Özet

The effect of milk rheology on membrane fouling remains a challenging problem for long-term microfiltration. This study aimed to investigate the effects of viscosity changes as a function of weight reduction factor (WRF) and temperature on the performance of commercial polyethersulfone membrane. The retentates were obtained from skim milk in batch concentration mode with WRF of 2.5, 3.5, 4.5 and 5.5, to investigate the effect of change in feed composition on polyethersulfone (PES) membrane performance. The performance of the PES membrane was evaluated with pure water before the microfiltration of milk and it was discovered that using low transmembrane pressure and pH levels above 5.0 resulted in more consistent water flux. The two -fold increase in the transmembrane pressure caused up to ten -fold increase in irreversible fouling resistance. At WRF greater than 2.5, the non -Newtonian pseudoplastic behaviour of the samples obtained became more pronounced, resulting in a more pronounced decrease in flux for the batch concentration mode at 55 degrees C compared to the total recycling mode. The rheological and chemical composition properties of the streams affected by varying microfiltration parameters are important for the dairy products in which they are used, as well as for innovative production processes where quality of whey proteins is required to be preserved.
