Efficacy of Ultraviolet Light and Antimicrobials to Reduce Listeria monocytogenes in Chill Brines
Chill brines used in ready-to-eat meat processing may be an important source of post-processing contamination by Listeria monocytogenes. The purpose of this study was to determine the efficacy of ultraviolet light (UV) in combination with antimicrobials to reduce L. monocytogenes in fresh and used …

Chloride Salts Removal by non Planted Constructed Wetlands Receiving Synthetic Brines from Belle Plaine Potash Mining
Four pilot-scale constructed wetlands (CWs) were employed to study the fate and transport of the two dominant chloride salts (NaCl and KCl) receiving the synthetic brine. The characteristics of the brine solution are made up with a 10:1 concentration ratio between NaCl and KCl based on data …

Electrokinetic and Chemical Aspects of Transport of Chloride Brines Through Compacted Smectite Layers at Elevated Pressures (Electroosmosis, Streaming, Conductivity)
Solutions of NaCl and NaCl-CaCl were forced through clay plugs made by compacting the 0.2 to 2.0 micron size fraction of Cheto montmorillonite. The concentration of NaCl solution was either 1.10 m or 1.087 m, and that of NaCl-CaCl(,2) solution was 0.92 m in NaCl and 0.075 m in CaCl(,2). Clay plug …

Lithium Transport in Monovalent Selective Electrodialysis: Effect of Brine Salinity, Acidity and Composition
… in lithium extraction from salt lake brines. MSED of multi-component brines containing more coexisting ions is shown to be less effective than brines with only one coexisting cation. The study shows that pH 7 had significantly higher separation coefficient than lower pH without …

Development of a brine treatment protocol using Eutectic Freeze Crystallization
Hypersaline inorganic brines are generated from many global mining operations and the volume of these brines is increasing at an exponential rate. The environment and water resources in the vicinity of these mining operations are at a risk of being polluted as a result of this increase in brine …

Impurities in crystals formed by eutectic freeze crystallization
… developed for the treatment of industrial waste brines; Eutectic Freeze Crystallization (EFC), can potentially separate these into pure water and its major constituent salts, which can be reused or sold. The feasibility of this technology is heavily invested in its capacity to produce pure salts. …
