TLDR
It was concluded that a denitrification MBR was an appropriate technology for IEX spent brine recovery and reuse and compared to that determined when using freshly produced brine for regeneration.About:

Fouling Issues in Membrane Bioreactors (MBRs) for Wastewater Treatment: Major Mechanisms, Prevention and Control Strategies
TL;DR: In this article, the authors present the fundamentals of fouling issues in membrane separations, with specific regard to membrane fouling in Membrane Bioreactors and the most frequently applied preventive-control strategies.

Photocatalytic reduction of nitrate using titanium dioxide for regeneration of ion exchange brine.
TL;DR: This work presents a strategy to photocatalytically reduce nitrate in IX brine, thereby extending the use of the brine and investigating the impact of residual FA for brine reuse.

Brine Effluents: Characteristics, Environmental Impacts, and Their Handling
TL;DR: In this paper, an overview of different types of brine effluents, their sources and characteristics are discussed, as well as impacts of brines on the environment and management options related to their characteristics.
Journal ArticleDOI
Biogas upgrading by chemical absorption using ammonia rich absorbents derived from wastewater.
TL;DR: This demonstrates that ammonia rich wastewaters can facilitate chemically enhanced CO2 separation which eliminates the need for costly exogenic chemicals or complex chemical handling which are critical barriers to implementation of chemical absorption.

Journal ArticleDOI
A unified theory for extracellular polymeric substances, soluble microbial products, and active and inert biomass.
TL;DR: A unified theory shows that the apparently distinct products from the SMP and EPS schools overlap each other, and shows that Soluble EPS is actually SMP, or the sum of UAP and BAP.
Journal ArticleDOI
Microbial biomass measured as total lipid phosphate in soils of different organic content
TL;DR: In this article, the use of total lipid phosphate as a measure of biomass was evaluated in soils with different organic matter content, and the two digestion methods showed a good linear correlation (r2 = 0.991).
Journal ArticleDOI
The influence of key chemical constituents in activated sludge on surface and flocculating properties
TL;DR: The results reveal that the quality and quantity of the polymeric compounds within the sludge flocs is more informative, with respect to understanding the mechanisms involved in flocculation, than if only the extracted EPS are considered.

Phospholipid Ester-linked Fatty Acid Biomarkers of Acetate-oxidizing Sulphate-reducers and Other Sulphide-forming Bacteria
TL;DR: High levels of cyclopropyl fatty acids, including two isomers of both methylenehexadecanoic and methyleneheptadecanoics acids, were also characteristic of Desulfobacter spp.
Journal ArticleDOI
Factors affecting the membrane performance in submerged membrane bioreactors
TL;DR: In this paper, the authors describe the rise in transmembrane pressure (TMP) as a three-stage process, which occurs in a period of a few hours and involves abrupt TMP rise due to pore blockage and closure.
