What is Ultrafiltration?

Ultrafiltration is a membrane technology that provides macro-modular separation to remove colloids, particles, large organics and microbiological contaminates.


Where can mobile ultrafiltration technology be applied?  

Mobile ultrafiltration - MWS

Veolia's mobile ultrafiltration unit (MOUF 4x85T®) is a trailer-mounted asset that produces up to 340 m³/hour (1,450 gpm) of treated water and is the largest mobile ultrafiltration technology available on the market today.  This asset is equipped with backwash and CIP systems inside and can be used for a wide range of applications including:

  • Pretreatment for process water applications (surface water, river, etc.)
  • RO Pretreatment - eliminate media filtration (MMF) or even settling processes
  • Post-treatment for wastewater applications (outlet of a WWTP / Polishing of TSS)
  • Wastewater reuse pilot testing applications
  • As final treatment to eliminate any particulates and bacteria from treated water
  • In place of settling equipment for precipitation, low-level clarification to remove the precipitated solids instead of using a clarifier
  • Recycle stream treatment
  • Cooling tower blowdown metals removal

What are the advantages of ultrafiltration?

What are the advantages of ultrafiltration?

Mobile Ultrafiltration Technology

Compared to other pretreatment technologies, ultrafiltration provides:

  • High and consistent product quality 
  • Tolerance to feedwater quality upsets
  • Small footprint 
  • 95% or better water recovery
  • Highly automated filtration and cleaning operations 
  • Module and skid integrity 
  • Usually extends RO membrane lifespan

Lower environmental impact: Conventional systems typically require chemical pretreatment such as coagulation and pH adjustment for the removal of silt and fine particles, but ultrafiltration can remove these contaminants just by size exclusion due to the small size of the membrane pores. This can lead to lower chemical consumption and lesser environmental concerns for wastewater disposal.

Ultrafiltration and Chemicals aid:  By comparison with the process of sedimentation associated with tertiary filtration,  ultrafiltration offers a much better barrier to stop the particles. Use of coagulant aid is sometimes not even necessary or, if needed, it can be minimized just to trigger a minimum reaction when a specific removal is targeted like organics or color removal. 

What are the advantages of using ultrafiltration ahead of reverse osmosis?

What are the advantages of using ultrafiltration ahead of reverse osmosis?

When ultrafiltration is applied as pre-treatment to an RO system, the RO can be designed with higher recovery, which reduces capital and operating costs.

How?  UF helps reduce fouling of the RO membranes. Utilizing UF as a pretreatment step before RO allows for reduced chemical cleaning frequency. Bacteria and virus removal also eliminates biofouling of the RO membranes. It also allows for the potential to operate the RO at a higher flux with fewer membranes and vessels. These advantages ultimately lower operating costs and minimize downtime of the units.
