Our technologies

The water business of ACCIONA Research and technology innovation department are behind an efficient management and a sustainable development.

As result of the development investment, it has been registered more than 25 patents related to new desalination, purification and reuse water technologies.

ACTIDAFF®

A water pre-treatment system that combines flotation and granular bed filtration in a single tank.

ACTIDAFF® has many applications: water treatment with algae, water with high concentrations of grease and oil and solids in suspension.

ULTRADAF®

Dissolved air flotation (DAF) is one of the processes applied for the treatment of water with a low content of solids in suspension, floc concentrations between 5 and 50 mg/l, e.g.: Production of potable water, Pre-treatment in the desalination of seawater, Treatments for the re-use of treated water.

It is also applied to water with a high solid content, provided its hygroscopic characteristics allow its floatability (algae, biological sludge, etc.).

BIOFILPAS®

Biolfiltration is a combination technology in which solid matter is retained mechanically through filtration and the contaminants contained in the water being treated biologically are transformed through the use of microorganisms.
