Request Information

Vantage™ UFI ultrafiltration systems offer a robust system designed to remove suspended solids and organic impurities from a variety of different water streams.

Ultrafiltration (UF) is quickly becoming the process of choice over conventional technology for the following reasons:

  • Superior protection of downstream equipment (i.e. RO systems) to reduce fouling and extend equipment life.
  • UF membranes provide a physical and verifiable barrier to remove suspended solids.
  • Consistent quality regardless of feed water conditions.
  • SDI's typically less than <2.
  • Smaller footprint by replacing multiple conventional treatment steps into one filtration step.
  • Fewer chemicals with less waste, resulting in lower operating costs.

Vantage™ UFI System Configuration
Vantage™ LPU modules are manifolded together into racks and combined with pumps and controls to form a Vantage™ UFI system.

Vantage™ UFI systems are available in six models – 4, 8, 12, 24, 36, and 48 module racks. Additional configurations provide up to four racks (i.e. 4 x 24 module racks). Additionally, systems are available with:

  • Evoqua or Allen-Bradley control packages with HMI touch screen interface.
  • Manual/auto backwashing strainer options.
  • Completely automated backwash and chemical-enhanced backwash capabilities.
  • VFD-controlled feed pumps for ease of operation and energy savings.
  • Completely skidded packages with short lead times.

Membrane Detail
Multibore® ultrafiltration (UF) membrane technology combines seven single capillaries into one, durable membrane fiber. This construction significantly enhances the physical strength and reliability of the membrane, virtually eliminating fiber breakage. With a nominal pore size of 0.02 microns, the UF membrane efficiently removes turbidity, particulates, bacteria and pathogens, delivering consistently high-quality water, independent of changes in the raw water quality. The modified polyethersulfone (PES) membrane is durable over a wide pH range and highly resistant to fouling by organic matter.

Module Detail
At the heart of the Vantage™ UFI system is the Vantage™ LPU (low pressure ultrafiltration) module. Multibore® fibers are bound together to form a filter module encapsulated into an economical low-pressure PVC housing. The unique design of the module reduces external piping and pipe supports by integrating the feedwater manifolds into the end cap of each module. Through an annular gap between the shell and distribution pipe, filtrate is collected or backwash is introduced into the module. This results in a nearly constant radial velocity across the module diameter.

Vantage™ LPU modules are manifolded together into racks and combined with pumps and controls to form a Vantage™ UFI system. They are available in six models - 4, 8, 12, 24, 36, and 48 module racks. Additional configurations provide up to four racks (i.e. 4 x 24 module racks).
