ORISA ® purifies rainwater, surface water (streams, rivers, lakes, ponds) and groundwater (water tables, wells) from their microbiological contamination.
The highest performance in ultrafiltration. ORISA ® ^{filters bacteria, viruses, micro-organisms and parasites such as protozoa, but also microplastics and other suspended matter present in the water to be filtered. Its ultrafiltration (UF) membrane is made in France and composed of hollow fibers with extremely fine pores (0.01 microns).}

Features of the Orisa Fonto De Vivo water purifier

• Bacteria (LOG 8), viruses (LOG 5), microorganisms, parasites, protozoa, suspended matter (sediments, microplastics, etc. )

Filtration efficiency
at 99.999999% for bacteria as well as protozoa:

• E coli
• Campylobacter jejuni

Filtration efficiency 99.999% for viruses:

• Bacteriophage (MS-2)
• Bacteriophage (phiX-174)
• Murine norovirus

Filtered water flow up to 3 L/min, or 180 L/h , variable depending on the pumping speed and the turbidity of the water. Filtration capacity: up to 20,000L* Prefiltration: 50 μm Turbidity of incoming water: optimal performance of 1 to 50 NTU Turbidity of outgoing water: <0.1 NTU after filtration Above 50 NTU, pre-filtration with a cloth and decantation are recommended. Temperature of water to be filtered: 5-40°C The lifespan of an ultrafiltration membrane depends on the use, the number of users, the volume filtered, the turbidity of the water, the conditions of use and maintenance operations. Beyond its lifespan, the membrane can be replaced.

An autonomous and innovative water purifier:

ORISA ^® is equipped with technical and innovative features which give it great durability.
* The 50micron pre-filterretains larger particles. It is easily cleaned using the brush provided.
* Water circulation continues in the boundary membrane clogging and prolongs its lifespan.
* Integrated backwashing (patented solution) is a simple operation and rapid which reverses the direction of water circulation to unclog the pores of the UF membrane and thus preserve its permeability. A compact water purifier:

Dimensions: 42.5 x 17 x 12 cm

Weight: 2.1 kg
