Advantages of tubular membrane microfiltration

Tubular membrane microfiltration

Tubular membrane microfiltration has several advantages compared to other filtration methods:


Tubular membranes are the most versatile.
They can be used for:

  • multiple applications: purification, clarification, protein separation, sterilization
  • various procedures: reverse osmosis (porosity less than 0.001 µm), nanofiltration (porosity: 0.001 - 0.010 µm), ultrafiltration (porosity: 0.01 0.10 µm), and microfiltration (porosity: 0.1 - 10 µm)
  • multiple sectors: chemical industry, food processing, drinking water treatment, analysis, healthcare, hospitality and catering, etc.


Microfiltration at 0.1 µm ensures that bacteria and other waterborne microorganisms are completely eliminated, with the exception of viruses (which are generally smaller than 0.1 µm).
Tubular membranes for bacterial sterilization are guaranteed by standard ASTM F 838-20 (the test assesses the membrane's ability to retain Brevundimonas diminuta, the smallest known bacterial species, which measures 0.3 µm). In hospital environments, tubular membrane microfiltration is the most effective treatment process for ensuring bacteriologically controlled water at the point-of-use. 


The hollow fiber membrane is very compact, meaning small devices contain a large filtration surface area.
AQUATOOLS filters are suitable for use with all mixers or faucets (even those with a low drop height).
The small size of the filters, particularly their height, considerably reduces the risk of bacterial retro-contamination on the spout of the mixer or faucet.

Superior performance - User comfort and easy maintenance

AQUATOOLS' tubular membranes provide clear advantages in terms of user comfort and simple maintenance:

  • a very large filtration surface: the highly compact fiber can filter a larger volume of water.
  • a higher flow rate at the outlet.
  • highly resistant to clogging: suspended matter remains on the surface of the tubular membrane, which reduces clogging and extends the filter's lifespan.
  • good resistance to physicochemical variations in the water: hard or soft water; a high concentration of chlorine or disinfectants; alkaline or acidic pH; high pressure and temperatures in the network.
  • a high bacterial retention capacity, which extends the lifespan. AQUATOOLS point-of-use filters have a lifespan of up to 3 months.
  • bacteriostatic surface action to limit cross-contamination and retro-contamination.
  • a lower cost suitable for regular renewal (single-use product).
  • easy to maintain: shower and faucet filters can be changed quickly thanks to a universal screw-in connector and/or a push-fit connector which ensures a sturdy, water-tight seal. Using the Filt’ray Scan mobile phone App, you can track maintenance across all points-of-use.
