In this study, a PES/SiO2 based thin film composite (TFC) hollow fiber membrane (HFM) was prepared for the oilfield produced water desalination with low-pressure nanofiltration process. The effects of operating parameters including pressure, salt concentration and time, on the salt rejection were investigated. The results showed that the salt rejection increased linearly with an increase in operating...
The objective of this study was to develop a pH sensor for monitoring hydrogen ion activity in situ in oilfield-produced water under subsurface conditions. An iridium oxide film was prepared, and the performance of the iridium oxide film was evaluated in produced water using a series of high salinities, temperatures, and pressures. Scanning electron microscopy (SEM), energy-dispersive X-ray...
