Abstract:

The aim of this study is to evaluate and compare the performance of the three different reverse osmosis membranes in the processing of real textile industry waste. The study used real-scale waste treatment facility output waters that cleanse textile industry waste, and membrane performance was evaluated in terms of COI, color, conductivity and membrane flow. The study tested the B400FR, B400HR and BW30 membranes with cross-flow filtration arrangements in 10 hour filtration studies. In the same pressure study, the highest permeability value (3.45±0.12 LMH/bar) and the lowest flow loss (69) were given to the B400HR membrane, while the highest flow decrease (82) was observed in the BW30 membrane. The waste used has 4570±130 μS/cm conductivity, 188±2 Pt-Co color and 35±2 COI concentrations, the flow COI value for all the tested membranes is reduced to below 10 mg/L, and the B400FR membrane has shown the best COI discharge performance. The average conductivity output is above the value of 92% for all membranes, with the value of 96, 94 and 92% for B400FR, B400HR and BW30 respectively. Similarly, the color discharge for all membranes occurred above 99%. With the results obtained, the reuse of the water is possible in the same industry.
