Abstract

To remove total dissolved solid (TDS) from wastewater, a carbon membrane system was prepared, using carbon membranes made from conductive activated carbon and poly(vinylidene fluoride) (PVDF). Using 100 ppm aqueous solutions of NaCl, $Na_2SO_4,\;MgCl_2,\;MgSO_4$, the basic properties of the carbon membranes used were studied. For the treatment of the real dye wastewater supplied from Kyungin Corp., a pilot scale carbon membrane system was also prepared, which was consisted of 240 plies of carbon membranes of $20cm{\times}20cm$ (length${\times}$width). Using the real wastewater with different TDS such as 941, 2050, 2810, 3830, 4960, 6030 ppm, prepared by the dilution of the original wastewater with pure water, the performance of the pilot scale carbon membrane system was studied. The effect of the operational conditions was studied.

전도성 활성탄소와 폴리비닐리덴플로라이드(PVDF)를 이용하여 제조된 탄소막을 이용하여 폐수의 Total dissolved Solid (TDS)를 제거할 수 있는 탄소막 시스템을 제조하였다. 100 ppm의 NaCl, $Na_2SO_4,\;MgCl_2,\;MgSO_4$수용액을 이용하여 탄소막의 기본 특성을 알아보았으며, (주)경인양행의 실제폐수인 염료폐수로부터 TDS를 제거하는 실험을 위하여 가로 ${\times}$ 세로가 각각 20cm인 탄소막 240장으로 구성된 Pilot 규모의 탄소막 시스템을 구성하였다. 원폐수를 초순수로 적절히 희석하여 제조된 6가지의 TDS (941, 2050, 2810, 3830, 4960, 6030 ppm)를 지닌 실제폐수를 이용하여 제조된 Pilot규모의 탄소막 시스템의 TDS 제거성능을 알아보았으며, 여러 운전조건에 따른 탄소막 시스템의 분리특성을 알아보았다.
