| Abstract |
The separation of dilute hazardous organics was accomplished through this project utilizing thin-film composite aromatic polyamide membranes. This technique offers advantages in terms of high solute separation at low pressures (1-2 MPa) and broad pH operating ranges (pH 2 to 12). The synthetic organic waste solutions used in the study include: poly aromatic hydrocarbons (PAH), phenol, chlorophenols, nitrophenols, and chlorobenzenes. The actual organic waste solution was obtained from the site of a former wood treatment processing plant in Texas and was known to contain chlorophenols. The membrane showed excellent stability over long periods of time. Standard NaCl rejections were 97-99% and the average pure water flux at 2.068 MPa was about 14 times 10 to the minus 4 power (cu. cm./sq. cm.s). |
