Effect of antiscalants during eutectic freeze crystallization of a reverse osmosis retentate
… organic and inorganic contaminants, such as reverse osmosis (RO) retentate brine streams. Since antiscalants are dosed in RO feed streams, these become concentrated in the retentate brine stream and could have an undesirable effect on crystallization kinetics of both ice and salt in EFC. In …

Identification and characterization of aquatic soluble unreactive phosphorus in the hydrosphere with 31-phosphorus Fourier transform nuclear magnetic resonance spectroscopy and high-performance liquid chromatography
… size using a series of ultrafiltration (UF) and reverse osmosis (RO) membranes. The UF membrane pore sizes were 30,000 Da and 1,000 Da while the RO membrane had a 95% NaCl rejection rating. The SUP was analyzed as a function of apparent molecular size and season. In the 30,000 Da retentate, …

Modeling Sensible Heat Driven Direct Contact Membrane Distillation Treatment of Oilfield Produced Water
… of produced water using DCMD alone and using a reverse osmosis-DCMD hybrid system. The largest water recoveries that were energetically favorable (lower energy demand than reverse osmosis) for sensible heat driven DCMD produced water treatment were 0.5% and 0.75% for 1% and 3.5% NaCl feeds, …

Design and application of a bench scale evaporator for the treatment of coal power plant waste water
… (MED) technology for the treatment of Reverse Osmosis (RO) retentate was investigated in this study. An improved bench scale single effect evaporation unit was designed using the Solidworks Simulation Package and appropriate materials. Operating conditions were determined to be 80°C and …
