Dye removal from a real bakers’ yeast production wastewater by PAN nanofiltration membrane

The colored industrial wastewaters are typically categorized into problematic wastewaters to treat, therefore in the present study poly acrylonitrile (PAN) nanofiltration membrane has been used in a dead-end set-up for dye rejection from a real baker’s yeast production wastewater. Also, the effect of three operating variables including operating pressure, COD concentration, and pH on dye removal efficiency was investigated. From the obtained results, lower operating pressure and COD concentration alongside higher pH led to dye rejection more than ۹۰% by applying PAN nanofiltration membrane.
