Salt

In vacuum salt production sulfate is an important impurity, but it is also used to remove other cationic impurities from the raw brine. Removal of excess sulfate is currently done by purging salt crystallizer mother liquor from the brine plant, or crystallizing sodium sulfate through evaporative or

The separation of volatile organic compounds (VOCs) from chemical waste streams containing salts is an interesting pervaporation (PV) application for recovery purposes. In this study, the separation of n -butanol (n BuOH) by PV was investigated, and the influence of temperature, membrane choice, fee

In this study the effects of operating parameters on the ultrafiltration of metal working fluids were considered and the optimum conditions for filtration were estimated. In order to reduce the number of experiments an experimental design method (Taguchi) was applied. Seven parameters including pH,
