Table 2. Average diameter, filtration time, and WRV of DES-LCNF and Enz-LCNFs
| Sample | Enzyme concentration Sample (%) | Enzymatic treatment time (h) | Average diameter time (h) (nm) | Filtration time (sec) | WRV (%) |
| DES-LCNF | - | - | 20.7 ± 4.0 | 111 | 1,558.0 |
| Enz-LCNF | 1 | 24 | 20.4 ± 3.3 | 111 | 1,496.4 |
| 3 | 12 | 18.6 ± 3.2 | 98 | 1,514.3 |
| | 24 | 17.0 ± 3.1 | 66 | 1,465.3 |
