Abstract:

© 2019 Elsevier Ltd This research investigated the removal mechanism of algae metabolized materials (geosmin, 2-methylisoborneol (2-MIB), and microcystin-leucine arginine (MC-LR)) according to the naturally occurring operation factors such as temperature (10, 20 and 30 °C), transmembrane temperature (20 °C: 10 vs. 30, 30 vs. 10 °C) difference and valance of reverse salt flux (RSF) in forward osmosis membrane. Algae metabolized materials had high removal efficiency (94–99%) at all experimental conditions. According to the temperature difference, the absorption percentage of geosmin and 2-MIB on the FO membrane was 76, 75% and 75, 55%, respectively. However, adsorption percentage of toxin (MC-LR) materials were observed to be 11 and 85%, respectively. Temperature-dependent parameters such as water and solute viscosity & diffusivity, membrane intrinsic properties, have effects on the removal mechanism and rate. Consequently, the results from this research provide meaningful information on not only the removal of algae metabolized materials like micropollutants but also the water treatment process with consideration of the temperature conditions (temperature difference).
