Nanofiltration process on dye removal from simulated textile wastewater
Dyestuffs removal from industrial wastewater requires special advanced technologies, since dyes are usually difficult to remove by biological methods. In this study nanofiltration process was used for removal of different dyestuffs from solutions. The rate of dye removal by spiral wound nanofiltrati...

| description | Dyestuffs removal from industrial wastewater requires special advanced
technologies, since dyes are usually difficult to remove by biological
methods. In this study nanofiltration process was used for removal of
different dyestuffs from solutions. The rate of dye removal by spiral
wound nanofiltration membrane in film thin composite MWCO=90 Dalton,
was evaluated for four classes of dyes acidic, disperse, reactive and
direct in red and blue dyes medium. Dye absorbance was measured by
spectrophotometric method (2120 Standard Method 1998). Effects of feed
concentration, pressure and total dissolved solids concentration were
also studied. Results showed that increasing dye concentration lead to
higher color removal up to 98 % and at different pressures for acidic
and reactive blue were up to 99.7 %. Different types of dyes had no
effect on dye removal and permeate flux. During 2 h.of the operation
time, permeate flux decline was increased. Permeate fluxes for
different types of red dyes were from 16.6 to 12.6 (L/m2/h.) and for
blue dyes were from 16.6 to 10.45 (L/m2/h.). Presence of sodium
chloride in dye solutions increased dye rejections nearby 100 %.
Chemical oxygen demand removal efficiencies for reactive blue, disperse
blue, direct and disperse red dyes were also approximately 100 %. |
