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.

Polysaccharides and sticky membrane surfaces: critical ionic effects
Brian P. Frank,Georges Belfort +1 more
TL;DR: It is demonstrated that, under physiological and marine conditions, critical surface tension correlates with adhesion, and that during synthetic membrane filtration with solutions containing biological molecules, such as polysaccharides, proteins and nucleic acids at relatively low ionic strength, wettability correlates inversely withAdhesion.

Nitrate reduction with Halomonas campisalis. Kinetics of denitrification at pH 9 and 12.5% NaCl.
TL;DR: Halomonas campisalis (ATCC #700597) was shown to completely reduce nitrate at 125 g/L NaCl and pH 9.5, and the use of halophiles to selectively remove nitrate from these brines may represent a viable treatment option.
