Eliminate all micro-organisms
In a single move
Using tubular membrane
Microfiltration is a process for physically treating water (or other fluids) using a semi-permeable membrane with a defined porosity that varies depending on the application, but generally falls between 0.1 and 10 µm. When water is passed through the membrane while under pressure, any suspended particles larger than the size of these pores are trapped. The filtered water is therefore free from:
• suspended material: colloids, mineral particles, organic residue, etc.
• micro-organisms: bacteria, mycobacteria, cyanobacteria, mycoplasma, protozoa, algae, fungi, bacterial or fungal spores, etc.
Filtration is called sterilizing-grade filtration when the diameter of the pores is less than 0.22 µm.
There are many membrane technologies in the water filtration field. Second generation tubular membranes, which are composed of multiple parallel porous tubes, provide a greater surface exchange area and therefore an increased flow rate. The tubes differ in composition (plastic, composite, mineral or organic), porosity and diameter.

Tubular membranes provide the greatest versatility. They can be used for:
• multiple applications: purification, clarification, protein separation, sterilization, etc.;
• many procedures: reverse osmosis (porosity less than 0.001 µm), nanofiltration (porosity: 0.001 µm - 0.01 µm), ultrafiltration (porosity: 0.01 µm - 0.1 µm) and microfiltration (porosity: 0.1 µm - 10 µm);
• many sectors: chemistry, the agro-food industry, drinking water treatment, analyses, health, the hotel industry, etc.
Microfiltration using a 0.1 µm filter eliminates all bacteria and other waterborne micro-organisms, except for viruses (which are generally smaller than 0.1 µm). The efficacy of tubular membranes for bacterial sterilization is guaranteed by standard ASTM F 838-05 (the test evaluates the ability of the membrane to trap Brevundimonas diminuta, the smallest known bacterial species at 0.3 µm). In a hospital environment, tubular membrane microfiltration is the most powerful treatment method for producing bacteria-free water at the point of use. Learn more
The plastic tubular membranes produced by aqua-tools Infection Control Solutions provide several advantages for user comfort and ease of maintenance:
• high flow rate;
• high tolerance to blockage;
• high resistance to physico-chemical variations in water (hard or soft water, high concentration of chlorine or disinfectants, acidic or basic pH, high network pressure and temperature);
• high bacterial retention capacity for extended use (31 & 62 days and 3 & 4 months);
• surface bacteriostatic activity to limit cross-contamination and retrograde contamination;
• low cost to encourage regular replacement (single use product);
• simple maintenance: shower or tap filters can be changed quickly due to a universal screw cap and/or clip system that ensure complete stability and water tightness. Using the Filt’ray Data Manager™ tracking software, you can track maintenance activities at all points of use. Learn more

aqua-tools Infection Control Solutions filters are class 1 medical devices.
Before using the filters, familiarize yourself with the technical and scientific features of each model (shower head or tap, sterile and non-sterile, 31 & 62 days and 3 & 4 months). Read the instructions before installing and uninstalling the filters. Used filters that are removed should never be sterilized or recycled, but must be incinerated.
