRs as well as focus attention to commercial MBR applications in North America is presented. But the primary research focus has been on water filtration MBRs with limited growth in extractive and gas diffusion MBRs which still hold un-tapped potential.About:

Science and technology for water purification in the coming decades
Mark A. Shannon,Paul W. Bohn,Paul W. Bohn,Menachem Elimelech,Menachem Elimelech,John G. Georgiadis,Benito J. Mariñas,Anne M. Mayes,Anne M. Mayes +8 more
TL;DR: Some of the science and technology being developed to improve the disinfection and decontamination of water, as well as efforts to increase water supplies through the safe re-use of wastewater and efficient desalination of sea and brackish water are highlighted.
Journal ArticleDOI
Fouling in membrane bioreactors used in wastewater treatment
TL;DR: In this paper, a review of more than 300 publications on membrane bioreactor fouling is presented, and the authors propose updated definitions of key parameters such as critical and sustainable flux, along with standard methods to determine and measure the different fractions of the biomass.

Algal–bacterial processes for the treatment of hazardous contaminants: A review
Raúl Muñoz,Benoit Guieysse +1 more
TL;DR: It is possible to use microalgae to produce the O(2) required by acclimatized bacteria to biodegrade hazardous pollutants such as polycyclic aromatic hydrocarbons, phenolics, and organic solvents when proper methods for algal selection and cultivation are used.
Journal ArticleDOI
Pharmaceuticals of Emerging Concern in Aquatic Systems: Chemistry, Occurrence, Effects, and Removal Methods.
TL;DR: Adsorption technologies are a low-cost alternative, easily used in developing countries where there is a dearth of advanced technologies, skilled personnel, and available capital, and adsorption appears to be the most broadly feasible pharmaceutical removal method.

Sludge characteristics and their contribution to microfiltration in submerged membrane bioreactors
TL;DR: In this article, the physicochemical and biological characteristics of sludge in submerged membrane bioreactors at various sludge retention times (SRT) and their effect on microfiltration and membrane fouling were investigated.
Journal ArticleDOI
Direct Solid-Liquid Separation Using Hollow Fiber Membrane in an Activated Sludge Aeration Tank
TL;DR: In this paper, a membrane module with a pore size of 0.1 micron was immersed in the aeration tank and treated water was filtered through the membrane by suction.
Journal ArticleDOI
Membrane Bioreactors for Wastewater Treatment
TL;DR: In this paper, the authors cover the subject of membrane bioreactors (MBR) for wastewater treatment, dealing with municipal as well as industrial wastewaters, and discuss the science behind the technology, their design features, operation, applications, advantages, limitations, performance, current research activities and cost.
Journal ArticleDOI
Critical flux determination by the flux-step method in a submerged membrane bioreactor
TL;DR: In this article, a standard flux-step method has been developed for assessing fouling in a membrane bioreactor operating at constant flux, and three parameters based on transmembrane pressure (TMP) were derived to depict fouling behaviour and identify the onset of fouling at the so-called critical flux.

Removal of Estrogens in Municipal Wastewater Treatment under Aerobic and Anaerobic Conditions: Consequences for Plant Optimization
TL;DR: It seems that the substrate present in the raw influent competitively inhibits the degradation of E1 and E2, and these compounds are therefore removed mainly in activated sludge compartments with low substrate loading.
