| Summary: | Dye removal from effluents of textile industries of Iran was investigated through biodegradabilitymethod and membrane technology . Basic, reactive,disperse and acidic dyes were selected, based onusage rate in Iran. The Zahen - Welenze method (ISO 9888) was applied to study the biodegradabilityof dyes. Results showed the final COD and dye removal (%R) as (%61,% 57), (%73, %76), (%25, %14),and (%32, %8) for acidic, basic, reactive and disperse dyes, respectively. Also, the ADMI value ininfluent and effluent wastewater were (4063, 1768), (271, 111), (2359, 2211) and (2073, 966), respectivelyfor 4 types of dyes. Four types of selected membranes were: (PPT) NF (MWCO= 300Da), (PWB) NF(MWCO= 600Da), (TFC) RO (MWCO=50Da) and UF (MWCO= 20KDa). Results with membranesfor maximum %R were %93, %76 and > %95, with NF300, NF600 and RO (for all types of dyes), respectively, demonstrating the high removal potential of reverse osmosis membrane. |
