Boost the growth of your microalgae

With a water treatment solution that optimizes oxygenation, eliminates impurities, and reduces your operational costs

Improve water quality for optimal microalgae growth

The VAL AQUA system purifies water by effectively removing fine particles and contaminants, while optimizing oxygenation. This process ensures an ideal environment for the rapid and healthy growth of microalgae.

Increase the effectiveness of your nutrient intake

Thanks to VAL AQUA's ability to inject nutrients directly into the column, they are dispersed evenly and effectively in the water, ensuring that your microalgae benefit from ideal conditions for maximum development.

Reduce costs while increasing productivity

VAL AQUA combines purification, oxygenation and distribution of nutrients in a single device, thus simplifying your operational management. With low energy consumption and low maintenance, you benefit from a significant reduction in costs while maximizing microalgae production.

Harvest — Concentration — Biosecurity

This is a very good way to preconcentrate a microalgae culture before a possible additional centrifugation step, for example.

The particulate extraction of VAL AQUA also makes it possible to trap bacteria and viruses, thus ensuring the biosecurity of the installation.

Clarifying water also improves access to light, and therefore promotes photosynthesis.
