Removal of Acid Blue Dye from Industrial Wastewater by using Reverse Osmosis Technology

Abstract

This study is devoted to assess the removal of acid blue dye from simulated industrial wastewater by using integrated membrane system of microfiltration to remove the suspended solid followed by reverse osmosis filter (RO). The dye is currently used in Al-Kut textile factory, Wassit Governorate, Iraq. The effect of RO systems on percentage removal of dye and permeate flux were studied under different operating conditions, such as applied pressure (5-10 bar), initial dye concentration (25-100 mg/l) to satisfy the concentration in mentioned factory , at constant pH and room temperature.
The results showed that the removal effcienciey were increase with increasing the pressure up to ( 98% ) and the initial concentration of the acid blue dye during 90 min of the operation. While, the permeate flux increases with increasing pressure, Also, the permeate flux was inversely proportional to the dye concentration in the system.
The total dissolved solids (TDS) was removed with high efficiency reaching nearly 100% by using RO membrane.
