Regenerate: BIOREMED ALGAE®

Coastal water bioremediation services

Improves water quality with macroalgae.

Captures nutrients and metals, with no added reagents.

More than 50 million litres of water treated, with an average reduction of 50% in nitrogen and phosphorus and maximums of 97%.

  • Fewer nutrients

    Captures nitrates, phosphates and ammonium.

  • A healthier environment

    Improves ecological potential.

  • No civil works

Low water renewal, nutrients that build up

Runoff, discharges and maritime traffic build up nutrients and metals in basins and marinas: murky water, microalgae and bad odours.

BIOREMED ALGAE® captures that load with macroalgae.

How it works

Five stages, one closed circuit

From the intake point to monitoring in Seangular.

BIOREMED ALGAE® module returning treated water to the sea in a port
  1. Intake

    Takes water from the critical point.

  2. Pre-treatment

    Filtering and disinfection.

  3. Bioremediation

    The macroalgae capture nutrients and metals.

  4. Return and harvest

    The water returns to the sea and the biomass is removed.

  5. Monitoring

    Data from every stage in Seangular.

Frequently asked questions

What people often ask us

If you can't find your answer, write to us.

Does it require civil works?

No. It arrives ready to connect and is installed on land, close to the intake point.

Do I need permits?

Depending on the location, the water intake and its return to the environment may require administrative authorisation. We look into this during the assessment and support you through the application process.

What happens to the biomass?

It is removed from the module periodically as part of the service.

When do results start to show?

The first results can be seen from two weeks after installation. To obtain representative results, we recommend a minimum of four months of operation.

Does it work all year round?

Yes. The module has bioremediation capacity at both high and low temperatures, regardless of the season.

What do you want to improve about your water?

We analyse your case and together we define the service you need.
