Reduced energy costs and footprint
The VAL AQUA process offers an effective pre-treatment that significantly reduces energy needs and optimizes the use of space. By consolidating several functions into a single device, it makes it possible to reduce the footprint of installations, thus facilitating integration into existing infrastructures or new desalination projects.
Protecting membranes and improving water quality
By effectively eliminating viruses, bacteria and microalgae, VAL AQUA protects your desalination membranes, extending their lifespan and increasing their efficiency. This treatment ensures the production of high quality fresh water, which is essential to meet the most demanding standards.
Optimization of investments and installation flexibility
Thanks to VAL AQUA's ability to treat seawater near the coast, even in more polluted areas, it is no longer necessary to invest in long pipes to capture water away from the coast. This flexibility reduces initial investment costs and allows for faster and cheaper implementation of desalination projects.
Key figures
Maximum O₂ concentration in discarded water
Electrical consumption per m³ of treated water
Maximum oil/hydrocarbon concentration in wastewater
Particle extraction efficiency
Treated water flow per hour
No coagulants-flocculants or filters
Strong and rapid impact on the clogging index
The vacuum column makes it possible to treat seawater by exceeding ultrafiltration standards, i.e. water with a clogging index < 3 SDI.
The microbubbles created in the system trap impurities as they rise and create foam at the top of the column. This foam, which is sucked in by the vacuum, carries with it the particles that are trapped inside.
These extracted particles are between 0.3 and 100 um and are not trapped in conventional systems. This free passage technology thus never clogs or develops preferential passages.
