, The polymer solution was mixed on a rollerbank for at least 48 h and degassed for 24 h before the spinning process. The polymer solutions were pumped through the spinneret using a speed of 1 mL/min at room temperature (the dimensions of the spinneret are listed in Table C1 below). To create the bore, ultrapure water was pumped through the spinneret with a speed of 5.8 mL/min, PES-SS2 hollow fiber membranes were prepared by dry-wet spinning via immersion precipitation. First, 15 wt% PES was dissolved in NMP and then 2 wt% SS was added
