What is an anti-Legionella filter used for?
For safe protection of all domestic or hospital residents, WASE has tubular filters available that can be used in health care facilities to eliminate possible contamination of water (eg Legionella) for home use at points of use . These filters provide a very effective means of protection and prevention for patients and residents of pathogens in public or private buildings.
“FILT’RAY FILTER 2G: ELIMINATES ALL MICRORGANISMS IN ONE GESTURE”
The tubular microfiltration membrane is a high performance technology for removing all microorganisms present, such as Legionella bacteria, in water or in fluid. Microfiltration is a method of physically treating water (or other fluid) using a semi-permeable membrane with defined porosity, varying depending on the application, but conventionally comprised between 0.1 and 10 μm. Filtration is called the degree of sterilant when the pore diameter is less than 0.22 μm.
When the water undergoes pressure to pass through the filter membrane, the suspended particles are retained because they are larger than the pore size of the filter:
• suspended matter: colloids, mineral particles, organic waste …
• microorganisms: bacteria, mycobacteria, cyanobacteria, mycoplasmas, protozoa, algae, fungi, fungal or bacterial spores …
Filtration is called the sterilizing degree when the pore diameter is less than 0.22 μm.
2nd GENERATION FILTERING TECHNOLOGY
There are several membrane technologies in the field of water filtration. Second-generation tubular membranes are composed of several porous tubes arranged in parallel, providing a filtration surface that allows a significantly greater exchange and therefore a higher production rate.
ADVANTAGES OF TUBULAR MEMBRANE
VERSATILITY
Tubular membranes can be used in multiple applications, processes and sectors:
• Applications for purification, clarification, separation of proteins, sterilization;
• Reverse osmosis, nanofiltration (porosity: 0.001 microns – 0.01 microns) (porosity less than 0.001 micrometers), Ultrafiltration (porosity: 0.01 microns – 0.1 μm) and microfiltering (porosity: 0.1 μm – 10 μm);
• Chemical Sector, agri-food, potable water treatment, analysis, health, hospitals …
TRUST
Microfiltration at 0.1 μm ensures the complete elimination of bacteria and other aquatic microorganisms except viruses (most of them are less than 0.1 μm in size). The reliability of tubular membranes for bacterial sterilization is assured by ASTM F 838-05 (the assay evaluates the membrane’s ability to retain Brevundimonas diminuuta, the smallest known bacterial species measuring 0.3 microns). In hospitals, tubular membrane microfiltration is the most efficient treatment method to obtain bacteriologically controlled water at points of use.
COMFORT
Aqua-tools Tubular Plastic Membrane Infection Control Solutions provide clear benefits for user comfort and ease of maintenance:
• High output rate;
• Good tolerance against clogging;
• Good resistance to physicochemical variations of water (variations in hardness, high concentration of Chlorine or other disinfectants, acid or basic pH, high pressure and temperature of the network);
• High bacterial retention capacity for long-term use (31 and 62 days and 3 and 4 months);
• A bacteriostatic surface action to limit cross-contamination and re-contamination;
• Reduced cost for regular renewal (single-use product);
• Easy maintenance: faucet or shower filters can be replaced quickly thanks to a universal screw and / or clip-on system for perfect stability and sealing.
