Specializing in the manufacture and
development of hollow fiber membranes.

PES *DB Ultrafiltration
Hollow Fiber Membranes

Ultrafiltration is a low-pressure membrane process, capable of removing colloidal materials, fine suspensions, bacteria, virus, suspended solids and large molecular weight organic materials depending on the Molecular Weight cutoff of the membrane.

Matrix Membranes Inc. Ultrafiltration Hollow Fiber Element Modules are specially manufactured utilizing different fiber diameters and pore sizes. Made from polyethersulfone (PES) a hydrophilic, chemically stable polymer capable of operating in aggressive environments. Matrix Ultrafiltration Hollow Fibers have separation layers on both sides of the fiber (double skinned) and can be operated bi-directionally.

HF *DB Ultrafiltration Membrane Module Features

  • Tolerant of oxidants, chlorine, chlorine dioxide, hydrogen peroxide, ozone
  • Stable with a wide range of cleaning chemicals and in aggressive environments
  • Reduced energy costs, high productivity
  • Made up of resistant hydrophilic polymers that have low fouling effects
  • Stable at wide range of pH
  • Double-skin feature offers operating flexibility for both "Inside-out" and "Outside-in" configurations
  • Back-flushable; extending production run time between cleanings

Applications

  • POU-POE systems, Potable Water, >6 log reduction of Bacteria, >4 log Virus, Cysts and reduced turbidity

POU HF Ultrafiltration
RO Element Replacement

Ultrafiltration is a low-pressure membrane process, capable of removing colloidal materials, fine suspensions, bacteria, virus, suspended solids and large molecular weight organic materials depending on the Molecular Weight cutoff of the membrane.

POU Ultrafiltration Hollow Fiber Elements are made of polyethersulfone (PES) a hydrophilic, chemically stable polymer. POU Ultrafiltration elements have a separation membrane on both sides of the hollow fiber (double skinned*).

Membrane Module Features

  • Direct replacement for POU RO Elements
  • Fits most standard 12” RO membrane housings
  • Ease of use in existing systems and designs
  • Long life - up to three years
  • More efficient than RO can be 100% efficient
    (depending on application)
  • Retains minerals as recommended by WHO
    (World Health Organization)
  • 6 log reduction of Bacteria, Cysts, Viruses
  • Turbidity reduction

Applications

  • Home drinking water systems
