Iodide recovery from thin film transistor liquid crystal display plants by using potassium hydroxide - driven forward osmosis
For the first time, KOH in the waste stream of a thin film transistor liquid crystal displays (TFT-LCD) plant was utilized as a draw solution to recover iodide in the waste stream through forward osmosis (FO). In long-term operation, the pressure-retarded osmosis mode provided concentration efficien...
