EFFICIENCY EVALUATION OF TEXTILE BASIC DYE REMOVA L FROM WATER BY NANOFILTRATION

Abstract
Nanofiltration, widely developed over the past decade, is a promising technology for the treatment of organic and inorganic pollutants in surface and groundwater resources. The aim of the present research was to study the efficiency of textile dyes removal by a commercial nanofilter NF90 (Dow-Film Tec). Dye rejection was studied using basic dye (Basic Chrysoidine Cryst Yellow Gold 0.4%) with its relevant additive. Experiments were continued until the fouling time of the membrane. Each experiment was repeated after washing to evaluate the efficiency of the washing process. Results showed that the values of color removal were 97.98 % for the simulated textile wastewater containing basic dye. The membrane was sensitive to fouling since most of dyes were used for polyamide textile dyeing. Washing the membrane with a solution including NaOH (pH=12) and HCl (pH=2) showed its efficiency to solve the fouling problem. The filtration process was efficient and promising for reusing wastewater in this industry.
