Ultrafiltration System (UF)
Pressure-driven UF skids removing colloids, bacteria and viruses — a robust barrier ahead of RO or as a standalone drinking water step.
- ZC-UF-50
- 5–200 m³/h
What makes this system different
- Filtrate SDI < 3
- Log-4 bacteria and virus removal
- Automatic CEB with sodium hypochlorite
- Expandable modular racks
Ultrafiltration removes particles down to 0.01 µm, giving a filtrate SDI below 3 and a log-4 removal of bacteria and viruses. It is the most economical way to protect a downstream RO plant.
Options
- PVDF or PES hollow-fibre membranes
- Automatic backwash and chemically enhanced backwash (CEB)
- Air-scour for high-solids surface water
- Integrity test on every production stop
