The new UFLEX™ ultrafiltration systems are skid-mounted, reliable and compact solutions for removing suspended solids, most bacteria and log4 viruses.
Overview
Permeate Net Flow:

- 5.8 to 27.1 m3/h (min. 50 lmh / max. 110 lmh) per skid
- 27 to 108 m3 for two up to four skids in parallel
Typical Applications:
- Industrial process water
- Protection/pre-treatment for RO or Ion Exchange
- Turbidity & bacteria removal for Drinking water supply
- Swimming pool water
- Water recycling & reuse
Features & Benefits:
- Fully automatic operation with no operator involvement
- Automatic Hydraulic backflush & CEB backwash with connections
- Integrated and simple use controller for easy operation and maintenance
- Module vertical mounting for space saving
- Skid modular and flexible design enabling easy production capacity extension
- One controller to manage up to 4 skids in parallel mode for cost saving
Type of water to be treated
- City water
- Well water
- Surface water*
- Waste water*
* Coagulant dosing unit is necessary before filtration process and/or module recirculation pumps (excluded from our scope)de for cost saving
