Results from V max analysis for filtration of 30 nm latex particles in SWW through nanocellulose filter papers
| Filter paper thickness [µm] | Filtration overhead pressure [bar] | Slope of linear fit [1/V max] | V max a) [L m−2] |
|---|---|---|---|
| 9 | 1 | 1.3 (±0.6) × 10−3 | 9.7 (±4.6) × 102 |
| 9 | 3 | 2.5 (±0.1) × 10−3 | 4.0 (±0.2) × 102 |
| 29 | 1 | 1.4 × 10−4 b) | 7.4 × 103 b) |
| 29 | 3 | 5.7 (±0.3) × 10−4 | 1.8 (±0.1) × 103 |
a)
Values for V max were obtained at a particle concentration of 1011 mL−1
b)
The second filtration exhibited a negative slope in the V max analysis.
