OVERVIEW
A PHYSICAL BARRIER AGAINST PARTICLES & BACTERIA
UF membranes have extremely fine pores that physically block suspended solids, bacteria and most viruses. The result is clear, low-turbidity water with stable quality, even when the raw water changes with the seasons.
​
UF can be used on its own for river and surface water, or as pretreatment before RO, where it protects the RO membranes better than media filters alone.
TYPICAL USES
- River and surface water treatment
​
- Pretreatment before seawater or brackish RO
​
- Water reuse after wastewater treatment
​
- Drinking water for communities
HOW IT WORKS
INSIDE THE UF SYSTEM
Raw water passes a strainer, then flows through UF membranes from the outside in. The membranes are backwashed automatically to keep them clean and the flow steady.
