Fate and impact of organics in an immersed membrane bioreactor applied to brine denitrification and ion exchange regeneration.
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:

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.

Adaptive modifications in membranes of halotolerant and halophilic microorganisms
TL;DR: A review of various strategies of haloadaptation of membrane proteins and lipids by halotolerant and halophilic microorganisms can be found in this paper, where moderate and extreme halophiles adapt their membrane lipid composition by increasing the proportion of anionic lipids, often phosphatidyl glycerol and/or glycolipids.

Selection of anionic exchange resins for removal of natural organic matter (NOM) fractions
Emile Cornelissen,N Moreau,W.G. Siegers,AJ Abrahamse,Luuk C. Rietveld,A. Grefte,M Dignum,Gary L. Amy,Gary L. Amy,L.P. Wessels +9 more
TL;DR: The removal of NOM fractions, specifically humic substances, increased with an increase in water content of the investigated IEX resins and with a decrease in resin size, and the best-performing Iex resins consisted of the smallest resin and/or those with the highest water content.
