Filtered, bio-secure and translucent seawater
Ensure the purity of your shells with an innovative system that optimizes depuration while reducing costs and environmental impact
Secure your livestock water with reinforced bio-security
The VAL AQUA system effectively eliminates viruses, bacteria and fine particles from your farming water, thus guaranteeing optimal conditions for the depuration of shellfish, while maintaining continuous and uninterrupted operation.
Lower your operating costs with a versatile solution
VAL AQUA combines the functions of clarification, oxygenation and filtration into a single robust and reliable device, thus eliminating the need for multiple filters and minimizing the risks of clogging, while offering simplified management and a significant reduction in your energy costs.
Optimize water quality with eco-responsible technology
Thanks to effective oxygenation (maintaining 90% saturation) and reducing CO₂ by 50% in a single pass, VAL AQUA ensures clarified and enriched seawater, while consuming little energy and requiring minimal maintenance, for a more sustainable and efficient operation.
A breakthrough solution to solve the limitations of current shellfish purification systems
- Presence of bacteria and viruses in water
- Abundance of small particles < 30 µm that are not captured by conventional filters and reduce the effectiveness of UV treatments
- Decrease in dissolved oxygen concentration in water
- Accumulation of dissolved CO2 in water
- Energy cost of the solutions put in place to solve these problems
99.9% reduction in bacterial and viral loads
Elimination of pathogens
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 30 um and are not trapped in conventional systems.
Some performance figures for VAL AQUA
Minimum size of extracted particles
Transmittance indicating clarification of the water
Reduction in bacterial load
Maximum quantity of shells treated by a VAI1400 on 200 m³ of water
Maximum power consumption per m³ of treated water
Lower viral load
Optimal UV efficiency
Particle extraction by the VAL AQUA system also makes it possible to trap bacteria and viruses, thus ensuring the biosecurity of livestock water.
Clarifying water ensures optimal UV efficiency, coupled with the extraction function that eliminates degraded particles that UV and ozone treatments neutralize but leave in the environment.
It is possible to extract continuously or only a few hours a day.
Regulation of the concentration of O₂ and CO₂
The bubbles associated with the vacuum created at the top of the column make it possible to achieve unparalleled aeration and degassing efficiency.
90% Minimum oxygen saturation level
50% Reduction in the quantity of CO₂ in a single pass
“We have 230 m3 of shellfish purification tanks for a volume to be treated of 430 m3 of the Thau pond. Initial plans included conventional pump technologies, sand filters, and UV treatments.
Swapping for the COLDEP device alone allowed us to consume eight times less electricity, and improve performance. superior water quality both in terms of filtration and purification as well as in oxygenation. ”
