ORISA® humanitarian durable water filtration equipment

FAMILY AND COMMUNITY WATER FILTRATION

ORISA^® water purifiers at the service of NGOs and local communities

Since 2021, ORISA^® purifiers have been deployed by international NGOs and local associations as part of development and humanitarian emergency programmes.

Following the deployment of more than 20,000 ORISA^® purifiers in 50 countries

The feedback collected between 2021 and 2024, highlights that ORISA^® is particularly suitable, if not the best solution, in the following situations:

Everyday home water filtration equipment.
For families in rural or peri-urban areas, as well as nomadic populations who have no access to water.
Community water filtration solution for collective establishments
In schools, health centres, humanitarian camps, emergency bases, etc.
Emergency equipment for Rapid Response Mechanism (RRM)
For epidemics or disasters (climatic, conflict-related) until the situation is restored.
Collective or family emergency stock
In response to precariousness and disasters requiring emergency intervention.

A complete range for great durability

We have developed ORISA^® water purifiers in response to specifications drawn up with the involvement of major French and international NGOs : Doctors Without Borders, the French Red Cross, Solidarités International, Médecins du Monde, Handicap International, Terre des Hommes Lausanne, Premières Urgences
What's more, we have developed a range of sustainable solutions to ensure the continuity of our commitments beyond humanitarian operations. We offer dedicated filtration equipment, as well as accessories and spare parts that are both sustainable and repairable.

WATER FILTRATION EQUIPMENT

How does ORISA^® work?

Fresh water treatment wherever you are
ORISA^® purifies rainwater, surface water (streams, rivers, lakes, ponds) and groundwater (water tables, wells) from microbiological contamination and suspended solids and micro-plastics.
High-performance
Weighing just 2kg and measuring 42.5cm, ORISA^® has a highly effective ultrafiltration membrane that eliminates micro-organisms that can cause health problems. LOG 8: 99.999999% of bacteria and protozoa eliminated; LOG 5 99.999% for viruses.
Filtration efficiency
Pre-filtration: 50 μm
Ultrafiltration : 0.01 μm (5000 times smaller than a human hair)
Turbidity before filtration: 1 to 50 NTU (optimum performance)
Turbidity after filtration: < 0.1 NTU
Manual pumping
To filter water, the ORISA^® water purifier requires nothing more than arm strength. A very moderate strength, since even a child can use it easily, as our deployments in schools and families have shown.
3L/min - 180/L per hour
The filtration rate depends on the turbidity of the water to be filtered, and can be as high as 3L/min, even for water with a high turbidity index, if it is pre-filtered. Integrated cleaning maintains filtration efficiency.
Sustainable system
An ultrafiltration membrane that filters 20,000 litres of water and can be replaced to ensure the longevity of this durable water filtration system. This makes it an excellent device for both collective emergencies and long-term family use.
Integrated cleaning
ORISA^® has an integrated cleaning system based on a manual backwashing operation. The direction of water flow is reversed to unclog the membrane pores and considerably extend its life.
Approved by the WHO
Approved by the WHO's international assessment programme for domestic water treatment technologies (HWTS round III), which awarded ORISA^® the "Complete protection: three stars" performance level.
Laboratory tested
The effectiveness of our water filtration equipment has been verified by the Institut Pasteur, whose tests reveal optimal filtration of biological contamination and suspended matter.

A simple but ingenious system

Pumped filtration
1. Constant water circulation for limited clogging.
2. No point of contact between dirty and filtered water to limit the risk of recontamination of clean water.
Pressure build-up for cleaning
Backwashing phase 1: Pressurising the clean water tank to backwash the ultrafiltration membrane.
Decompression and backwashing
Backwash phase 2: Reversal of the water flow direction to unclog the pores of the ultrafiltration membrane.

Adaptability

Designed for most water installations

Thanks to its filtration capacity and the versatility offered by its accessories, ORISA^® can be adapted to most water storage and supply installations and devices.

The water to be filtered can be collected and stored before treatment using an elevated, semi-buried or buried cistern, a well or a borehole, or using a water tank.

What's more, it can be adapted to most containers: buckets, jerrycans, kettles, etc.

Our accessories can be used to offset water pre-filtration or to connect ORISA^® to a (non-chlorinated) water tap, for automated filtration.

Ease of use at the cutting edge of innovation.

Manual pumping
Quick start-up, simplified and immediate filtration and instant maintenance.
Integrated cleaning
Backwashing in just a few seconds, on a daily basis, greatly increases longevity.
