Abstract

Abstract Recently, emerging contaminants such as micropollutants presence in water poses significant challenge to regulators, engineers and scientific community. Micropollutants are introduced in the aquatic environment primarily from discharge of treated effluent from wastewater treatment plants (WWTP). Advanced treatment processes: reverse osmosis, and membrane bioreactor (MBR) can achieve higher and more consistent micropollutants removal. Despite the used technology, the removal of micropollutants depends on phsyico-chemical properties of micropollutants and the treatment conditions. Several advantages make MBR to be recognized as the next generation for wastewater treatment. However, its efficiency is limited due to the presence of micropollutants, causing peculiar membrane fouling. This review compares MBR and conventional activated sludge (CAS) for wastewater treatment and discusses problems arising from the presence of emerging micropollutants, such as the low removal efficiency for certain types of compounds. Mechanisms of micropollutants removal are summarized and related to MBRs operational conditions based on the vast literature existing in this topic. Adsorption and subsequent biodegradation of the micropollutants have been identified as the dominant removal processes, and they are influenced by operational conditions such as solid retention time, biomass concentration, temperature, redox conditions and pH. The review also provides a detailed overview of the effects of micropollutants on microbial activities, since microorganisms respond to environmental stress by producing different polysaccharides and proteins that have a direct impact on membrane fouling. Finally, pertinent issues that must be addressed in order to increase the market share of MBR in the removal of emerging micropollutants are highlighted.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
