Utilization of tofu whey concentrate by nanofiltration ...
In Fig. 1 it can be observed that the J values decreased during the nanofiltration (NF) process, with an average J value of 20.25 Lh −1 m −2.The same behavior was also observed by Kim et al. (2005) during the NF of tofu whey, and their J values ranged from 15 to 35 Lh −1 m −2.However, several factors can influence the NF performance (Baker, 2004), such as an increase in the osmotic ...
