Parameters
Feed water requirements (AquaUV data sheet)
| UV transmittance (UVT) | > 75 % |
| Suspended solids | < 10 mg/L |
| Iron | < 0.3 mg/L |
| Manganese | < 0.05 mg/L |
| Hardness | < 120 mg/L |
| Tannins | < 0.3 mg/L |
| pH | 6,5 – 9,5 |
| Color | None |
| Ambient temperature | 2 – 40 °C |
| Maximum pressure | 8.6 bar (125 psi) |
Nominal flows assume UVT > 75%. With lower-transmittance water, the flow per unit must be reduced.
